Can you change that to VIR_DEBUG("send %d bytes", (int)bytes), and likewise for all other places using fprintf() for debug output. NB VIR_DEBUG doesn't need a trailing \n, it adds one for you. If you want to view the debug messages from libvirtd then just run it using LIBVIRT_LOG_FILTERS=1:macvtap LIBVIRT_LOG_OUTPUTS=1:stderr /usr/sbin/libvirtd and it'll print all VIR_DEBUG() lines in macvtap.c Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://deltacloud.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
