Xen HVM is actually faster than Xen PV for some workloads.. it really depends on the workload.
(And vice versa; for some workloads Xen PV is faster than HVM).
If the workload consists of...

Xen ACPI cpufreq patches
The power consumption differences are explained by the lack of Xen dom0 ACPI cpufreq patches in the current upstream Linux kernel v3.x. This was already pointed out earlier in the comments for the...
