I have FreeBSD 9.0 installed as a VirtualBox guest, and I plan on

Another option to look at is using FreeBSD's Jails. Handbook chapter 16
Basically you can setup multiple jails on the machine that use the
kernel of the base system (so it's not an entire emulated machine) but
each jail has it's own environment, apps etc.
I read up on jails and I am impressed, I had a vague idea about them but
they are apparently a lot more powerful than I thought. This will get
some use from me in the future when I'm setting up real servers.
However, for what I'm currently doing, I want to stick with a bunch of
VirtualBox VMs so I can simulate database failover by killing the VM in
rude way, dynamically throw another "machine" into the mix, etc.
Thanks!
