This patch series brings Nested Virtualization to Xen. This is the second patch series with a lot of improvements and fixes thanks to Tim Deegan's review. The patch series: patch 01: add nestedhvm guest config option to the tools. This is the only one patch touching the tools patch 02: change local_event_delivery_* to take vcpu argument. This prevents spurios xen crashes on guest shutdown/destroy with nestedhvm enabled. patch 03: Add data structures for nested virtualization. patch 04: add nestedhvm function hooks, described in XenNestedHVM.pdf patch 05: The heart of nested virtualization. patch 06: Allow switch to paged real mode during vmrun emulation. Emulate cr0 and cr4 when guest does not intercept them (i.e. Hyper-V/Windows7) patch 07: Allow guest to enable SVM in EFER patch 08: Propagate SVM cpuid feature bits to guest patch 09: Emulate MSRs needed for nested virtualization patch 10: Handle interrupts (generic part) patch 11: SVM specific implementation for nested virtualization patch 12: Handle interrupts (SVM specific) patch 13: The piece of code that effectively turns nested virtualization on. Use HVM_PARAM_* this time. patch 14: Change p2m infrastructure to operate with per-p2m instead of per-domain. Combined with patch 15, this allows to run nested guest with hap-on-hap. patch 15: 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.
