[Qemu-devel] [Bug 1174654] Re: qemu-system-x86_64 takes 100% CPU after host machine resumed from suspend to ram

I don't know if this will help, but I had a similar problem.
When creating a snapshot image of an XP machine, all works just fine
when loading it. As time passes on the host the loadvm start to become
1. Create a snapshot image (savevm)
2. leave QEMU
3. move the *HOST* clock one month in the future
4. Start QEMU with -loadvm
It turns out that the "-rtc clock=vm" made this disappear. When using
the default caused the problem.

qemu-system-x86_64 takes 100% CPU after host machine resumed from
suspend to ram
Status in QEMU:
Status in “qemu” package in Ubuntu:
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
stucked on some single process.
