font-style: normal;"><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: lucida console,sans-serif; background-color: transparent; font-style: normal;">I also know that the libata driver in recent linux distributions exposes IDE drives as scsi and allows a scsi enquiry to succeed. 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'. So, I can just use an IDE disk to get around this problem.<br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: lucida console,sans-serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: lucida console,sans-serif; background-color: transparent; font-style: normal;">I understand that virt-manager will allow attaching scsi disks to KVM based virtual machines, and that this is made possible by recent changes in
libvirt.</div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: lucida console,sans-serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: lucida console,sans-serif; background-color: transparent; font-style: normal;">I think we should be encouraging people to use the virtio disks where possible, but in cases where this is not straightforward ovirt - and RHEV - are missing a trick as far as allowing people that have existing vsphere setups to fairly easily move to ovirt.</div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: lucida console,sans-serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: lucida console,sans-serif; background-color: transparent; font-style: normal;">Is a 'scsi' interface' option for adding virtual disks for VMs on the roadmap? If not, could it
be considered?</div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: lucida console,sans-serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: lucida console,sans-serif; background-color: transparent; font-style: normal;">Thanks.</div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: lucida console,sans-serif; background-color: transparent; font-style: normal;"><br><span></span></div></div></body></html>
