Changes

Secondly, the ''xend-relocation-hosts-allow'' value must be changed to define the hosts from which relocation requests will be accepted. This can be a list of hostnames or IP addresses including wildcards. An empty value may also be specified (somewhat insecurely) to accept connections from any host. The following example allows migration requests only from a host with the Ip address of 192.168.2.20:

(xend-relocation-hosts-allow '192.168.2.20')
