You can configure VMware HA to designate a specific host as the failover host.

With the Specify a Failover Host admission control policy, when a host fails, VMware HA attempts to restart its virtual machines on a specified failover host. If this is not possible, for example the failover host itself has failed or it has insufficient resources, then VMware HA attempts to restart those virtual machines on other hosts in the cluster.

To ensure that spare capacity is available on the failover host, you are prevented from powering on virtual machines or using vMotion to migrate virtual machines to the failover host. Also, DRS does not use the failover host for load balancing.

The Current Failover Host appears in the VMware HA section of the cluster's Summary tab in the vSphere Client. The status icon next to the host can be green, yellow, or red.

Green. The host is connected, not in maintenance mode, and has no VMware HA errors. No powered-on virtual machines reside on the host.

Yellow. The host is connected, not in maintenance mode, and has no VMware HA errors. However, powered-on virtual machines reside on the host.

Red. The host is disconnected, in maintenance mode, or has VMware HA errors.
