Good day.
sorry if i got you guys confused.
for clarity:

i have a server with two nic, currently one nic is connected to public
network and the other one is disconnected.

And i have a vm that will be the firewall of other vm inside this
standalone/selfhosted ovirt.

then i am figuring out how can i pass the vlan ids on the vm or is it
possible.
