Proxbox
Proxbox is a NetBox plugin that synchronizes Proxmox infrastructure data into NetBox. It keeps your DCIM up-to-date with real Proxmox clusters, nodes, virtual machines, containers, backups, and Firecracker micro-VM inventory used by the NMS Cloud runtime.
What It Does
Proxbox discovers and syncs the following from Proxmox into NetBox:
- Clusters and Nodes — Proxmox cluster name, mode (cluster/standalone), quorum status, node count, and Proxmox VE version. Each node includes online status, IP address, CPU usage, memory usage, and uptime at sync time. Optionally link to NetBox Cluster and Device objects.
- Virtual Machines — VM status, resources, and configuration
- Standalone browser console — a permission-gated Console tab on synchronized NetBox virtual machines, with QEMU noVNC/terminal and LXC terminal access relayed through proxbox-api without another management UI or browser-visible Proxmox credentials
- Containers (LXC) — Container details and settings
- Firecracker Cloud inventory — Host pools, host-agent VMs, image templates, and provisioned micro-VMs exposed separately from QEMU/LXC for NMS Cloud provisioning
- VM Snapshots — Point-in-time snapshots for recovery
- VM Backups — Backup jobs and restore points
- Storage — Datastores and storage content
- Network Interfaces and IPs — Proxmox NICs (
net0,net1) as core NetBox VM interfaces, optional guest-OS interfaces (ens18,eth0) as pluginGuestVMInterfacerows, and IP addresses assigned to VMs and containers - Backup Routines — Backup job definitions from Proxmox
- Replications — Replication job status and configuration
- Data Protection Calendar — Month and ISO-week views for backups,
- Opt-in service monitoring — Proxmox endpoint systemd service state collected through the optional
netbox-rpcprocedureos.linux.proxmox.show_systemctl_services
Note: All metrics (CPU, memory, uptime, etc.) are captured as point-in-time snapshots at sync time, not continuous monitoring.
Sync runs on-demand from the NetBox UI or scheduled automatically via NetBox's job system.
Backend API keys are adopted fail-closed without making the token field
mandatory. The exact URL/IP, port, and TLS policy saved in the NetBox UI is the
automatic-discovery allowlist: the plugin probes only that configured target,
never follows redirects, reuses an encrypted key only after the target accepts
it, and generates a key only for an empty backend's one-time bootstrap. With no
endpoint row, discovery is bounded to PLUGINS_CONFIG and same-site names
derived from NetBox's trusted public origin; it never scans the network. An
initialized backend whose key is not locally recoverable remains fail-closed
and pending. Disabled endpoint rows make no network calls. Operators can still
submit a key explicitly for manual rotation or recovery.
Additional Optional Plugins
Proxbox can be extended with standalone companion plugins. Install only the
plugins you need; netbox-proxbox remains the base plugin and must be enabled
before any companion plugin. The infrastructure inventory plugins declare
netbox-proxbox>=0.0.18 as a dependency, while netbox-packer and
netbox-rpc follow the same operational conventions for the Proxbox plugin
family. netbox-rpc is an operational companion: when it is installed,
netbox-proxbox can run audited SSH procedures against Proxmox hosts (for
example installing the proxbox-api cloud-image-build SSH key on a node, or
collecting systemd service status for an endpoint) through the netbox-rpc engine
instead of handling SSH itself. The integration is a soft dependency — see
netbox_proxbox/integrations/rpc.py.
A companion package being present in the virtual environment does not enable
its Django app. Proxbox registers branching signals and PDM URL overrides only
when netbox_branching or netbox_pdm, respectively, is listed in PLUGINS;
installed-but-disabled companions therefore remain inert. Once a companion is
enabled, its imports are mandatory and startup fails if the installation is
broken. Encryption recovery is the one fail-closed maintenance exception:
netbox-pbs older than 0.0.1.post1 may start so its migrations can run, but
recovery and key mutation remain blocked until its encrypted-field schema is
upgraded.
