Cluster node resources usage

[Leo David]

Hello,
Maybe it is a dumb question, but I can't find an answer.
In a scenario with a 24 cores and 48GB ram installed on a particular node, we create 3 vms with 24 cores and 48GB ram each.
1. What will be happening ( on pmx node & each vm ) when / if these ram and cpu resources will be full used on all 3 vms ?
2. Is there a way or a policy that can be implemented to automatically live migrate vms to another low used pmx node if some threaholds are reached on vms or pmx node ?
Have a nice day !

Leo

Hello everyone. Any thought on this ?

1. everything will be dead slow, potentially causing system instability. overcommiting your resources is not a good idea, overcommiting them threefold even less so..
2. no (although you can add such functionality tailored to your needs, all the status and management calls are exposed over a REST API after all!)
