I managed to r= eproduce it only once after reboot and it grubs CPU for only minute or two = while i checking it and than returned to normal CPU usage. I've checked bot= h distribution and the trunk version. So suspend this bug until someone can stably reproduce it. -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1174654 Title: qemu-system-x86_64 takes 100% CPU after host machine resumed from suspend to ram Status in QEMU: Confirmed Status in =E2=80=9Cqemu=E2=80=9D package in Ubuntu: Confirmed 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 stucked on some single process.
