Actually in FreeBSD, it is possible to run an older userland on a newer
kernel,
and a lot of effort is spent in preserving this type of backwards
compatibility.
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-gsoc-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.
