Problem was in 13.04 but it's also still = there in 13.10. The windows guest has virtio / spice enabled. Linux guests do not get the high cpu usage. Are there any more logs required or is investigation going on upstream ? I am not sure where to look or curious whether there are other workarounds. ** Attachment added: "win7.xml" https://bugs.launchpad.net/qemu/+bug/1174654/+attachment/3875634/+files/= win7.xml -- = 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: 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.
