Actually the origin of the bug could indeed be facter.

If you look at the virt-what resolver [0], it's just matching for 
strings in the output. If the output of virt-what contains both 
'xen-hvm' and 'xen-dom0' then 'xenhvm' is going to be used because 
'xen-hvm' will match first. It's possible we might want to actually 
match for 'xen-dom0' *first*, but this all depends on virt-what's full 
output.

Would it be possible to share here what virt-what is outputting both on 
dom0 and domU?

Thanks,

-- Jérôme
