I'm afraid virt-manager doesn't support installing VMs connected to VLAN
interfaces at this time. I'd like to get support for doing this in the UI
but I don't have a network with VLANs so can't test. If anyone wants to
contribute patches to make it work I'd welcome them. Its mostly just a
problem of figuring out how to enumerate the list of bridges attached to
VLAN interfaces. 

In the meantime the best workaround I can offer is to use  virt-install
command line for installing the VMs initially. This lets you explicitly
enter a bridge name as a command line flag.

Dan.
