I have one VM on my laptop and two dev boxes - all serving out sshd,
nfsd, and smbd - on which NM's running with only an ifcfg-lo file.

Furthermore, since the boxes can ping each other and there's one-way
ssh access, the presence/absence of an ifcfg-* file isn't issue.

I'd focus on troubleshooting sshd on box6.
