The throw an error.

-drive name=foo is also useless without a file= option.

Yes, the server and nowait options are unfortunate.  We should probably 
introduce mode=client|server and wait=on|off.   Best thing to do is 
completely swizzle the char device syntax.  Something like:

-char name=foo,type=unix,unix-path=/some/path,mode=server,wait=off

Then allow a char:<name> url to be used anywhere that takes traditional 
char device urls.

-net user,guestfwd=tcp:10.0.2.4:6666-char:foo
