Another way to test it might be something like this: nbdkit -v -o random 1G --run './src/nbdcpy --source \$port --destination \$port' (You could use other plugins instead of random, such as data, sparse-random, memory, etc.) Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-top is 'top' for virtual machines.
