Do not meddle in the internals of kernels, for they are subtle and quick to
panic.

could you (or anybody) elaborate on that? the mmu-related threads show
lots of progress, but it's way (way) out of my league.
AFAICT, it's about the infrastructure to l

Thanks for your detailed explanation :). That's quite helpful for me
to understand KVM internals.

Hi Avi,
I have a question about KVM architecture after reading your paper.
It reads:
..
At the kernel level, the kernel causes the hardware
to enter guest mode. If the processor exits guest
mode due to an event such as an externa

Hello,
I'm interested in learning the technical details of KVM, possibly up to
date with latest versions (KVM changes so fast!). I'm not really geared
to development (yet), rather I would like to study its architecture from
a security point of view.
I've searched anywhere and all I could find
