Ken,
   I've built LFS several times in different virtual environments.  For 
instance, BLFS shows how to build qemu-kvm.  When I was developing that, 
I loaded a Fedora iso and built LFS from there.  There were no 
differences that I recall except that the kernel drivers have to be 
specified for the virtual hardware.  The host, of course, was LFS.

If the appropriate virtual file systems are mounted (/sys, /dev, /proc, 
etc) there are no changes needed to build LFS.  From a theoretical 
standpoint where would the changes be?  The only code that accesses hw 
is in the kernel drivers.

LFS -> qemu-kvm -> Fedora -> /mnt/lfs -> new lfs

Substitute the first host, virtual system, and virtual host with your 
choice.  Any should work.

The same goes for

any host -> ssh linux target -> /mnt/lfs -> new lfs
