In a sense this is just like live migration if I understand. If you migrate a domain to a new machine and assume the IP address there (with an unsolicited ARP broadcast), a TCP connection will continue transparently -- as long as the routing is worked out (i.e., intra-cluster migration will work like this without a special framework). > That is suppose I have two instances of XenoLinux > running some services.

There were a number of interesting conversations about this type of fallover recently, cf. http://thread.gmane.org/gmane.comp.emulators.xen.devel/4729 http://thread.gmane.org/gmane.comp.emulators.xen.devel/5329 http://thread.gmane.org/gmane.comp.emulators.xen.devel/4893 > For the client everything happens transparently > and no interruption of the service is observed.
