After a fresh install of v-magine I tried to launch an instance of the ciro image but it failed with the common error message:

No valid host was found. There are not enough hosts available.

Looking at the nova-compute.log shows that there were some issues with attaching the volume to the instance:

Unable to attach volume to instance instance-00000001

It works when I create an instance without a volume which suggests there is something wrong with volume creation. I installed v-magine onto a Cluster Shared Volume that communicates between nodes via Server Message Block (SMB) 3 and 10GbE Remote-Direct Memory Access (RDMA) networking. I don't have a SAN (FC or iSCSI).
