I think this is the right level myself. Advisory locks work okay but not all filesystems support them. It's particularly nasty when you have a clustered filesystem in the host. I think it would do more harm than good to have a feature like that was supposed to provide a safe-guard but then frequently didn't work.
^^^^^^^^^^^^^^^^^^^^^^Are you trying to say that any kind of significant portion of QEMU users have clustered file-systems?
I think that's unlikely, and it'd be nice if QEMU by default did a fcntl() on writeable image files to lock itself from multiple access, that'd benefit the vast majority of users.
Let the 0.x% of users who need to run with weird/esoteric fses cope.. regards, -- Paul Jakma address@hidden address@hidden Key ID: 64A2FF6A Fortune: Fashions have done more harm than revolutions. -- Victor Hugo
