[Users] EL5 support for VirtIO SCSI?

[Paul Jansen]

Hi Rene.
I specifically need the scsi support (virtio-scsi).
I do know about the virtio-block support, which results in /dev/vd* devices as you say.
From what I read even EL6 earlier than 6.3 does not support virtio-scsi

Alternatively, does oVirt support an emulated scsi adapter of a different type that would allow me to see scsi disks?

Regards,
Paul

If you're installing the OS on a VirtIO disk this is done automatically
by anaconda. I just installed RHEL 5 on oVirt 3.3 with VirtIO disk and
everything worked out of the box.

There's no /dev/sd* device - the devices are named /dev/vd*...

Didn't test CentOS but RHEL 5 is working fine.
