Disk controller and network card are virtio devices with drivers from https://launchpad.net/kvm-guest-drivers-windows/+download (virtio-win-drivers-20120712-1.iso). -Everything worked fine until I changed disk controller cache from the default (writethrough) to writeback. This introduced occasional blue screens. I noticed that they are linked to high disk IO. For example restoring over 1GB of backup files will results in a blue screen on around 4 out of 5 attempts. Also Windows update crashes the system sometimes. When idle the system will run fine for hours or sometimes even days. -After removing cache='writeback' from the config everything came back to normal. - -qemu-kvm: - Installed: 1.0+noroms-0ubuntu14.8 - Candidate: 1.0+noroms-0ubuntu14.8 - Version table: - *** 1.0+noroms-0ubuntu14.8 0 - 500 http://archive.ubuntu.com/ubuntu/ precise-updates/main amd64 Packages - 100 /var/lib/dpkg/status - 1.0+noroms-0ubuntu14.7 0 - 500 http://security.ubuntu.com/ubuntu/ precise-security/main amd64 Packages - 1.0+noroms-0ubuntu13 0 - 500 http://archive.ubuntu.com/ubuntu/ precise/main amd64 Packages \ No newline at end of file |
