Dear Nagu, Thanks for clarification. In my case, all these VMs works as payload. Have you tested how many these concurrent failures OpenSAF can support? I am using 4.4.0.
By the way, I am working in OP-NFV for HA proposal? Have you joined the same work-force, and is there any issue applying OpenSAF to these virtualized environment? Thanks.

Going detailed: 1. If Node 1 and Node 2 are controllers and Node 1 reboots, the scenario works fine. 2. If Node 1 and Node 2 are payloads (Of course, there is one controller in the cluster at Node X), then the scenario works fine. 3. If Node 1 is payload and Node 2 is controller and Node 1 reboots, then the scenario works fine. 4. If Node 1 is controller and Node 2 is payload and Node 1 reboots(and there is one another controller in the cluster), then the scenario works fine. 5. If Node 1 is controller and Node 2 is payload and Node 1 reboots(and there is no other controller in the cluster), then the scenario will not work as OpenSAF cluster requires one controller.
