I've set up a failover group according to this https://www.virtualmin.com/documentation/cloudmin/vm/failover but the option to manually fail over seems to be missing from the web GUI? The manual states that "you can force a failover at System Operations -> Force Failover" but there is no such option either under the hosts or the VMs. I've tried both Authentic theme and the old Webmin theme to check if it's a theme issue.
I've set up the failover group with two host machines and a single VM to be manually failed over. The VM is running on a glusterfs brick mounted on both machines.
