Just some food for thought, I did a simple analysis of the size of Xen Linux patches verses the VMI patches. To make things more fair, I removed everything from the XenoLinux port accept for the i386 xen subarch (so no drivers and no support for other architectures).
Your analysis is still taking all the patches to make dom0 functionality
work, which accounts for a lot of changes and is totally outside of the
scope of VMI.

We've been working with a bunch of RH/Novell folks to create a stripped
down domU-only Xen patch that would be a fairer comparison.

Here's a really imprecise view into that.  Keeping with Anthony's
metrics:

 88 files changed, 7637 insertions(+), 436 deletions(-)
Interesting.
That's near meaningless, as it's not something that would compile and
run, but gives you a scope of the size of the changes for domU only
(shadow mode), no Xen drivers, etc..
Okay, but that is on par with the amount of changes present in VMI. That's a really interesting data point.

Thanks,

Anthony Liguori
