- Unable to configure cluster with VMs running on different ESX hosts.
- Fencing is not happening properly when VMs are running on separate ESX
- Yes, it is possible to configure Red Hat cluster between VMs running on separate ESX. For that make sure all the usual multicast routing is in place as per a physical cluster, otherwise the Multicast traffic won't route between the 2 ESX nodes and thus the cluster will fall apart.
- When it is configured on a single ESX node, the vswitch inside ESX is smart enough to handle the Multicast traffic, allowing the cluster to work fine.
- For a successful fencing ensure fence agents are able to communicate with the VMware vCenter server that is managing the virtual machines.
