Description Michal Skrivanek 2016-11-28 12:04:51 UTC

For years we support virtio-scsi in parallel to the older virtio-blk interface. SCSI is now more mature, has more features, negligent performance penalty in the worst case, and is stable enough to become the preselected default.

We still want to support both, but virtio-scsi is already a better choice, let's help uninformed users to use the right one. 

Should be enough to modify Blank template and Add Disk dialog

The fix for this issue should be included in oVirt 4.1.0 beta 1 released on December 1st. If not included please move back to modified.
