Dear OpenStack-users,<br>
<br>
I just installed my first multi-node OS-setup with Ceph as my storage backend.<br>
After configuring cinder, nova and glance as described in the Ceph-HowTo (<a href="http://docs.ceph.com/docs/master/rbd/rbd-openstack/" rel="noreferrer" target="_blank">http://docs.ceph.com/docs/master/rbd/rbd-openstack/</a>), there remains one blocker for me:<br>
<br>
When creating a new instance based on a bootable glance image (same ceph cluster), it fails with:<br>

Dashboard:<br>
> Block Device Mapping is Invalid.<br>

<br>
Glance seems to work well. I was able to upload images.<br>
Creating non-bootable disks seem to work, as soon as I try to make one bootable, it fails.<br>
<br>
This seems to be related to the known threads I found online but the mentioned fix was merged long before Liberty so I am finaly stuck at this point.<br>
<br>
How can I fix this problem?<br>
<br>
Thanks.<br>
<br>
Kind regards<br>
Kevin<br>