| Package | NetBox plugin | What it adds |
|---------|---------------|--------------|
| netbox-pdm | netbox_pdm | Inventories Proxmox Datacenter Manager endpoints and the PVE/PBS remotes managed by PDM. It links PDM remotes back to Proxbox Proxmox endpoints and, when installed, netbox-pbs backup servers. |
| netbox-pbs | netbox_pbs | Inventories Proxmox Backup Server infrastructure, including PBS servers, datastores, backup snapshots, and scheduled job history. |
| netbox-ceph | netbox_ceph | Adds read-only Ceph cluster inventory for Proxmox-managed Ceph: clusters, daemons, OSDs, pools, filesystems, CRUSH rules, flags, and health checks. |
| netbox-packer | netbox_packer | Tracks HashiCorp Packer image definitions and build execution records for Proxmox VM templates and image-factory workflows. |
| netbox-rpc | netbox_rpc | Audited SSH/RPC procedure engine. netbox-proxbox optionally uses it to install SSH keys on Proxmox hosts and to collect Proxmox endpoint systemd service status via netbox_proxbox.integrations.rpc. |
Cloud-Init template-image creation through netbox-packer is a separately
authorized endpoint capability. The selected ProxmoxEndpoint must be enabled
with both allow_writes=True and the default-off
allow_packer_template_builds=True; the latter grants only netbox-packer
template builds. The Templates-tab action remains disabled until both gates
pass, and the narrow value is pushed to proxbox-api for enforcement at its
final write boundary only when the endpoint is also enabled and the broad gate
is open. Disabling the endpoint or either gate revokes that backend capability;
the endpoint detail page displays the explicit narrow assertion for audit. The
save-time push runs only after the NetBox transaction commits and records the
last backend-confirmed grant. Endpoint deletion remains blocked after an
unsuccessful revocation until proxbox-api confirms the grant is false. The two
template-build REST actions also require core.run_proxmox_action, recheck all
three endpoint gates before backend access, and translate the NetBox primary key
to proxbox-api's independent endpoint ID.
For a standard NetBox virtualenv install, activate the NetBox environment and install the packages you want:
source /opt/netbox/venv/bin/activate
pip install 'netbox-pbs>=0.0.1.post1' netbox-pdm netbox-ceph netbox-packer
Enable the selected plugins in netbox/netbox/configuration.py. Keep
netbox_proxbox first. If you enable netbox_pdm, enable netbox_pbs before
it because PDM can link to PBS server records.
PLUGINS = [
"netbox_proxbox",
"netbox_pbs",
"netbox_pdm",
"netbox_ceph",
"netbox_packer",
]
Run migrations for the selected plugins, preserving the same order:
cd /opt/netbox/netbox
python3 manage.py migrate netbox_proxbox
python3 manage.py migrate netbox_pbs
python3 manage.py migrate netbox_pdm
python3 manage.py migrate netbox_ceph
python3 manage.py migrate netbox_packer
python3 manage.py collectstatic --no-input
sudo systemctl restart netbox netbox-rq
For netbox-docker, add the selected packages to plugin_requirements.txt,
enable the matching plugin module names in configuration/plugins.py, rebuild,
and run migrations:
netbox-pbs
netbox-pdm
netbox-ceph
netbox-packer
docker compose build
docker compose up -d
docker compose exec netbox /opt/netbox/netbox/manage.py migrate
Full companion-plugin details live under docs/companion-plugins/.
The audited Proxmox write integration plan details the target Proxbox → RPC → OpenBao workflow, trust boundaries, secret and operation matrices, procedure output chaining, migration and installation runbook. It distinguishes existing integration from planned runtime enforcement; publishing the plan does not enable mandatory RPC writes.
Endpoint Enablement
Endpoint records are inventory/configuration objects even when disabled. For
ProxmoxEndpoint, NetBoxEndpoint, FastAPIEndpoint, PBSEndpoint,
PDMEndpoint, and companion endpoint objects that expose an enabled field,
enabled=False is a hard operational gate: netbox-proxbox keeps the row visible
in UI/API output, but status checks, backend registration, OpenAPI fetches,
sync scopes, keepalive probes, and startup/signal pushes must return before any
proxbox-api or remote-service connection attempt.
The Proxmox Endpoints list shows the Enabled column by default. Operators can
select multiple rows and use Enable Selected or Disable Selected to
toggle the local ProxmoxEndpoint.enabled flag in bulk; those list actions do
not call proxbox-api or Proxmox.
Disabled Proxmox endpoints render as a gray Disabled status badge on the list, detail page, and dashboard card. These UI surfaces do not attach live status polling metadata for disabled rows, so the browser does not repaint an administratively disabled endpoint as a red error.
