(I've put some debugging statement in the tap driver) I don't understand because I do see a successful close() from vmware (using ktrace). Writing a simple app that opens '/dev/vmnet1' and closes it again works fine. What would be the difference for this simple case and the vmware case? (I also made a linux binary of the same simple program and that one works too, just to be sure) Making a simple (and very possible wrong) conclusion is that the open call gets lost between userland and the driver. (vfs layer?) Any hints on where too look further would be very helpful.
