[vbox-dev] Major problem with latest from SVN

[Perry Halbert]

Latest from SVN r40927 completely ruins the Virtual Guest.  It comes 
back with the following.


Failed to open a session for the virtual machine Ubuntu-10.04.

The device instance structure version has changed.

If you have upgraded VirtualBox recently, please make sure you have 
terminated all VMs and upgraded any extension packs. If this error 
persists, try re-installing VirtualBox. (VERR_PDM_DEVINS_VERSION_MISMATCH).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: Console
Interface: IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb}

At this point you say ok and the VDI file becomes corrupt and Inaccessible.
There is no recovery from this that I can find as even trying to 
reattach it comes back with the Parent file does not exist in VirtualBox.xml

Reverting back to r40867 does not fix the corrupt files but does work on 
ones you have not tried to start.
