[pve-devel] working on livemigration + storage migration

Yes, I have a 2 fibers between the datacenters, (Layer 2), so I don't move ip ;)

I'll use same proxmox cluster.

It's virtually 1 big virtual datacenter, using layer 2 network, I have around 1ms latency, so it shouldn't be a problem.

(I would like in the future to do replicate storage (rbd,sheepdog,...) between datacenters, to have active-active cluster setup :)

A great feature - nice to hear. 

A bit off topic - how do you move the IPs? Do you have a custom Dark 
Fiber between the Data Center which you use as an internal network? 

How do you integrate the "new" cluster? Is it a new one or do you attach 
the nodes to the current pve-cluster? Does this work for corosync 
especially for latencies?
