I'm not quite sure it's dual licensed, because that would imply that 
someone can recompile their product and get full functionality for free, 
albeit without support.  The free XenServer is still limited to 4GB of 
RAM and 4 VM's per server.  Also from what I can see, XenServer lacks 
the ability to do snapshots, which I really don't understand considering 
they're using LVM.

And actually James has been making great strides with his GPLPV drivers, 
so freeware Xen is catching up to XenServer fairly fast, although it's 
still lacking good GUI tools. 

Hopefully soon James will release version 1.0 of his drivers, and I can 
finally consider using Xen in production.
