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 ** Affects: qemu-kvm (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1308341 Title: Multiple CPUs causes blue screen on Windows guest To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/1308341/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
