I tried to isolate the VM of PROXMOX VM 7.2 using VLANs. Every VM has its own VLAN.
But for unite many VLAN to one ip subnet with real ip address I try to use Private VLAN with switch VDX-6720 NOS 4.1.3a.
In private-vlan trunk host mode all works ok, on the server side it is seen as PRIMARY VLAN...
