Ok found the problem... ... vcpus set to above what is available will
cause lockup for HVM windows vista/2008 (maybe others also) and even
crash your dom0 (happened once and need a hard reboot)!  I forgot
about it as my servers mostly have 4 VCPUS :p  This will not happen if
running xen <3.4.0.

Thanks a lot for all of you who replied especially to Keir who hint me
related to processors type ;)  My stupid overlook on VCPUS value can
cause me headache... ...

Kindest regards,
