This has been asked before but not answered, so I need to ask again:
My setup looks like this:
![]()
vm1 and vm3 should have two ethernet ports, being able to access vm2 and vm4. I was wondering if I could simply assign an IP address (venet) plus a network card connected to a bridge (veth) but this does not work as expected: Proxmox VE 2.2 gives me an error 130 (500) when I try to add a veth device after an IP address has been assigned.
How should I create this? Any help is appreciated. Kind regards,
Christian
Can a container have both a venet IP address as well as a veth network interface? Or: Do I even need that?