Proxmox Endpoint Service Monitoring
Service monitoring is opt-in per ProxmoxEndpoint. An endpoint is eligible only
when allow_writes=True, access_methods="api_ssh", and the endpoint has a
complete registered SSH credential. Collection is agentless from the Proxbox
plugin perspective: netbox-proxbox creates a netbox-rpc RPCExecution for the
read-only procedure os.linux.proxmox.show_systemctl_services with params
{proxmox_endpoint_id, units} and assigned object set to the endpoint. The RPC
backend uses the endpoint's own SSH credential; netbox-proxbox does not open SSH
sockets or run shell commands itself.
Execution is asynchronous. Phase 1 queues the RPC job and records a pending
ProxmoxServiceCollection. Phase 2 runs from the periodic service-monitoring
tick and from the endpoint Services tab render path: completed executions are
projected into raw ProxmoxServiceSample rows, latest ProxmoxServiceStatus
rows, and endpoint heartbeat fields. A reachable=false RPC result is recorded
as an unreachable node outcome, not as a projection error.
Cloud Portal Endpoint Allowlists
ProxmoxEndpoint.allowed_tenants controls which Proxmox endpoint rows are
eligible for tenant-scoped NMS Cloud callers. An empty allow-list means the
endpoint stays in the default/global pool. A non-empty allow-list pins that
endpoint to the listed tenants.
The paired nms-backend contract is intentionally asymmetric: if a tenant has
no explicit endpoint grants, it may still see global/default endpoints; once
that tenant matches any explicitly granted endpoint, the backend hides the
global pool and returns only the explicit matches. Use this to pin a tenant
such as Confitec to a single cluster without changing the default pool for
other tenants.
Maintenance hardening notes
- Primary endpoint secrets are encrypted at rest.
ProxmoxEndpoint.password,
ProxmoxEndpoint.token_value, FastAPIEndpoint.token,
PBSEndpoint.token_secret, and PDMEndpoint.token_secret now write through
Fernet-encrypted *_enc database columns. The upgrade migration encrypts
existing values and creates ProxboxPluginSettings.encryption_key if it was
blank, so new endpoint saves do not persist those primary secrets in
plaintext columns.
- Encryption-key recovery is atomic and companion-aware. The Settings page
- Dual VM interface sync. The plugin model surface supports the new
guest_os_model strategy: keep Proxmox-side NICs as core
virtualization.VMInterface rows named net0/net1, and store guest-agent
OS names such as ens18 in GuestVMInterface. GuestVMInterfaceAddress
links those guest interfaces to the same core ipam.IPAddress rows already
assigned to the core VM interface. The older use_guest_agent_interface_name
flag is deprecated and only applies when vm_interface_sync_strategy is set
to legacy_rename.
- Operator repair path. If Proxbox custom fields or bootstrap setup vanish
/plugins/proxbox/sync-state/, reached from the **Repair / Rebuild
sync-state** link in the Proxbox Home page footer (it is intentionally kept
out of the navigation menu). It reconciles proxbox-api custom-field definitions,
queues a normal full sync job, and shows GET /extras/bootstrap-status output
for troubleshooting. See
Recovering / Regenerating Proxbox Data.
What's New in v0.0.27rc4
Current backend-runtime pairing: netbox-proxbox 0.0.27rc4 <-> proxbox-api 0.0.22.post1 <-> proxmox-sdk 0.0.13 <-> netbox-sdk 0.0.13. This netbox-sdk version is proxbox-api's REST dependency only and does not provide the semantic MCP bridge.
Paired with backend: proxbox-api 0.0.22.
- Virtual machines list search and filtering. The Proxbox virtual machines page now uses NetBox's
VirtualMachineFilterSet, exposes Results and Filters tabs, and keeps sync actions and pagination aligned with the API list view. - Actionable console recovery. Console failures now distinguish a healthy backend API from missing or invalid synchronized NetBox endpoint and node relations, provide stable diagnostic codes and exact remedies, and offer the existing full synchronization repair only to authorized operators with an explicit estate-wide scope warning.
- Feature retention. Retains the browser-console handoff, Proxmox metrics, and human-only soft-deleted VM purge surface from earlier
0.0.26.postreleases.
What's New in v0.0.26.post2
Current backend-runtime pairing: netbox-proxbox 0.0.26.post2 <-> proxbox-api 0.0.21.post6 <-> proxmox-sdk 0.0.13 <-> netbox-sdk 0.0.10. This netbox-sdk version is proxbox-api's REST dependency only and does not provide the semantic MCP bridge.
