Good day, I have run into an interesting problem with VirtualBox on Linux machines. I am running Ubuntu Hardy (x64) version and have multiple machines created. They are all running just fine, except one. When I shut down the virtual machine, (either by "Start-Shutdown" or by telling VBox to power it off, the system shuts down, and shows completly powered off in the log, but the Main VirtualBox window shows that it si "Powered Off", but that the session is open. In this state I can no longer power it on, or make configuration settings changes. I actually have to reboot the machine to clear this error. It is only occuring for this one machine. All other machines seem to work just fine. Does anyone have an idea of what this is, or how to clear it out. I have looked at the xml config files and don't see how this status is being tracked. The virtual machine is most definately powered off.

Thanks for the help.
