When I list the network interfaces on Proxmox server, it shows me several intefaces like eth0, vmbr0, then anothers that I need to know from which VM/CT it is.
fwbr115i0
fwbr130i1
tap123i0
tap124i0
veth164i1
veth168i1
vmbr0v301
vmbr0v306

How can I discover this?

Thanks!
 
Hi,

The VMID and network device config ID are encoded in those names: <type><VMID>i<netdevID>

For example
fwbr115i0
This is a firewall input bridge for the first NIC of VMID 115

This is the TAP device for VM 123 first NIC (net0)
 
Hi,
Do you have a list of NIC types, when they are created and the function of each one?

Thanks!
