>Description:
in file /sys/rump/net/lib/libvirtif/runcomp_user.c
 in rumpcomp_virtif_create(int devnum, struct virtif_user **viup)
need to change " int rv"  => to "int rv = 0" in order to init rv at start

>How-To-Repeat:
run from examples folder => webbrowser.c (the if create function should fail 
and return 22) (EINV)
>Fix:
Initilize rv to 0
