Sure.  Although it is a bit more complex that just a simple string.
With qxl guest drivers moving to kms as we'll have two driver components
then.

Depends on the problem.  $feature not working and qxl seeing the driver
not using the new ops for $feature is helpful.

Indeed, being able to match the driver version against a database of
known-buggy versions is nice too.  That will only work for new drivers
which actually report the version though (assuming we go that route).

But there we are again at the level where going through the guest agent
might be a better way.  "rpm -q kernel xorg-x11-drv-qxl" gives you what
you need ...

cheers,
