I am running into stability issues with some windows guests on an openstack setup, and one of the suggestions in the qemu bug site was to provide the "+hv_relaxed" parameter to the CPU (https://bugs.launchpad.net/qemu/+bug/992067)

Is there a way I can tell nova to somehow use this parameter? I haven't been able to find a way.

Thanks.

Nova doesn't provide a facility for passing arbitrary arguments to qemu-kvm. Taking advantage of the, relatively new, functionality in qemu-kvm for setting +hv_relaxed and other relevant flags for recent Windows guests will require changes to Nova to detect (or be told) the guest operating system in use and set the flags accordingly.
