this is expected, as there is no 'guest' networking
(without ngnet) all networking is done on the host
so nmap will always see 'the host' ...

this might be related to the host's sshd binding to
all available ips, leaving none for the guest to bind
to ...
solution: restrict the host sshd to a subset of the
network addresses ... and restart the vserver's sshd
