Troubleshooting: Windows Guest on KVM

While migrating windows virtual machine from virtualbox to kvm you might experience an issue related to significant virtual hardware changes, in other words you get BSoD (bluescreen). Here are few findings that can help you:

1. Windows 2003, BSoD. STOP: 0x0000007B. Here is a description. You need apply this before you convert image to kvm.
2. Error message that computer does not have a parallel port: "The Parallel port driver service failed to start". Read more here.
3. If your Windows host was configured in KVM configuration first choose IDE drive as disk bus, add SCSI controller. When guest starts let it scan for hardware changes, that might take few minutes, when it finds SCSI controller shutdown guest and change disk bus to use SCSI controller, you can remove IDE controller.
4. Uninstall virtualbox guest tools, so windows doesn't complain (see system event log).

The above "fixes" should let you start your windows guest in kvm.
