First, I am not sure what you mean by 'virtual machine'. That may throw
a monkey wrench in things if it means that literally.
But, the main thing I would add is before you do the mount /usr
you probably want to cause root to be remounted read/write so you
can edit rc.conf. To do this, do
mount -u / (or even just mount -a I think will cause it
to happen nowdays)
Otherwise root will be mount read only and you won't be able to
change rc.conf
