Network interfaces names question

[rimvydukas]

Hi,
I've created following network setup:

iface eno1 inet manual
iface eno1.191 inet manual

auto vmbr191
iface vmbr191 inet static
address 192.168.0.1/24
bridge-ports eno1.191
bridge-stp off
bridge-fd 0

I can see vmbr191 interface after proxmox restart. But when I start VM one more additional interface appears - vmbr191v19

Can someone tell me more about this interface? I thought that it is VM's interface, like vnet in KVM, but it seems its not. So I'm little bit lost here

To create a bridge, bound to a shared-by-other-VLANs physical interface and connecting to VLAN #2 (so VMs don't know that this is a VLAN) I have stanzas like this:

iface enp1s0 inet manual

auto vmbr2
iface vmbr2 inet manual
        bridge-ports enp1s0.2
        bridge-stp off
        bridge-fd 0

Note that I do not have something like "iface eno1.191 inet manual". The assignment to VLAN number 2 is in "bridge-ports enp1s0.2". My example has no IP address, but adding one does work.
