For PV, Xen implements the <clock offset='utc'> and <clock offset='localtime'> behaviour, while for HV it implements <clock offset='variable'>. This difference is important for domUs, which switch daylight saving on there own, since the state is kept inside the VM and must be in sync with the RTC provided by Xen.
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
