I was seeing this problem when my Debian laptop suspended. The CentOS
guest would begin consuming a lot of cpu and only a hard-reset would fix
it.
Changing the rtc line to
<timer name='rtc' track='guest'/>
seems to have fixed it, though I haven't done extensive testing yet.
Thanks!

Title:
qemu-system-x86_64 takes 100% CPU after host machine resumed from
suspend to ram
Status in QEMU:
Confirmed
Status in qemu package in Ubuntu:
Invalid
Bug description:
I have Windows XP SP3 inside qemu VM. All works fine in 12.10. But
after upgraiding to 13.04 i have to restart the VM each time i
resuming my host machine, because qemu process starts to take CPU
cycles and OS inside VM is very slow and sluggish. However it's still
controllable and could be shutdown by itself.
According to the taskmgr any active process takes 99% CPU. It's not
stuck on some single process.
