you will notice that bosh will try to respawn the vms/jobs he created because of the health monitor so what we normally do is disable the bosh health monitor until the the nodes are done greetz Ramonskie -----Original Message-----

As long as VM remains powered on and accessible you should not have a problem. In practice you may run into certain OpenStack limitations which may prevent moving VMs around. I vaguely remember presence of a config drive (CPI is configured to bootstrap VMs via config drive) may limit VM relocation.

We're running open source Cloud Foundry on OpenStack, and the admin was wondering if the CPI could handle a particular VM (or a set of vms) being transferred from one physical node to another for something like maintenance on the original node. My first thought is that it shouldn't affect anything in the CPI, since OpenStack is handling the VM provisioning and locating, but I was curious if anyone had practical experience with this. Thanks!
