Hi guys,

I deployed my 3rd node of proxmox VE in my cluster now and I get an error on starting and LXC after restoring it from backup/migrating it from an other node/creating a completly new LXC.

The error looks like this:
Rich (BB code):
netdev_configure_server_veth: 661 Operation not supported - Failed to create veth pair "veth106i0" and "veth30HjTl"
lxc_create_network_priv: 3413 Operation not supported - Failed to create network device
lxc_spawn: 1837 Failed to create the network
__lxc_start: 2068 Failed to spawn container "106"
TASK ERROR: startup for container '106' failed

the vmbr2 was only created for testing because the same error happened to me on vmbr0 (the default vmbr that was created during initial setup). So the vmbr couldn't be the issue in my opinion. I already tested it without the VLAN aware setting.

I'm running PVE 7.1-10.

I hope someone can help me here :/
