- VBOX: For hosts who do not have processors with VM extensions try 

and disable the use of them at VM creation time.  Certain actions
        within VirtualBox will force enabling them at runtime and cause
        an error (like SMP support) but it should reduce confusion between
        volunteers and projects when a VM configuration change now causes
        a class of machine that used to work suddenly stop working.
    - VBOX: Add some more helpful text notes for error conditions that
        the volunteer might be able to address.  For instance other
        hypervisors locking the VM CPU features for exclusive use.
    - VBOX: If we have to dump out the VM execution log on Windows, remove
        excess carriage returns from the spew.
