Only PV is supported right now, although there have been two efforts in the 
past.

Jon Ludlam posted some patches for an HVM MiniOS, but there have been 
significant changes in it since (ARM support, and a separate upstream) that it 
will need some work to re-adapt.

Martin Lucina has got a version of Mirage that builds using Rumprun, which 
requires a bit of cross-compilation.  The resulting kernel boots as HVM, but 
the patches haven't been inlined yet.

What's your Xen/HVM usecase?  Is it a cloud provider that only supports it, or 
some other reason why PV boot isn't enough?
