So a 9.1 userland with a 10 kernel will work. However, running a newer userland on an older kernel is not guaranteed to work. So running a 10 userland with a 9.1 kernel will most likely not work. However, since you guys are doing very cutting edge stuff with 10-CURRENT, it is better that you do not waste time with 9.1. I recommend you start with a 10.0 CURRENT snapshot ISO and go from there. I am going through a similar setup exercise with a Google Summer of Code student where he needs to have a latest CURRENT system running in a VM. I wrote this blog post: http://blogs.freebsdish.org/rodrigc/2013/05/24/setting-up-a-vm-for-doing-gs= oc-work/ for the steps how to do it. You can follow those steps to get bootstrapped with a working environment if it helps you out. Good luck. --=20 Craig
