This is the purpose for which we (ab)use jails for too.  Works great,  
less filling.

Check out ezjail in the ports; it makes very lightweight jails by  
using nullfs to share the full install tree across multiple jails.   
This may not be what you want, but it is what I wanted.

What you don't get is a private kernel per jail, and some services  
are not really virtualized like network, and SYSV IPC.  And you can  
only assign one IP per jail.

For what I need, Xen is overkill.
