You have now completed the High Availability lab. In this advanced lab, you have successfully enabled power management for your hosts and configured high availability for your virtual machines, and tested their effects in five typical enterprise use cases.

In conclusion, when a host malfunctions, but can still communicate with the Manager, it will try to migrate high priority virtual machines to other hosts in the cluster. If the host cannot connect to the Manager, it will trigger a fencing operation and reboot. In this case, highly available virtual machines will restart in a different host in the same cluster; while non-highly available virtual machines will remain shut down unless manually restarted even when host has finished reboot and is back up.

The next lab in the Advanced Track for Multiple Hosts concerns data centers . It will teach you how to create a new data center with Red Hat Enterprise Linux hosts.
