[Impact] By default, currently Power guests are defined with bus=?scsi? disk type. Virtio disks will perform much better in KVM environments than the scsi (papr) model so the default should be changed to improve out-of- the-box guest performance. [Test Case] Create a guest using virt-install or virt-manager, check the default disk type with ?virsh dumpxml <guest>?. Ex. virt-install command: virt-install --force --name test --ram 4096 --vcpus 4 --location <location path> --noautoconsole --wait=-1 --noreboot --nographic --disk path=/var/lib/libvirt/images/test.raw,size=10 [Regression Potential] Virtio tends to get more test cycles in general, so changing the default may actually reduce the risk of regressions with the papr scsi type. [Other Info] All guests that can run on Power support the virtio-blk disk type. -- Also removing the network portion from the bug title, we will need to follow up on that later once changes make their way upstream. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1597610 Title: virt-install default to virtio type - disk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virt-manager/+bug/1597610/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
