That wasn't listing supported archs from libvirt compilation, it was instead
refering to the capabilities APIs. So it was listing archs that might be 
supported by the current hypervisor connection. eg, the archs that might be 
returned by a call to


So with Xen on x86_64, it'd list  'x86_64' and 'i386', for Xen on i64 it'd
list 'ia64', for QEMU it'd list  i386, x86_64, ppc, sparc.

For Xen we're basically pulling the info out of 


We've already got ia64 support there - including a number of test cases to
verify correct parsing
