I confirm that I have encountered this also and resolved in in same manner. On Thu, Mar 21, 2019, 21:11 <jingjie.jiang@oracle.com> wrote:

1. create Windows guest from oVirt 4.2.8 env with IDE virtual disk interface 2. follow the instruction from https://community.redhat.com/blog/2015/05/how-to-install-and-use-ovirts-wind... installed the virtio drivers and ovirt guest agent. 3. Shutdown Windows guest and switch the virtual disk from IDE to virtio-scsi 4. Run the Windows guest and it boot up fine. 5. Shutdown Windows guest and switch the virtual disk to virtio 6. Run the Windows guest but it failed to boot up.

7. Switch the boot disk to virtio-scsi and attach another virtual disk as virtio to Windows guest 8. Boot the system up and make sure that viostor driver is installed. 9 switch the boot virtual disk interface to virtio. 10. Boot the Windows guest and it boot up OK.

I was wondering the installer of virtio drivers cover the case of install vioscsi driver even without virtio-scsi device but not for virtio device. Would the dev-team mind confirm?
