XEN-HA Cluster Demonstration on YouTube

Andreas Ender from SECURE_iT sent me this excellent demonstration video…

Georg Dörn from www.its-doern.at has built a XEN cluster solution.

This Video shows you an RDP session while live migration of a Windows 2008 R2 terminal server running as a virtual machine on a XEN-HA cluster.

Within the RDP session a video is playing while live migrating the terminal server vm from one XEN-HA cluster node to the other node and back again without any downtime.

Only one ping is lost while migrating. You will see a very short stop playing the video at 1:06 and 2:12.

The XEN-HA Cluster is based on two identical Debian 5.0 XEN Hosts with drbd (raid 1 with sata disks and sync with 2 x gbit nic) and heartbeat.
The whole system runs with open source software! This XEN-HA cluster is not any experimental system. It works as a production system at many customers from us.
