Hmm, I would like to maintain the current behavior for xen < 3.1.0,
since RHEL/CentOS is still a target and I wouldn't want to regress. We
should be able to get this info from libvirt and the ACPI defaults
accordingly, I'll test it out shortly.
As for merging XP 32 and XP 64: the latter is actually more like windows
2003 than it is XP, so it should really remain a separate variant. We
may add more metadata to the osdict in the future that will actually
yeild a difference between XP and XP64. At the very least, back compat
would need to be maintained, so we would need to map the existing
'winxp64' label to something already in the dict.
Thanks,
Cole
