Hello.=0AI'm wondering if it is possible to create VMs with ovirt that have=
scsi disks?=0AI've just installed ovirt 3.2.1 on Fedora 18 and attached an=
ovirt node (the current fedora 18 based version).=0A=0AWhen adding disks t=
o a VM I can chose from the 'IDE' or 'VirtIO' interfaces.=A0 I'd like
a scs=
i option also.=0AMainly because when migrating from vsphere VMs this makes =
things simpler.=0AAlso, my current kickstart installer for various OSes doe=
s not yet handle 'vd' disks.=0ATo add to things I need to install a custom =
filesystem on the vms that wants a scsi disk.=A0 It does a scsi inquiry ear=
ly on in the install phase and will not work in 'vd' disks. ie: 'sg_inq /de=
v/vda' does not work.=0A=0AI also know that the libata driver in recent lin=
ux distributions exposes IDE drives as scsi and allows a scsi enquiry to su=
cceed.=A0 Unfortunately the use case I have required Enterprise Linux 5 and=
in this release IDE disks report as 'hd', whereas scsi disks report as 'sd=
'.=A0 So, I can just use an IDE disk to get around this problem.=0A=0A=0AI =
understand that virt-manager will allow attaching scsi disks to KVM based v=
irtual machines, and that this is made possible by recent changes in libvir=
t.=0A=0AI think we should be encouraging people to use the virtio disks whe=
re possible, but in cases where this is not straightforward ovirt - and RHE=
V - are missing a trick as far as allowing people that have existing vspher=
e setups to fairly easily move to ovirt.=0A=0AIs a 'scsi' interface' option=
for adding virtual disks for VMs on the roadmap?=A0 If not, could it be co=
nsidered?=0A=0AThanks.=0A
