Laszlo is right: virt-install \ --name=guest1-rhel64-64 \ --controller type=scsi,model=virtio-scsi \ --disk path=/var/lib/libvirt/images/guest1-rhel6-64.dsk,size=8,bus=scsi,cache=none \ --vnc \ --vcpus=2 --ram=2048 \ --location=http://example1.com/installation_tree/RHEL6.4-Server-x86_64/os \ --network bridge=br0 \ --os-type=linux \ --os-variant=rhel6.3 Bug 808071 will not be fixed in RHEL6. Moving to RHEL7. Paolo, I have corrected example 6.1 with the RHEL6 guest configuration from Comment 6. Thanks for providing that. Could you please confirm - do we need to include a note on any of this from Comment 0 (below) in the guide? From what I understand, the virtio-scsi driver will be available in RHEL 6.4, but the virtio-scsi controller will *not* be in RHEL 6.4. Is that correct?

Thanks for providing that. No, that part of comment 0 was correct. In fact, there is no need to change the text for now; the guide is already correct. However, when adding the note it makes sense to make the two examples more similar to each other, hence the change. The correction in example 6 should have been to the text in the new note. All components of virtio-scsi are already in 6.3, and the controller is documented in the RHEL6 virtualization administration guide. The problem is that virt-install was not updated to support it, so we will only document the controller in the RHEL7 installation guide. I think we can keep this change on hold until we know whether virtio-scsi will still be TP on RHEL6.4 or not. Thanks for the info, Paolo. We'll keep the virtio-scsi and controller examples out of the 6.4 book and revisit for RHEL7. We still need to update the example to a RHEL6 guest. I've created https://bugzilla.redhat.com/show_bug.cgi?id=854437 for this issue. I have CCed you on that bug. |
