I don't know exactly where Xen for FreeBSD is at at the moment (keep meaning to go check), but I am pretty sure it can run as a guest OS. So you could have linux be the host and a bunch of FreeBSD guests... As for Jails, I have a box that has 2 jails on it that with very few exceptions look and feel like a full blown OS. I ssh to them. I run postfix, mysql, apache, rails, etc... all okay. The only isuses I run into are when trying to ping/traceroute/netstat/top.. Search around for 'ezjail'. It's a set of scripts meant to help you run a lot of jails while using very little space by sharing a lot of the files (ie, everything in /usr/(bin|lib|include)....) -philip
