Re: "improves AI capabilities"?
The live migration is just as likely to be about relocating away from hosts that are going down for some reason.
At least that's a use case I've had alongside the load balancing triggers. Done properly it's really handy.
Migrating instances between hosts transparently should be a thing as often as possible as part of the reason for throwing things into a cloud should be that you don't really worry too much about the fine detail of where it's sitting, just that your resource demand is being satisfied. If you're tied too hard into needing to stay on a specific box for the duration you're negating a big reason for it being in a cloud instead of just a box.
Really it has sod all to do with AI beyond a chance to throw in the hot topic. It's really just better GPU support.
