Hi all
I'm playing with the boot from volume options in Havana and have run into problems:
(Openstack Havana, Ceph Dumpling (0.67.4), rbd for glance, cinder and experimental ephemeral disk support)
The following things do work:
- glance images are in rbd
- cinder volumes are in rbd
- creating a VM from an image works
- creating a VM from a snapshot works
However, the booting from volume fails:
Steps to reproduce:
Boot from image
Create snapshot from running instance
Create volume from this snapshot
Start a new instance with "boot from volume" and the volume just created:
The boot process hangs after around 3 seconds, and the console.log of the instance shows this:

The console is stuck, I can't get to the rescue shell
I can "rbd map" the volume and mount it from a physical host - the filesystem etc all is in good order.
Any ideas?
cheers
