Description of problem: After installing the PV drivers, I have 2 boot disk instances. One is QEMU and the other is RHEL SCSI. Version-Release number of selected component (if applicable): Windows 2008 64 bit SP1. How reproducible: only once so far. Steps to Reproduce: 1. Create and install Windows 2008 64 bit guest. 2. Install PV drivers. 3. reboot. Actual results: There are now to instances of the boot disk. The QEMU instance is the live instance. The RHEL SCSI instance can not be accessed but shows up in Device Manager and Storage Management. Expected results: The boot disk should be RHEL SCSI. Additional info:
the xenpv drivers are not supported for boot disks by design. You can only set secondary (data) disks to use the xenpv (RHEL SCSI) drivers. The boot disk for Windows must be left as an IDE disk.
On Windows 2000, Windows XP and Windows 2003 all the disks are RHEL SCSI disks after the PV drivers are installed. We start the boot disk as a QEMU disk then it changes to a RHEL SCSI disk. I'm not sure how this magic works but it does. Secondly, If we want the boot disk to remain QEMU, we shouldn't have a second instance of the disk as a RHEL SCSI device. There is a bug here somewhere.
