KVM hypervisor with VLAN

Hi, how to tune KVM if all Virtual machines must be connected by Virtual Switch with VLAN?
All IPs in my case is external, NAT is not need, and Virtual Switch connected to the same network interface as main interface.

Solved, need ordinary configure VLAN, then use MacVTap in VM, and no need NAT or bridge at all.

That’s great Alix.
