OK, glad you got it to work.  What I see right away is that if you do not
specify the options:
   (1)  diskdev is the default image used.  If you have multiple VM's
running, it
         probably is not safe to use the same disk image across multiple
VM's, so you
         might want to have different disk images, and specify the -d flag.

That's a very good question.  So basically what I do is, first I look at:

to understand the layout of the different branches in FreeBSD.
Then I go to:

to look at the commits.  The commits targeted for the 10.1 release are
going into the  /base/releng/10.1
branch.  If you are familiar with Subversion, you can also checkout the
code from subversion and do
"svn log" to look the commits, as an alternative to the web interface.
