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 a= llocated 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.