Paired with backend: proxbox-api 0.0.21.post6.
- Production browser console handoff. NetBox virtual-machine detail pages
buttons()
hook and open the corresponding NMS QEMU or LXC guest detail in a new tab;
the operator then selects the Console tab. See the complete configuration,
visibility, URL-construction, security, and test guide in
docs/features/browser-console.md.
- Proxmox metrics. Adds the independently configured InfluxDB metrics UI,
- Audited cleanup. Adds the human-only page for reviewing and purging

What's New in v0.0.23.post1
Backend-runtime pairing: netbox-proxbox 0.0.23.post1 <-> proxbox-api (guest-VM-interface writer build / next release) <-> proxmox-sdk 0.0.12 <-> netbox-sdk 0.0.10.
Paired with backend: guest-VM-interface writer build / next release.
- Universal guest OS interface model default.
vm_interface_sync_strategy=guest_os_modelis now the default for existing installs as well as new installs; migration0060supersedes the0.0.23upgrade backfill that kept configured installs onlegacy_rename. - Upgrade behavior change. Proxmox NICs stay as
net0/net1coreVMInterfacerows, guest-agent names such asens18are stored inGuestVMInterface, and operators who want the old renaming behavior can re-selectlegacy_renamein plugin settings.
What's New in v0.0.23
Backend-runtime pairing: netbox-proxbox 0.0.23 <-> proxbox-api (guest-VM-interface writer build / next release) <-> proxmox-sdk 0.0.12 <-> netbox-sdk 0.0.10.
Paired with backend: guest-VM-interface writer build / next release.
- Dual VM interface sync. Proxmox NICs stay as core
VMInterfacerows namednet0/net1, while guest-agent OS interfaces such asens18are stored inGuestVMInterfacerows. - Shared IP ownership.
GuestVMInterfaceAddresslinks guest interfaces to the same coreipam.IPAddressobjects already assigned to the mapped core VM interface. - Strategy control.
vm_interface_sync_strategy=guest_os_modelis the new default for fresh installs; existing configured installs are backfilled tolegacy_renameduring migration0059so upgrades do not silently rename interfaces differently. This 0.0.23 upgrade backfill is superseded by v0.0.23.post1.
What's New in v0.0.22
Backend-runtime pairing: netbox-proxbox 0.0.22 <-> proxbox-api 0.0.19.post5 <-> proxmox-sdk 0.0.12 <-> netbox-sdk 0.0.10.
Paired with backend proxbox-api 0.0.19.post5.
- Per-endpoint access methods. Proxmox endpoints now expose API-only vs API+SSH transport selection, with the selected
access_methodsvalue sent to the backend registration payload so backend SSH paths can enforce the same gate. - Endpoint operator controls. The form includes the Proxmox-side write-permission toggle, SSH credential-source selection, and a Fetch host key flow for pinned SSH fingerprints.
- Inventory and API coverage. This release includes tenant allowlists, bulk endpoint enablement, PDM endpoint sync, SDN inventory, Firecracker serializer hardening, and REST coverage for PBS/PDM endpoints plus read-only DeletionRequest and ProxmoxApplyJob audit endpoints.
- Certification refresh. NetBox compatibility remains
4.5.8through4.6.99, now validated through NetBoxv4.6.4.
What's New in v0.0.21
Paired with backend proxbox-api 0.0.18.post5.
- Sync-mode filtering at source. Per-record VM and VM-template filtering is enforced by the paired backend through
sync_mode_vmandsync_mode_vm_templatequery params, so disabled modes no longer create dependent NetBox objects for skipped VMs. - Batch and stream hardening. VM sync uses two-phase batch processing, isolates per-VM dispatch failures, matches interface-dense guest aliases by name, and emits partial-failure stream frames for operator visibility.
- Backend SDK pairing. This release pairs with
proxmox-sdk 0.0.12andnetbox-sdk 0.0.10only through the separate proxbox-api REST runtime.
What's New in v0.0.20.post3
Paired with backend proxbox-api 0.0.17.post1.
