[fedora-virt] Qemu savevm and CPU stuck



Hi,

First post to this list so sorry if I am mistaken.
I've browsed the wiki and googled and could not find anyone having or reporting the same problem.
I am using fedora virt-preview repository on a fedora 11 stable

The savevm/loadvm seems to be slightly broken:

The guest is a Centos5.3

When issuing a savevm in the monitor,
Guest get stuck for a few seconds and I get the infamous soft lockup a couple of time. (see bellow)

The snapshot is working.

When doing a loadvm I often get weird behaviour on the console.
this can be completly removed if I issue a stop and cont before and after the loadvm.


Question is:
Am I doing somthing wrong or is this a bug ?

Thanks
Cheers
Ben
