Supported fence methods: See applicable support policies for individual fence methods that may apply to VMware environments. To reference those that are most commonly considered in such environments:

Mixed baremetal and RHV VM clusters: Red Hat does not support clusters consisting of a mix of baremetal and virtual machine members.

RHV Highly Available virtual machines: Red Hat does not support the use of Highly Available RHV VMs as RHEL HA cluster members. The RHEL HA product has not been formally tested in conjunction with the RHV Highly Available VM setting. If you encounter a cluster issue that may be related to the RHV Highly Available setting, Red Hat may require that you reproduce the issue with this setting disabled.

If you believe that you need the RHV Highly Available VM setting, please open a support case so that we can better gauge demand.
