SUMMARY
A single VM from a newly added clustered ESX host may fail to display in the appliance UI.
ISSUE
When a clustered ESX host is added to the appliance, a single VM on that host may fail to display in the appliance UI. Moving the VM to a different host in the cluster will cause a different VM on the original host to not display.
RESOLUTION
To resolve this issue, upgrade your appliance to version 10.1.
