This feature request did not get resolved in time for Feature Freeze
for the current Red Hat Enterprise Linux release and has now been
denied. You may re-open your request by requesting your support
representative to propose it for the next release.

Comment 7 Laine Stump 2010-03-26 18:54:23 UTC

libvirt support for the -no-hpet option has been posted upstream:

https://www.redhat.com/archives/libvir-list/2010-March/msg01289.html

In short, to get -no-hpet on the qemu commandline, you would add the following element to your domain's clock element:

   <domain ...
     ...
     <clock ...>
       <timer name='hpet' present='no'/>
     </clock>
     ...

libvirt-0.7.8-0.pre20100330.el6 was built in RHEL-6-candidate with
the patches
