[Users] info on virtio-scsi
Hello, I had a CentOS 6.4 VM created in oVirt 3.3.0 Then I updated to 3.3.1 I created a CentOS 5.10 VM In CentOS 5.10 I built rhev-agent-2.3.16-3.el5.src.rpm In CentOS 6.4 I have ovirt-guest-agent-1.0.8-1.el6.noarch Both are configured with one virtio disk. In CentOS 5 I can add a disk and select virtio-scsi... but I can't use it because of no support in 5.x kernels. In CentOS 6.4 I'm not presented with the option virtio-scsi. What can I do to get it?

did you do a clean install of the guest OS to a virtio-scsi disk?

As I wrote above, both installed with only one disk as virtio. C5 right after update to 3.3.1 C6 before. Both powered on. In c5 I have chance to add virtio-scsi in drop down menu (even if then I cannot use it due to missing driver it seems); in c6 I only have ide and virtio...

oh, that's strange. derez/roy - no virtio-iscsi definition for .el6 VM?

Actually I don't think so. I have tried creating a new rh el 6.x x86_64 vm and at disk creation I do see virtio-scsi as an option. But for this preexisting VM I don't see it when I try to add. Tried both in powered on state and in powered off. See here difference between c6 and c5 dynamic xml in /var/run/libvirt/qemu https://drive.google.com/file/d/0BwoPbcrMv8mvemtSalRkTTZlV1k/edit?usp=sharin...

I found it! By default now when I create a VM, I can see that in advanced parameters --> Resource Allocation I have virtio-scsi enabled. Instead for pre-existing VM it wasn't. I tested editing the VM while powered on and then I was able to add and activate a virtio-scsi disk.
