I'm pretty certain this is a bug in libvirt, introduced by this patch:

http://www.redhat.com/archives/libvir-list/2007-April/msg00078.html

I think Dan's probably the best one to tell us what's going on here, but 
from my understanding the patch above is wrong and should have instead 
added this:

#ifndef DOMFLAGS_HVM
#define DOMFLAGS_HVM (1<<1)
#endif

//...

#ifdef DOMFLAGS_HVM
domain_flags &= ~DOMFLAGS_HVM; /* Mask out HVM flags */
#endif

I think if the Xen driver can be correctly built then you won't need the 
proxy.