- Disabled endpoints never connect. Endpoint-like rows with
enabled=Falseremain visible as inventory/configuration records, but Proxbox status, keepalive, backend registration, OpenAPI, sync, startup, signal, PBS, PDM, and companion endpoint paths now return before any proxbox-api or remote-service connection attempt. - Maintenance guardrails. LLM and developer docs now describe the all-endpoint enabled-field invariant, and the regression suite covers PBSEndpoint/PDMEndpoint shared
EndpointBase.enabledbehavior plus shared guard wiring.
What's New in v0.0.20.post2
Paired with backend proxbox-api 0.0.17.post1.
- Latest Sync Jobs on the homepage. The plugin homepage now includes a read-only table with the five latest Proxbox sync jobs and a View all sync jobs button after the additional plugin endpoint cards.
What's New in v0.0.20.post1
Paired with backend proxbox-api 0.0.17.post1.
- VM-template sync job wiring.
ProxboxSyncJobnow calls the existingsync_vm_templates()stage, soProxmoxVMTemplateinventory is populated during full/scheduled syncs instead of staying empty.
What's New in v0.0.20
Paired with backend proxbox-api 0.0.17.
- IP-address ownership safety. The paired backend prevents VM-interface IP sync from taking over an address that already belongs to another interface.
- Interface-batch settings persistence.
interface_batch_sizeandinterface_batch_delay_msentered on the plugin Settings page now persist to the database.
What's New in v0.0.19
Paired with backend proxbox-api 0.0.16.
- Historical FastAPI endpoint token drift fix (superseded). v0.0.19 added an explicit-token recovery path for proxbox-api key rotation. Current code replaces its former bootstrap bypass with the fail-closed adoption boundary described above.
- Canonical FastAPI trust boundary. Direct-model and REST paths validate the backend authority before any request, reject URL injection syntax, bracket IPv6 literals, preserve omitted secret ciphertext, and treat disabled WebSocket/storage consumers as absolute no-network paths.
- PBS/PDM
hostcompatibility property.PBSEndpointandPDMEndpointnow expose ahostproperty bridging the field-name difference with proxbox-api's SQLite column. - PBS/PDM
timeout_secondscompatibility property. Both models now expose atimeout_secondsproperty to match the proxbox-api SQLite column name.
What's New in v0.0.18
Paired with backend proxbox-api 0.0.14.
- Full PVE 9.2 support. New models for SDN fabrics, route maps, prefix lists, and custom datacenter CPU models, plus automated sync services. Completed per-node firewall sync. HA arm/disarm action views.

NetBox support tiers
netbox-proxbox declares two NetBox support tiers, defined once in
netbox_proxbox/compat.py and shared verbatim
across the whole Proxbox plugin stack:
| Tier | NetBox range | What it means |
|---|---|---|
| Stable | 4.5.8 – 4.7.0 | Admitted silently. CI exercises v4.5.8, v4.5.10, v4.6.0, v4.6.6, and v4.7.0 GA. |
| Experimental | NetBox 4.7.x pre-release builds within the declared loader range | Loads for evaluation and warns once at startup; this is not a GA support promise. |
The GA support needs no configuration at all — no setting, opt-in flag, or install step. NetBox 4.7.x pre-release builds within the declared loader range are evaluation-only and emit an advisory warning. The existing 4.5/4.6 installs use the same package and can be upgraded to NetBox 4.7 without changing plugin configuration or database state.
WARNINGS:
?: (netbox_proxbox.W001) Proxbox is running on NetBox 4.7.0-beta2, which is
supported on an experimental basis only. Certified support covers NetBox
4.5.8 through 4.7.0. NetBox 4.7.0-beta2 is also an upstream pre-release:
upstream does not support pre-releases in production and does not guarantee
an upgrade path from a pre-release to the final release. Use it for
evaluation on disposable data only.
HINT: The plugin itself is operational on this release; this is a maturity
notice, not a plugin fault. Do not treat it as clearance to run a NetBox
pre-release in production — that restriction is upstream's, and silencing
this notice does not lift it. On an evaluation install you can quiet it with
PLUGINS_CONFIG['netbox_proxbox']['silence_netbox_compatibility_warning'] = True.
It is a warning, never an error — it cannot block NetBox from starting.
Silencing is for evaluation installs only. The notice above is the only thing telling you the release is unsupported upstream and has no guaranteed upgrade path to GA; quieting it does not change either fact. It does not admit a later prerelease or GA build.
To silence it, set the key in this plugin's PLUGINS_CONFIG entry:
PLUGINS_CONFIG = {
"netbox_proxbox": {"silence_netbox_compatibility_warning": True},
}
That silences both the system check and the startup log line.
