I have two physical servers (recent, Haswell based machines) on which I have installed XenServer 6.5 . Both servers have two NICs. These servers are hosted at the Hetzner datacenter.
I have connected a LAN crossover cable between the two servers on one of the NICs.
The other NIC on both servers are facing the Internet directly, with a public IP assigned. I connect to the servers (SSH or XenCenter) using this public IP.
Both servers have only local storage. No shared storage.
From both servers, I am able to ping the public IP and the private IP of the other server. No problems there. The xenbr0 has the public IP and the xenbr1 has the private IP on both servers.
I want to put both servers in the same pool and be able to migrate the VMs between them (Storage XenMotion). But when I try to drag a VM from one server to another, the subsequent dialog box does not allow me to select that server. The reason it gives: No route to host.
I have installed the separate NIC precisely for the purpose of having a dedicated internal network for VM migrations.
What do I need to do to make it work?
Thanks.

Storage XenMotion makes use of the Management Interface (in your case it should be the xenbr0 - bridge or you call it virtual switch), if the 2 management interfaces cannot communicate with each other, Storage XenMotion will fail.
You need to create a separate Storage Network (using IP in your private network 192.168.1.0/24, and configure an IP address for the 2nd NIC on each host) 1st, and when doing the Storage XenMotion, when asked which Storage Network to use (step 4 - live migration network), choose the storage network and it should work.
