If I am using an HA cluster in vSphere 5.5 and I want to use Openstack in the future to provide mutlitenancy, where multiple tenants will share the same cluster, how does that impact my cluster design? Can I still use the VMware HA cluster with OpenStack mutlitenancy? I know VCD can work with existing HA clusters and allow multiple virtual datacenters owned by diferent clients to use the same HA cluster and maintain isolation. Can openstack do this or do I have to break up my HA cluster and let Openstack manage the individual ESXI hosts?
THanks!
