Description Yaniv Lavi 2016-03-14 09:27:50 UTC

Description of problem:
Currently, there seems to be no way of changing a disk's interface type.
For example, a disk of 'virtio' interface cannot be added to another VM via the 'virtio-SCSI' interface. This is needed in some cases for DR and backup.

Comment 1 Sandro Bonazzola 2016-05-02 09:48:23 UTC

Moving from 4.0 alpha to 4.0 beta since 4.0 alpha has been already released and bug is not ON_QA.
