The 192.168.122.0 network is by default configured for host<->guest
connectivity. You probably won't be able to bridge with a wireless
interface anyway. You will be able to do NAT if you like. I can not
recall if the default network is NAT by default, or purely internal.

You shouldn't have to do anything special network-wise. You likely
don't have a network interface on the guest. You'll have to use virsh
and the "attach-interface" command. `virsh help attach-interface` will
give you a bit on useage. I'm not sure if that is hot-pluggable of if
you need to restart the VM.
I've unfortunately been extremely busy this week with an office move,
taxes, and other things. I hopefully will get around to crossing a few
things off my todo list on wednesday:
- Posting my slides
- Updating to Ubuntu's Lucid
- Create a VM with vmbuilder and no network to see how to manually add
On the flip-side, if you have X11, you can use virt-manager, which is
the GUI front-end to libvirt (virsh is the CLI front-end).
