[Engine-devel] Issues with VirtIO-SCSI

[Vitor de Lima]

Hi everyone,

I have found some issues with this patch:

http://gerrit.ovirt.org/#/c/18638/

It allows the user to disable the VirtIO-SCSI disk interface during the VM creation. The problem is that the user still can add, attach and hotplug disks with the VirtIO-SCSI interface type, but when the user does so, libvirt automatically creates a LSI Logic SCSI controller and connects the new disk to it.

How can this problem be solved? Should the VirtIO-SCSI interface type be hidden from the user in case it wasn't enabled, or should the engine enable the VirtIO-SCSI controller, hotplug it, then hotplug the disk into it transparently?

Thanks,
Vitor de Lima
