How to enable High Availability on a Citrix XenServer pool

HA can be enabled on a pool using either XenCenter or the command-line interface. In either case, you will
specify a set of priorities that determine which VMs should be given highest restart priority when a pool is
overcommitted.

Requirements

- Citrix recomend Minimum 3 XenServer Hosts (In this demo I'm using 2)

- Shared Storage*

- Resource Pool

- Static IP Addresses for all XenServers

- VM connected to pool-wide network**

- VMs not connected to any host DVD drive configuration

- All VM virtual disk on shared storage accessible pool-wide

-------------------------------------------------------------

* 4MB for heartbeat volume, 256 MB for metadata volumen

** Use bonded management interface

See you next time.
