How to Resolve FreeNAS No configured interfaces were found

Lately, I tried to build NAS on a Virtual Machine, I chose FreeNAS 9.3 as the platform, but I got the error:

No configured interfaces were found. Try to do it manually

on the entry menu after installation. And no way to access its WebGUI.

Since VMware recommended 256MB for BSD VMs as a starting point during configuration time, so I think it maybe that the memory size was too small to allocate the memory for the network interface or nginx.

So I increased the memory size from 256MB to 1024MB (1GB), the problem solved.
