Hello.

I'm wo= =3D ndering if it is possible to create VMs with ovirt that have scsi disks?

I've just installed ovirt 3.2.1 on Fedora 18 and attached an ovir= =3D t node (the current fedora 18 based version).

= =3D

= =3D When adding disks to a VM I can chose from the 'IDE' or 'VirtIO' interfaces= =3D . I'd like a scsi option also.

Mainly because when migrati= =3D ng from vsphere VMs this makes things simpler.

Also, my current= =3D kickstart installer for various OSes does not yet handle 'vd' disks.

To add to things I need to install a custom filesystem on the vms th= =3D at wants a scsi disk. It does a scsi inquiry early on in the install = =3D phase and will not work in 'vd' disks. ie: 'sg_inq /dev/vda' d= =3D oes not work.

I also know that the libata driver in recent linu= =3D x distributions exposes IDE drives as scsi and allows a scsi enquiry to suc= =3D ceed. Unfortunately the use case I have required Enterprise Linux 5 a= =3D nd in this release IDE disks report as 'hd', whereas scsi disks report as '= =3D sd'. So, I can just use an IDE disk to get around this problem.

I understand that virt-manager will allow attaching scsi disks to KVM bas= =3D ed virtual machines, and that this is made possible by recent changes in libvirt.

I think we should be encouraging people to use the virtio disk= =3D s where possible, but in cases where this is not straightforward ovirt - an= =3D d RHEV - are missing a trick as far as allowing people that have existing v= =3D sphere setups to fairly easily move to ovirt.

Is a 'scsi' interface' opt= =3D ion for adding virtual disks for VMs on the roadmap? If not, could it be considered?

Thanks.
