*** This bug is a duplicate of bug 1346917 ***

Same issue there. 2 VMs with 2008 sp2 x86, and 2008 R2 sp1 x64 hanging simultaneously with BSOD stop 0x0000005c (0x0000010b 0x00000003 0x00000000)
Issue arrised after upgrading kernel from 3.12 to 3.13.
Nothing helps to workaround this issue so far.

  Multiple CPUs causes blue screen on Windows guest (14.04 regression)

Bug description:
  Configuring a Windows 7 guest using more than one CPU cases the guest to fail. This happens after a few hours after guest boot. This is the error on the blue screen:
  "A clock interrupt was not received on a secondary processor within the allocated time interval"

  After resetting, the guest will never boot and a new bluescreen with
  the error "STOP: 0x0000005c" appears. Shutting down the guest
  completely and restarting it will allow it to boot and run for a few
  hours again.

  The guest was created using virt-manager. The error happens with or
  without virtio devices and with both 32-bit and 64-bit Windows 7

  I am using Ubuntu 14.04 release candidate.

  qemu-kvm version 2.0.0~rc1+dfsg-0ubuntu3
