Because of the non-root networking technology we use (SLIRP), 'ping' doesn't work and there are other shortcomings. See: http://libguestfs.org/virt-rescue.1.html#network If you use the libvirt backend, it is able to set up a real network without needing root (but using a setuid program called 'qemu-bridge-helper' supplied by qemu), but we don't have that for the direct backend yet. http://libguestfs.org/guestfs.3.html#backend Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-builder quickly builds VMs from scratch http://libguestfs.org/virt-builder.1.html _______________________________________________ Libguestfs mailing list [email protected] https://www.redhat.com/mailman/listinfo/libguestfs
