Bug Description

Binary package hint: virtualbox

Virtualbox will not use the VT-x processor feature because it believes the kernel version to be too old. This is because it does not properly parse the new 3.x kernel version strings.

Function is called "suplibOsQueryVTxSupported" on line 257 of
src/VBox/HostDrivers/Support/linux/SUPLib-linux.cpp

According to a comment upstream, it is fixed in SVN and will be included in the next maintenance release (4.0.10?).

Hopefully this should be out in time to make it into Oneiric without any extra work.
