I'm not sure about FreeBSD 4.x, but with the more recent versions, the
solutions I've seen were using jails, Xen, or VMWare. 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.
