Vmbr0 should be your VLAN aware bridge. You create this in the pve networking dashboard.

Then create vmbr0_101 (where 101 is your vlan). Also create vbmr0_102, and so on.

Assign those vmbr0_xxx to each of the VMs.

If you host all the VM’s on the same box, create all the vmbr0_xyz in the pve dash, and in each VM/container>networking assign it.

Do a search for ‘Lm-sensors proxmox’

Its proprietary though, right?
