From: Rusty Russell <rusty@rustcorp.com.au> lguest is a simple hypervisor for Linux on Linux. Unlike kvm it doesn't need VT/SVM hardware. Unlike Xen it's simply "modprobe and go". Unlike both, it's 5000 lines and self-contained. Performance is ok, but not great (-30% on kernel compile). But given its hackability, I expect this to improve, along with the

Andrew did a great job of merging in the PDA->percpu changes and lguest code for 2.6.21-mm1, but the load_gdt is now unnecessary.

Andrew Morton commented out some stuff to make lguest compile. This should actually make it work (in the latest -mm).

As promised to Andrew, and with much thanks to Andi Kleen for feedback, this is the new series of lguest patches. Main change is the move to drivers/lguest (for future non-i386 expansion), but lots of cleanups driven by Andi's feedback and the documentation effort (which made me examine every line of code). It's not perfect, but it's definitely useful. Cheers, Rusty. List of

Here's a first attempt at splitting up paravirt_ops into more specific chunks. Its pretty clunky and chunky; mostly just a lot of replacement. The grouping of ops is very first cut; I'm open to suggestions about what groups should exist and what ops they each should contain. The only slightly subtle part is that I've kept the structures wrapped in a paravirt_ops structure,

The netfilter code had very good documentation: the Netfilter Hacking HOWTO. Noone ever read it. So this time I'm trying something different, using a bit of Knuthiness.
