VMM Architecture documentation

I am looking for a low level description of the VMM architecture, if one
exists. Specifically which modules are required for 32 bit guests and which
are needed for 64 bit guests. Does this exist or do I have to sift through
the source code to find the differences?

We are kind of working through to make that easier to read.

But I am not actually sure what you mean by 'modules'?

I am looking to get a more modular view of the Xen architecture.  What Xen
VMM components are required to support a 32 bit guest, what components are
required to support 64 bit guest. Are there components that both the 32 bit
and the 64 bit guests share? How does HVM come into this (i.e. what code
supports the usage of HVM and what code is no longer needed if HVM is used)?

Is there a document out there that depicts this, or is it something you get
by going through the source code?

Source code.