Django's own SILENCED_SYSTEM_CHECKS is honoured too, but **not from
configuration.py** — NetBox'ssettings.pyimports an explicit list of
named settings and that one is not on it, so setting it there has no effect.
It only applies through NetBox's local_settings.py hatch, which upstream
labels unsupported. Use the PLUGINS_CONFIG key above.
NetBox releases below 4.5.8 and above 4.7.0 are refused by NetBox's stock
plugin version gate. Pre-release builds receive an advisory warning; exact GA
source and dependency provenance are verified by the CI matrix.
Upgrading to NetBox 4.7 means upgrading the whole plugin stack. A
Proxbox-family plugin left at the old 4.6.99 ceiling does not stop NetBox
from starting — settings.py catches the incompatibility, warns, and
silently skips that plugin. The symptom is an absence (missing views, API
routes and jobs), not an error, and a health probe against NetBox still
passes. Upgradenetbox-proxbox,netbox-ceph,netbox-packer,
netbox-pbsandnetbox-pdmtogether, then confirm each is registered with
apps.is_installed(...). On 4.5.8–4.6.x, mixed versions remain fine.
On upgrades. Keep all installed Proxbox-family plugins on GA-capable
releases before upgrading NetBox. The 4.5.8 floor remains supported, while
the declared ceiling is now 4.7.0.
Requirements
- NetBox 4.5.8 through 4.7.0, including official v4.7.0 GA
- Verified with NetBox v4.5.8 through v4.5.10, v4.6.0 through v4.6.6, and
5f06007e4c9bacc93ce17c1e645fc1143d60df3d; the source
matrix verifies release metadata and installs commit-bound, hash-checked
Python 3.12/Linux dependency locks
- Python 3.12+
- Proxmox VE 7.x, 8.x, or 9.x (PVE 9 requires
VM.GuestAgent.Auditon the API role; see "Troubleshooting" below for the PVE 9 auth checklist) - Proxbox API backend as a separately deployed service (see below)
Quick Start
Choose the installation path that matches your NetBox deployment:
- Standard NetBox install (venv on host): follow steps below.
- NetBox Docker install (
netbox-docker): use the Docker-specific workflow in Installing the Plugin in Docker-Based NetBox Deployments.
- Install the plugin into your NetBox virtual environment (host/venv deployment):
cd /opt/netbox/netbox
git clone https://github.com/emersonfelipesp/netbox-proxbox.git
source /opt/netbox/venv/bin/activate
pip install -e ./netbox-proxbox
- Enable the plugin in
netbox/netbox/configuration.py:
PLUGINS = ["netbox_proxbox"]
- Run migrations and collect static files:
python3 manage.py migrate netbox_proxbox
python3 manage.py collectstatic --no-input
sudo systemctl restart netbox
- Install the Proxbox API backend:
mkdir -p /opt/proxbox-api
cd /opt/proxbox-api
python3 -m venv venv
source venv/bin/activate
pip install proxbox-api
uvicorn proxbox_api.main:app --host 0.0.0.0 --port 8800
Or use Docker (the published image runs nginx on port 8000 inside the container, in front of uvicorn):
docker run -d --name proxbox-api -p 8800:8000 emersonfelipesp/proxbox-api:latest
HTTPS with mkcert (optional): the backend also publishes emersonfelipesp/proxbox-api:latest-mkcert (and :). nginx terminates TLS there (mkcert certs) on PORT (default 8000); add more certificate names or IPs with MKCERT_EXTRA_NAMES (comma- or space-separated). Example:
docker run -d --name proxbox-api-tls \
-p 8800:8000 \
-e MKCERT_EXTRA_NAMES='proxbox.backend.local' \
emersonfelipesp/proxbox-api:latest-mkcert
Point your NetBox ProxBox API endpoint at https:// (or your mapped port). Trust the mkcert root on clients if needed; see the proxbox-api README for build flags, CAROOT, and details.
- Configure endpoints in NetBox:
Datastore.Audit,
Sys.Audit, VM.Audit, VM.Monitor, and VM.GuestAgent.Audit.
VM.GuestAgent.Audit is required on Proxmox VE >= 9 for the backend to
pull VM IPs through the QEMU guest agent — without it, VMs sync but
their IP addresses are missing from NetBox. See the proxbox-api docs
Required Proxmox role privileges
for the pveum role add command.
