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

Status in QEMU:
  New
Status in “linux” package in Ubuntu:
  Confirmed
Status in “qemu” package in Ubuntu:
  Confirmed

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
  guests.

  I am using Ubuntu 14.04 release candidate.

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