Virtio SCSI driver not working for Windows 2003
Last modified: 2015-09-22 09:09 EDT
Description of problem:
The Virtio SCSI driver is installed (and correctly reported via Guest Agent), but after adding new Virtio SCSI disk, this disk is still not seen by Windows 2003 machine
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Have VM with Windows Server 2003 R2 64 bit
2. Install Guest Tools using installer
3. Shutdown VM and add new Virtion SCSI disk
4. Start VM, run Disk Management
the disk is still invisible to the VM
the disk should be visible
version of the driver?
lev - did you see something similar? is it an install issue or should be moved to kvm group?

I tested it with Windows Server 2003 R2 Standard 64 bit (Build 3790.srv03_sp2_rtm.070216-1710 : Service Pack 2) , and I had no issues with either installing the driver as part of the Windows Guest Tools, or having a new drive being recognized.
As matter of fact I was even able to add a new disk while the OS was up and running, even though the recognition of the new disk is not instant like it normally happens under Windows 7 for instance, but takes about a minute to become recognizable to OS (through Rescan Disks of Disk Management).
Even without any Virtio-SCSI drives attached to the VM, the Virtio-SCSI Controller should be visible to the OS, as the device is normally created for all VMs under RHEV 3.3.
Before the driver installation it appears as SCSI Controller, and after the driver is properly installed it must appear as Red Hat VirtIO SCSI pass-through controller, under SCSI and RAID controllers in Device Manager.
Do you see it there ? Does it have a properly installed driver ?
wasnt able to reproduce on the newest is, marking as not a bug to avoid confusion
