Because of legacy-induced blindness, I insisted on separately building the hypervisor.S switcher code (which is mapped at 0xFFC0000 in host and guest). However, the lguest64 patches showed the error of my ways: it has no relocations, so it can be linked into the module like normal then remapped. The only downside is that we can no longer use sizeof(hypervisor_blob), so we need to allocate our

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

[ Changes since last version. - Move lg.h to include/asm instead (suggested by Rusty Russel) - All steps of the series compiles (suggested by Stephen Rothwell) - Better ifdef header naming (suggested by Stephen Rothwell) - Added Andi Kleen to CC (forgot to on V1) ] 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

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, 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.

Hi, this version requires that host and guest have the same PAE status. NX cap is not offered to the guest, yet.

Hi, For some days I have been looking for the bug that causes an easily reproducible oops in the guest when I apply my PAE support _draft_ patch (appended at the end of this mail) to lguest. This is the oops: Setting kernel variables...done. Will now mount local filesystems:. Will now activate swapfile swap:done. Cleaning /tmp... [ 84.749676] BUG: unable to handle kernel NULL pointer
