Is your feature request related to a problem? Please describe.
Discovery does not identify VM/LXC bridges in Proxmox (or any Linux host). As a result Virtualization mapping is manual.

Describe the solution you'd like
ip addr show provies the list of interfaces that could be mapped to VM/LXC hosted on Proxmox. Similar to how Docker bridges are auto-discovered.

Describe alternatives you've considered
I manually assign VMs to hosts. But this does not get updated when containers are migrated to another host in a Proxmox Cluster.
