1) Example code: old libc headers don't have SIOCBRADDIF, and old zlibs don't have gzdirect() -- it's a sanity check anyway. 2) Some people don't build in their source directories, so .config isn't there (thanks to Tony Breeds <tony@bakeyournoodle.com>). 3) Point out that guest and host kernel are usually the same. 4) Set the "no checksum" option on the

Hi all, Lguest is a simple hypervisor which runs Linux under Linux, without needing VT hardware. Two people asked if I had a version of lguest which worked on other-than-bleeding-edge-mm kernels, so I did a backport of the latest version to 2.6.21. http://lguest.ozlabs.org/lguest-2.6.21-254.patch.gz See Documentation/lguest/lguest.txt for how to run, drivers/lguest/README for the draft code

The following patches are the latest update of the TSC and hrtimer patches I posted on 29/03. Rusty's original TSC patch has been resynced to the latest lguest repo, as has the hrtimer patch, which also incorporates feedback from Jeremy & Rusty: - Change clock event hrtimer to absolute time. 'now' is captured in the host during the hypercall. - Propagate -ETIME back to the

Hi all, I've been working on lguest64 and in order to do this, I had to move a lot of the i386 specific out of the way. Well, the lguest64 port is still not ready to display, but before Rusty makes too many changes I would like this in upstream so I don't have to keep repeating my changes :-) So this patch series moves lguest32 out of the way for other archs. -- Steve

Hi all, These are the patches I'm planning to submit for 2.6.24. Comments gratefully accepted. Along with the usual cleanups and improvements are Jes' de-i386-ification patches, and a new "virtio" mechanism designed to be shared with KVM (and hopefully other hypervisors). Cheers, Rusty.
