Hi there!
If we have Wireless devices like WiFi cards, doesn''t a Xen hypervisor
support it just as a regular OS will support it with same drivers? Anything
different in this case compared to non-virtualized case?
Regards!

Also note the the Xen Linux Kernel (2.6.18.8) may not contain the "latest and greatest" wireless drivers, so you may want to have a look at one of the forward ports available for your favorite distribution...

I wonder what would be involved in making a single WiFi card maintain several associations with the access point... one for each bridged device?
