- Live Migrating OpenStack VMs between physical nodes
Re: Live Migrating OpenStack VMs between physical nodes
OpenStack CPI does not care / is not aware on which node VMs are running.

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

I've had a question from my client's IT department that I thought I would
run by you before actually just trying it. 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.
