I'm new to seL4 (and L4 generally).  I'd like to initially run my application 
functionality in Linux on top of seL4 (x86) and then over time migrate pieces 
of its functionality to run directly on seL4 to achieve finer-grained 
confinement.

I'm having trouble finding any instructions on how to run a Linux environment 
on top of seL4.  Either paravirtualized or hardware virtualized would be ok.  
So far I found pointers to L4Linux but it appears to need L4Re.  Can anyone 
point me in the right direction?

The instructions are sparse, we should add at least a README.

We no longer support para-virtualized Linux (as in L4Linux), too much work and 
no longer justified with hardware support widely available. We support 
hardware-supported virtualisation on x86 and soon on ARM.

On x86, the kernel runs in Ring-0 root mode, and virtualization events are 
reflected to a virtual-machine monitor (VMM) running in Ring-3 root mode. On 
http://sel4.systems/Download/ there is a rerference to a CAmkES-based VMM at 
https://github.com/seL4/camkes-vm-manifest.