- Create a NetBox API endpoint (your NetBox URL and token)
- Create a ProxBox API endpoint (the backend from step 4)
- Run your first sync:
NetBox Docker Install Option
If your NetBox runs with netbox-community/netbox-docker, install the plugin through the Docker plugin files in your NetBox Docker project:
- Add plugin requirements to
plugin_requirements.txt(PyPI or Git):
netbox-proxbox
# or
# netbox-proxbox @ git+https://github.com/emersonfelipesp/netbox-proxbox.git
- Enable the plugin in
configuration/plugins.py:
PLUGINS = ["netbox_proxbox"]
- Rebuild and restart NetBox:
docker compose build
docker compose up -d
- Run migrations in the NetBox container:
docker compose exec netbox /opt/netbox/netbox/manage.py migrate
For complete Docker installation instructions, validation checks, and Git/source install examples, see docs/installation/3-installing-plugin-docker.md.
Scheduled Sync
Proxbox sync jobs run on NetBox's default RQ queue. A standard NetBox installation already ships a netbox-rq systemd service that runs:
manage.py rqworker high default low
Check whether it is running before doing anything else:
sudo systemctl status netbox-rq
If it is active (running), you have nothing extra to configure — Proxbox jobs will be picked up automatically.
If the service is inactive or missing, enable it:
sudo systemctl enable --now netbox-rq
The unit file is provided by NetBox at contrib/netbox-rq.service in the NetBox repository. If you need to create it manually, copy it from there and run:
sudo systemctl daemon-reload
sudo systemctl enable --now netbox-rq
Upgrading from an older Proxbox release? Jobs used to be enqueued on thenetbox_proxbox.syncqueue. The stocknetbox-rqservice does not listen to that queue, so old-style jobs will not run. New jobs always usedefaultand are picked up without any changes.
Disabled ProxmoxEndpoint rows are hard-excluded from operational reads and
sync jobs. The scheduler, CLI sync command, dashboard cards, keepalive checks,
HA/storage/firewall/SDN/datacenter live reads, backend endpoint preflight, and
stale scheduled job parameters all filter to enabled=True before contacting
proxbox-api or Proxmox. To pause a production endpoint, set Enabled to
false; the row remains visible in the API and UI but no connection attempt is
made for that endpoint.
Schedule a sync
- In NetBox, go to Proxbox > Schedule Sync.
- Choose one or more sync types (All, Devices, VMs, Storage, etc.).
- Optionally set a Schedule at time and a Recurs every interval in minutes (e.g.
1440for daily). - Click Schedule.
Job timeout
Proxbox sync jobs default to a 7200-second (2-hour) RQ wall-clock limit (PROXBOX_SYNC_JOB_TIMEOUT). NetBox's default RQ_DEFAULT_TIMEOUT is only 300 s, which would kill long syncs. No configuration is needed unless your syncs routinely take longer than two hours; if they do, override the constant in netbox_proxbox/jobs.py.
Troubleshooting
| Symptom | Likely cause | Fix |
|---------|-------------|-----|
| Job stays pending | No RQ worker running, or worker not listening to default queue | Start/restart manage.py rqworker |
| Job stays running for a long time | Proxbox API is still syncing or stream is slow | Check the job Log tab; wait or inspect the backend |
| Job errored: JobTimeoutException | RQ wall-clock limit exceeded | Increase PROXBOX_SYNC_JOB_TIMEOUT in netbox_proxbox/jobs.py |
| Disabled endpoint still appears in /api/plugins/proxbox/endpoints/proxmox/ | Expected API behavior; disabled rows remain inventory records | Leave it disabled to prevent all connection attempts. Re-enable only when the endpoint should participate in cards, checks, and sync jobs again. |
| VM IP addresses stay empty after upgrade | The separate proxbox-api backend is too old, is on the v0.0.13/v0.0.14 agent-flag warning window, existing VMs still lack proxmox_vm_id, or the Proxmox role lacks guest-agent privileges | Check the FastAPI card warning on the Proxbox home page. Run proxbox-api >= 0.0.13 at minimum; if the warning references PR #156, install a backend build containing that fix or the next fixed backend release. Then run Full Update so existing VMs get proxmox_vm_id before the IP-address stage runs. For PVE 9, also confirm VM.GuestAgent.Audit. |
| HTTP 401 Authentication failed! against Proxmox VE 9.x | A stale stored token is overriding fresh password credentials, or the role is missing PVE 9 permissions | On the Proxmox endpoint edit page, tick "Clear stored API token on save" (and/or "Clear stored password on save") to wipe the unused secret. The form rejects rows that end up with neither a password nor a complete (token name, token value) pair. Confirm the role on Proxmox grants Datastore.Audit, Sys.Audit, VM.Audit, and on PVE 9 also VM.GuestAgent.Audit. The plugin now surfaces the upstream PVE 9 error message in the UI instead of "Unknown error.", which makes "no such realm" / "expired token" / "missing privilege" failures self-diagnosing. |
Switching credentials cleanly (PVE 9 friendly)
The Proxmox endpoint edit form preserves the stored password and token value
when you submit blank masked fields — that is intentional for partial edits.
