What is supposed to happen is that qemu-nbd is started (3 times) on
the virt-p2v machine.  Then 3 x ssh connections are made which reverse
proxy the nbd connection from virt-v2v back to virt-p2v, the
equivalent of:

  ssh -R 33363:localhost:<hostport> virt-v2v-server

Somehow that's not happening.

I'm not sure what.  Is this reproducible?  Do you have an unusual
firewall configuration on the virt-v2v conversion server?

Rich.
