Multinode testing is something we have all wanted for a long time. We have had it for a while now but its applied inconsistently. We should figure out where this fits in our testing setup. Do we replace single node default tests with multinode tests? Do we use this only for testing special things like DVR and live migration?
The test env can be complicated and adding more nodes raises the bar on reliability requirements. There is a lot to consider here and likely need broad input to determine what the future is with multinode testing.
