I had a little trouble setting up VMware to share the host's (Ubuntu) nic interface eth0 (with static ip) with the guest ncp2.
Follow the instrucions here to setup a VMware install: http://www.nexenta.org/os/Getting_Started
When you need to pass network settings, for a static IP configuration on the host, follow the below steps.
Lets say the guest is setup as
IP:192.168.1.2, with netmask 255.255.255.0 and router 192.168.1.1
Then host needs to be
IP: 192.168.1.3 (or 4 or 5..), with netmask 255.255.255.0 and router 192.168.1.1
