I tried running FreeBSD using Parallels a while back and didn't get very far. JC is using Jails. An easy way to tell is if you run 'ifconfig' and don't see the loopback address (127.0.0.1). This is a restriction of the jails system. Another hint is if you run 'mount' and see that the device mounted as / doesn't exist in /dev. The main disadvantage of jails is that you cannot mess with the kernel, but otherwise I think it's actually a better solution, in my opinion. Less resources are wasted with jails than with a full VM. A Xen or VMWare server will behave exactly the same as a physical machine. - Max
