Hi, On paravirt x86 (both 32- and 64-bit), since cset 13998: http://xenbits.xensource.com/xen-unstable.hg?rev/13998 we translate all ptes from being mfn-based to pfn-based when the hardware _PAGE_PRESENT bit is cleared. We do this for PROT_NONE pages, which appear to the HV to be non-present, but which are special-cased in the kernel to appear present (a different bit in the pte remains set for these pages and is caught by the pte_present() tests.) Unfortunately, it looks like recent X servers ar...

The patch deals with the situation which guest OS uses unused page table pages as data pages and write data to them. The pages will still be grabbed by Xen as page table pages, and lots of unnecessary page faults occur. The patch will check if the data guest writes to the page table contains valid mfn or not, if not, we believe it is a data page now and then unshadow the page. The patch

Hi, we have some problems with acpidump running on Xen Dom0. On 64 bit Dom0 it will trigger the OOM killer, on 32 bit Dom0s it will cause a kernel crash. The hypervisor does not matter, I tried 4.1.3-rc2 as well as various unstable versions including 25467, also 32-bit versions of 4.1. The Dom0 kernels were always PVOPS versions, the problems starts with 3.2-rc1~194 and is still in 3.5.0-rc3.

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 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
