[Xen-devel] [PATCH 00/12] Nested Virtualization: Overview
Hi! This patch series brings Nested Virtualization to Xen. This is the eight patch series. Improvements to the previous patch submission: - Worked on all items from Tim - Rebased against c/s 22956:8af88ff698ff - Several bugfixes - SVM specific performance improvements: - Implemented shadow vmcb - Implemented vmcb cleanbit emulation The patch series: patch 01: add nestedhvm guest config option to the tools. This is the only one patch touching the tools patch 02: Add data structures for nested virtualization. patch 03: add nestedhvm function hooks. patch 04: The heart of nested virtualization. patch 05: Allow switch to paged real mode during vmrun emulation. Emulate cr0 and cr4 when guest does not intercept them (i.e. Hyper-V/Windows7, KVM) patch 06: When injecting an exception into nested guest, inject #VMEXIT into the guest if intercepted. patch 07: Allow guest to enable SVM in EFER only on AMD. patch 08: Handle interrupts (generic part). patch 09: SVM specific implementation for nested virtualization. patch 10: Handle interrupts (SVM specific). patch 11: The piece of code that effectively turns on nested virtualization. patch 12: Handle nested pagefault to enable hap-on-hap and handle nested guest page-table-walks to emulate instructions the guest does not intercept (i.e. WBINVD with Windows 7). -- ---to satisfy European Law for business letters: Advanced Micro Devices GmbH Einsteinring 24, 85609 Dornach b.

Good progress! Though in very details, there is maybe minor difference, but I vote we start to take the patches so that the next rebase and review can be easier :) Even we can fix later on for those minor issue like other patches did in the past.
