[one-users] one running in vm

Wed Apr 16 07:56:38 PDT 2014

Hi

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)

So could you double check that hosts, datastores and networks are in
ifx_cluster? From the log they need to be in cluster 101

Cheers
