<div dir="ltr">Hi<div><br></div><div>It seems that the problem is related to scheduling, note that once you assign a Datastore (images and system both are needed) to a cluster, OpenNebula will only allocate VMs to hosts in that cluster (so they are assumed to be configure with access to the datastores and networks in the cluster)</div>
<div><br></div><div>So could you double check that hosts, datastores and networks are in ifx_cluster? From the log they need to be in cluster 101</div><div><br></div><div>Cheers</div></div><div class="gmail_extra"><br><br>

Update. I switched from using iscsi to nfs. Same problem. Sunstone shows<br>
the mounted file system. Then when I try to instantiate a host, the<br>
Sunstone forgets all about the mounted system datastore and then I get the<br>
error.<br>
<br>
Apr 15 16:52:45 2014 : No system datastore meets SCHED_DS_REQUIREMENTS:<br>
CLUSTER_ID = 101 & !(PUBLIC_CLOUD = YES)<br>
<br>
Is there a problem with Sunstone that it can't deal with nfs or iscsi<br>
mounted file systems? Or has it something to do with mounting two<br>
filesystems at the same time?<br>
<br>
I've been googling until my fingers bleed and I'm unable to find any<br>
information about how to fix this problem?<br>
<br>
Sure could use some help with this problem, or at least a link to<br>
information.<br>
<br>
BTW, I'm running OpenNebula 4.4. It's running on a host and virtual<br>
machine running CentOS 6.5.<br>
