[Qemu-devel] [Bug 1308341] Re: Multiple CPUs causes blue screen on Windows guest (14.04 regression)
Tue, 20 May 2014 13:13:29 -0000
After adding "hyperv" feature, the guest freezes regularly. This happens
on both and Windows 7 64-bit and Windows 2012 R2 guests. When removing
the "hyperv" feature the guest acts normally, but fails with a blue
screen as before. This may be a completely different issue, but this
renders the workaround unusable for me at least.

Multiple CPUs causes blue screen on Windows guest (14.04 regression)
Status in QEMU:
Status in “qemu” package in Ubuntu:
Status in “virt-manager” package in Ubuntu:
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
"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
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
