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

[Serge Hallyn]

Thanks for reporting this bug.  I won't be able to test this for another
week or two (waiting on a license).  Would it be possible for you to
test with the latest upstream git?

        sudo apt-get install git
        git clone git://git.qemu.org/qemu.git
        cd qemu
        ./configure x86_64-softmmu
        make
        cd x86_64-softmmu
        sudo mv /usr/bin/qemu-system-x86 /usr/bin/qemu-system-x86.orig
        sudo cp x86_64-softmmu /usr/bin/

Then re-test your guest.

If that's not possible then please let us know.

Title:
  qemu-system-x86_64 takes 100% CPU after host machine resumed from
  suspend to ram

Status in QEMU:
  Incomplete

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.
