[Swan-dev] test domain interface changes

[Andrew Cagney]

I'd like to make the following changes to the domains:

- make eth0 swandefault across all domains
  this makes getting to the real domain and host much exier (OpenBSD
is already using swandefault when NFS mounting /testing)

- give all domains access to all internal networks, and with the same ifname
  this way, if east/west use eth1 then you know they are on the same
physical network
