Version 0.0.23

netbox-proxbox 0.0.23 pairs with a proxbox-api
guest-VM-interface writer build / next release (the guest_os_model VM
interface sync strategy),
alongside proxmox-sdk 0.0.12 and netbox-sdk 0.0.10. NetBox compatibility is
unchanged: 4.5.8 through 4.6.99 (validated against 4.5.8, 4.5.9, and
4.6.0 through 4.6.4).

Current 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.

Highlights

• Dual VM interface sync (new standard). Proxmox reports NICs as net0,
  net1; the QEMU guest agent reports OS names such as ens18, eth0.
  Previously the guest-agent name renamed the single core VMInterface, which
  was lossy and broke IP-to-interface matching for VMs whose OS names differ
  from the Proxmox config names. The new default keeps the Proxmox NIC as a
  core virtualization.VMInterface with its canonical name (net0) and
  records each guest-OS interface as a new GuestVMInterface plugin object,
  mapped one-to-one to the core interface by MAC address. Both point at the
  same ipam.IPAddress object through GuestVMInterfaceAddress — the IP is
  never duplicated.
• New setting vm_interface_sync_strategy. guest_os_model (the new
  default) enables the behavior above. legacy_rename reproduces the previous
  single-interface rename behavior and is retained for backward compatibility
  but deprecated; the use_guest_agent_interface_name toggle now applies
  only under legacy_rename.
• New REST endpoints. /api/plugins/proxbox/guest-vm-interfaces/ and
  /api/plugins/proxbox/guest-vm-interface-addresses/, with list views,
  filters, and navigation under Virtualization.
• Data-integrity guards. GuestVMInterface.vm_interface is a one-to-one
  link with SET_NULL (guest inventory survives core-interface churn).
  GuestVMInterfaceAddress validation guarantees the linked IP is the same
  object assigned to the mapped core interface (or, for agent-only interfaces,
  on the same virtual machine), preventing cross-VM or foreign-object IP links.

Compatibility and upgrade notes

NetBox	netbox-proxbox	proxbox-api	netbox-sdk	proxmox-sdk
>=4.5.8	v0.0.23	guest-VM-interface writer build / next release	v0.0.10	v0.0.12
>=4.5.8	v0.0.22	v0.0.19.post5	v0.0.10	v0.0.12

• Backend requirement. The guest_os_model behavior is populated by
  proxbox-api with the matching guest-VM-interface writer. Against an older
  backend, the core VMInterface/IP sync is unchanged and the guest objects are
  simply not written.
• Upgrade behavior. Migration 0059 is additive. Existing installs
  (detected by the presence of a configured Proxmox endpoint) are backfilled to
  legacy_rename so an upgrade never silently changes interface naming;
  operators opt into guest_os_model explicitly. Fresh installs default to
  guest_os_model.
• Addresses the long-standing "IP addresses not syncing / net0 vs ens18"
  reports.
