Updating virtualisation docs

[Charlie Clark]

Hi,

first of all great that there is such a section. I hit a wall a while back  
with FreeBSD 7.x on Parallels 4 on MacOS X. I couldn't get it to upgrade  
successfully to 8. Well, the upgrade went ahead but the network stack  
wouldn't work.

I recently tried a separate 8.1 install and after a number of tries came  
up with the following settings:

1) FreeBSD 8.x needs bridged networking, ie. a dedicated device. It can be  
installed on shared networking using the boot-only image but will  
subsequently fail to load a network device.

2) If installing on a shared network then when selecting an FTP server  
passive mode must be used.

3) A single slice for "/" seems to make sense on VMs like Parallels which  
can dynamically resize. I've been so often bitten by "/" filling up when  
installing ports, etc. that this option could, in my view, do with some  
greater publicity.

If desirable I can supply screenshots of my install.
