[one-users] one running in vm

[Neil Schneider]

Update. I switched from using iscsi to nfs. Same problem. Sunstone shows
the mounted file system. Then when I try to instantiate a host, the
Sunstone forgets all about the mounted system datastore and then I get the
error.

 Apr 15 16:52:45 2014 : No system datastore meets SCHED_DS_REQUIREMENTS:
CLUSTER_ID = 101 & !(PUBLIC_CLOUD = YES)

Is there a problem with Sunstone that it can't deal with nfs or iscsi
mounted file systems? Or has it something to do with mounting two
filesystems at the same time?

I've been googling until my fingers bleed and I'm unable to find any
information about how to fix this problem?

Sure could use  some help with this problem, or at least a link to
information.

BTW, I'm running OpenNebula 4.4. It's running on a host and virtual
machine running CentOS 6.5.
