What versions of Xen is that true for ?
I tested xen-3.4 and 4.1 and had a short look at 3.2, which all seemd
to have that behaviour.
I didn't think that old
versions behaved this way for HVM. The libvirt Xen driver is still
intended to support the RHEL5 vintage Xen code (which is based on
3.0.3)
I'll try to install RHEL5 and take a look, but not before friday.
Sincerely
Philipp
