I know if I just take the vnet and the datastore out of the cluster, and have no clusters at all, then everything will work.. I was hoping to have a cluster structure of (host,vnet) pairings that could all share a common data store. However from the documentation, it looks like if your template requests any resource that is part of a cluster (vnet or image from datastore) then the scheduler will constrain you to resources that are part of that same cluster.
Is that correct? Steve Timm ________________________________________ From: Ruben S.

When a datastore or network is not assigned to any cluster (cluster default) OpenNebula assumes it can be used with any host (no matter in which cluster is set). BTW, although you do not needed for your use case, 4.12 will come with extended VDC support to create complex provision scenarios. Basically you can define generic "resource providers" that aggregate any resource (cluster, host, network, datastores) more here http://opennebula.org/4-12-features-virtual-data-center-redesign/ Cheers On Fri, Feb 13, 2015 at 6:37 PM, Steven Timm <t...@fnal.gov> wrote: > > I have had my one4.8 host up for a while with a single cluster > that has 150 hosts, one vnet, and a system and image datastore. > > I am now adding hosts from a different vnet. > want to make second host + vnet cluster but still use > the same system and image data stores. > > What's the right way to do that.. just remove the datastores > from the first cluster... they can't be in more than one > cluster at a time, can they? > > > Thanks for any suggestions. > > Steve Timm > > > ------------------------------------------------------------------ > Steven C.
