I am curious about the same thing. <div>Is it possible to setup libvirt to have different VMs on the same phyiscal NIC on the same physical machine to run under different VLAN? My understanding is that VLAN is setup on the switch for each physical port.</div>

I was hoping I could use network contextualization as a way to configure the guest's 802.1q tags.</div><div>I guess I don't understand vlan tagging when "dom0" bridging is in the mix.</div><div><br></div>
