Yea, the configdrive is a non-issue for us since we don’t use those. The multi-drive issue is the only one really affecting us. While removing the second drive and reattaching it after boot is probably a good solution, I think it’s likely the issue will come back after a hard reboot or migration

There is a small patch in the bug which resolves the config drive ordering. Without that patch I don't know of any workaround. The config drive will always end up first in the boot order and the instance will always fail to boot in that situation. For the multi-volume instances where the boot volu

Hi, Lately, we’ve been converting our VMs block devices (cinder block devices) to use the virtio-scsi driver instead of virtio-blk by modifying the database. This works great, however, we’ve run into an issue with an instance that has more than one drive. Essentially, the root device has addres
