On top of tht is the major rework of lguest, to use PCI and virtio 1.0, to double-check the implementation. Then comes the inevitable fixes and cleanups from that work.

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 guest timer framework - Use the API-provided delta via set_next_...

Christoph Hellwig said runs sparse: 1) page_tables.c unnecessary initialization 2) Change prototype of run_lguest and do cast in caller instead (when we add __user to cast, it runs over another line). Al Viro pointed out the ugly cast in push_lguest_stack(): 3) Stick with unsigned long for arg, removes 4 casts in total. Most importantly, I now realize that Christoph's incorrect ranting about lgread_u32...

...feedback from CC'd was applied to excellent effect (and the advice from Matt Mackall about my personal appearance is best unrequited). The patch is split in 5 parts to correspond with the 9 parts Andrew sent out before, but here's the summary: 1) Sparse (thanks Christoph Hellwig): - lguest_const can be static now - lguest.c should include "lguest_bus.h" for lguest_devices declaration. - page_tables.c unnecessary initialization - But the cost was high: lots of __force casts 8( 2) Jeff Garzik - Use netdev_priv instead of dev->priv. - Check for ioremap f...

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 Docu...
