[Bug 1308341] [NEW] Multiple CPUs causes blue screen on Windows guest

[Hein Gustavsen]

Public bug reported:

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
