Yes I have portmap working well in two different virtual hosts and even
portmap with that chbind --ip 127.0.0.1 in the main server too at the
same time.

chbind --ip <master-ip> starts portmap well, but NFS-server or any other
RPC-programs can't connect it.

I have tried also put "<master-ip> localhost" in main server's /etc/hosts.
but that doesn't help either.
I think vserver system handles localhost and 127.0.0.1 different in the
main server and virtual hosts....
