There are some things about the Xen installation process that are not
clear to me.  I have successfully run "make world" on the xen-source and
notice it has built a bunch of kernels for me.  However, in the Xen
User's Manual almost nothing is said about the kernel building process
nor what the disctinction is between these various kernels it builds.

My question is: Why should the user not just patch the kernel with
whatever required patches there are and then compile the kernel himself?
The make script seems to be nice but unfortunately I have no idea what
it is actually doing.  For example, are there specific options in the
Linux kernel which need to be disabled or enabled for the Xen kernels?
Why not just instruct the user to patch the kernel with the appropriate
patches and to dis(en)able whatever options are necessary?

I would be much happier if the whole process was a little less automated
yet more clear to the user (who if they are to the point of installing
something like Xen, presumably also already have experience building a
custom kernel).

Anyhow, I already have the source for the customized kernel my machine
is running in /usr/src/linux.  I noticed that the kernels that Xen built
did not include some required options for my machine (such as XFS
filesystem support) so now I am totally confused.
