# Failover

HVM supports automatic failover of running workloads in the event of the loss of a host. Administrators can control the failover behavior through the “Manage Placement” action on any running VM. From the VM detail page, click ACTIONS and select “Manage Placement”. Any VM with a placement strategy of “Auto” or “Failover” will be eligible for an automatic move in the event its host is lost. When the loss of a host does occur, the workload will be up and running from a different cluster host within just a short time if it’s configured to be moved during an automatic failover event. Any VMs pinned to a lost host will not be moved and will not be accessible if the host is lost. When the host is restored, those VMs will be in a stopped state and may be restarted if needed.

This three-node cluster has three VMs running on the first host:

Each of these VMs is configured for a different failover strategy. When the host is lost, we should expect to see the first two VMs moved to an available host (since they have the “Auto” and “Failover” placement strategies, respectively). We should not see the third VM moved.

After loss of the host these three VMs were running on, we can see the lost host still has one associated VM in a stopped state. The other two VMs are running on a second host which is still available.

When the lost host returns, the moved VMs will come back to their original host. The third VM is associated with this host as well and is in a stopped state until it is manually restarted.
