Thanks for your feedback. Is there also a /usr/lib64/xen-default? Having
the version numbers in there is a recipe for disaster. If so I'd cook up
a patch for libvirt. I think virtinst should pick up the path from there
then.
I don't have a xen system here but the search on packages.debian.org
doesn't show a package containing /usr/lib64/xen-4.0/bin/qemu-dm in sid.
Cheers,
