Comment 20 for bug 1821696

So here is:

1. information about volume and image. I have experimented in our lab with setting SCSI-properties on the Image. I belive this is the problem with the Hard Reboot. Horizon reports boot image attached to /dev/vda but in virtual instance:

[cloud-user@malo-test ~]$ sudo fdisk -l

Disk /dev/sda: 21.5 GB, 21474836480 bytes, 41943040 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x000b288e

   Device Boot Start End Blocks Id System
/dev/sda1 * 2048 41943006 20970479+ 83 Linux

Disk /dev/sdb: 107.4 GB, 107374182400 bytes, 209715200 sectors

1. virsh domblklist before hard reboot

1. nova compute logs from when instance was booted

1. virsh dombklist after hard reboot
