Hi Peter,

we run into same trouble and got some hints from TUV (we have some RHEL systems
with support). There is a ticket open in TUV's supports about the issue.

Try the following clock settings for your Windows VM's:

  <clock offset='localtime'>
    <timer name='rtc' tickpolicy='catchup'/>
  </clock>



Sincerly,
Klaus
