Hi, Cool ... I can live with that. The purpose of teleporting in my solution thus far is primarily to move VMs to another host so the original host can be taken offline usually for modification/upgrade/repair. Once the original host is back online, the VMs will be teleported 'back'.
At some point in the future, the automated teleporting operation will be used to load balance a host that might get overwhelmed. For now, I'll simply use VBoxManage to clear the flag ... and hope that a near future release addresses it before I need to handle supporting dynamic teleporting back and forth. Thanks !!!

The problem has to do with saving the VM settings at that point in time. It will be addressed in one of the next releases, I hope. -- Kind regards / Mit freundlichen Gruessen / Vennlig hilsen, bird -- ORACLE Deutschland B.V. & Co.
