Not entirely. There are several "tricks" you can use to get networking from wifi to a guest. VMWare (Workstation) uses NAT by default, turning your computer into a gateway router and creating a virtual bridge. This can be done in linux, just google "iptables nat".

You could also (in theory, at least) pass your wifi card hardware through to the guest. It would only allow one guest to connect at a time, but this may be acceptable ib your use case, I don't know. 

If you need more help with Xen configuration, there is a very helpful Xen mailing list called xen-users. You'd get more Xen help there than on arch-general, I think.
