Hello,
I have some server in OVH, i need to migrate some VM to one proxmox server to other proxmox server, alwaise in Ovh but in a differente datacenter? Is possible to activate cluster? And how?
 
Hi, we did that. We configured vrack on second proxomox nic, configured corosync to use this second interface changing /etc/hosts to map proxmox hostnames to vrack ips. As cross datacenter networking has latency we decided to use udp instead of multicast for cluster communication.

So i need to buy vrack on ovh?
 
I think is better to have a dual nic server on OVH, one public and one inside vrack. We configured a three node with 10Gb/s nic on vrack and works perfectly with sheepdog too.
