1. go into the VMM database to the table tbl_WLC_VObject, and change the ObjectState field of the problem VM, which probably has the value 104, to value 1
** At this point, i went direct to the table and edit the value manually. Of course I did this because this I a Lab environment.
update dbo.tbl_WLC_VObject
set ObjectState = 1
where Name = '<VM name>'
2. in VMM admin console, you're VM will now have the status missing, now just delete the VM and it's gone.
