QEMU accessing VLAN

[Andrew Wood]

I've got a host with some QEMU virtual machines on it, the host did have 
just one IP address (untagged VLAN) on eth0, Ive now added a second IP 
on VLAN 2 (eth0.2). The host machine is working fine but a QEMU VM is 
not able to access anything on VLAN2.

Im using the default setup whereby QEMU provides NAT. Do I need to alter 
the VM config somehow. I was expecting it to pass packets up to the host 
and the host to recognise which interface it was for and route it out 
accordingly. Obviously Im  missing something. Can anyone advise me please?