When you genuinely want to switch auth modes (for example, password → token
or vice versa, or rotate a leaked secret), tick the matching **"Clear
stored …"** checkbox so the unused credential is wiped on save. Clearing the
token always clears both token name and token value together so the row
never persists in a half-token state.

LLM Agent Safety
Before any destruction-adjacent operation, read AGENTS.md §"LLM Agent Safety Guardrails".
Proxbox protects VM destruction behind a five-lock chain. LLM agents MUST NOT:
- Autonomously set
apply_destroy_confirmed=True - Submit the confirmation phrase
"allow-edit-and-add-actions"on a user's behalf - Approve a
DeletionRequestas the same user who created it (self_approve_allowed=False)
DeletionRequest REST endpoint (/api/plugins/proxbox/deletion-requests/) is read-only — enforced by netbox_proxbox/api/views.py::DeletionRequestViewSet.http_method_names = ["get", "head", "options"]. Pinned by tests/test_static_guardrails.py.
The plugin contains a read-only semantic producer manifest for a future
compatible netbox-sdk bridge. No
released SDK identity is activated yet: the checked activation artifact remains
blocked, so the API root omits mcp and /api/plugins/proxbox/mcp/ returns 503
until one exact immutable SDK passes the paired CI vectors. The future
bridge exposes sync-job listing and guarded scheduling through the existing DRF
endpoint; the plugin does not run a separate MCP server or store a second
credential.
Scheduling is advertised as destructive because reconciliation can remove
stale NetBox inventory records, not because it deletes Proxmox infrastructure.
Once activated, agents use netbox-sdk's generic plugin_list_tools and
plugin_call_tool envelope; the descriptor names are not standalone MCP tools.
Bridge v1 accepts
13 explicit concrete sync_stages, an optional fail-closed Proxmox endpoint
scope, strict RFC 3339 scheduling, and an exactly-one-unit bounded recurrence.
It does not expose the legacy REST netbox_endpoint_ids scope. The MCP
mutation opt-in is server-wide, not per tool, and ambiguous write outcomes must
never be auto-retried. Integer JSON endpoint-ID literals retain the full signed
64-bit range, while integral float/Decimal forms normalize only through
9007199254740991 to prevent rounded identity. The complete discovery flow,
executable examples, error handling, compatibility policy, and agent checklist are in the
Semantic MCP Bridge guide.

Gitea pull-request CI runs the quality/mocked suite before strict docs/package
validation on the shared capacity-bounded Python runner. One repository-wide
concurrency group covers all refs without auto-cancelling protected or immutable
evidence. Both jobs require at least 384 MiB free and print the measured and
required KiB before environment creation. That floor is based on a 195,498 KiB
locked quality environment plus the 42,021 KiB source tree, leaving 155,697 KiB
of measured residual capacity before transient operations. The hosted preflight
reports the exact available capacity; serialization and cacheless operation
bound the remaining pressure. Both jobs set UV_NO_CACHE=1 and always
remove environments, tool caches, output trees, and generated bytecode. Quality
installs the locked test, dev, and cli optional extras with --no-dev;
the serialized docs job owns the separate MkDocs dev and exact packaging
publish dependency groups and builds without an isolated floating tool
environment. Keep those scopes separate so concurrent caches, duplicate docs
dependencies, or floating package tools cannot exhaust or drift on the runner.
Each job also scrubs those paths before use; stale generated-state symlinks are
removed without traversal and fail that run closed, protecting reused workspaces
from redirected writes or stale package evidence.
