I am running Ubuntu Wily (the 20150717 daily build) can reproduce this
problem, whatever the guest is Linux or Windows, after host got resumed
from suspend, the kvm (qemu-system-x86_64) process becomes a 100% cpu
usage,
user@ubuntu-mate:~$ kvm --version
QEMU emulator version 2.3.0 (Debian 1:2.3+dfsg-5ubuntu2), Copyright (c) 2003-2008 Fabrice Bellard
I wonder can the kvm program be fixed?

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.
