See the section called “Changing IP address configuration in resource pools” for details on changing host IP addresses in resource pools.
Changing IP address configuration in resource pools
XenServer hosts in resource pools have a single management IP address used for management and communication to and from other hosts in the pool. The steps required to change the IP address of a host's management interface are different for master and other hosts.
Note:
Caution should be used when changing the IP address of a server, and other networking parameters.
