[Qemu-devel] guestfwd option doesn't allow supplementary , server, nowai

The option formerly known as -net channel was changed to:

  -net user,guestfwd=[tcp]:server:port-dev

which in general would be an improvement.  libguestfs currently uses:

  -net channel,6666:unix:/some/path,server,nowait

which works (probably by accident, because the code happens not to use
get_param_value).  However in the new syntax that would be:

  -net user,guestfwd=tcp:,server,nowait

This gives errors like:

  qemu: invalid parameter 'server,nowait' in 

It seems like the code tries to do the right thing for the hostfwd and
guestfwd parameters.  There is a while loop which seems to check for
these parameters explicitly, but it doesn't work -- I'm not sure why.

libguestfs is continuing to use the old, working -net channel form of
this parameter, so please don't remove it.
