Intercept guest reads of MSR_IA32_MCG_CAP and limit the number of memory banks reported to one. This prevents us from trying to read status of non-existent banks when migrated to a machine with fewer banks.

This series of patches fix the mistake for debug exception(#DB), overflow exception(#OF) and INT3(#BP), INTn instruction emulation. Introduce new function vmx_inject_sw_exception() which deliver the software excetion, software interrupt and privileged software exception. Split hardware exception as a seperate function(old function vmx_inject_hw_exception()). Also Passed down intruction length

Changes from v1: - Define new struct hvm_trap to represent information of trap, include instruction length. - Renames hvm_inject_exception to hvm_inject_trap. Then define a couple of wrappers around that function for existing callers, so that their parameter lists actually *shrink*. This series of patches fix the mistake for debug exception(#DB), overflow exception(#OF) and INT3(#BP),

Changes from v1 to v2: - Use a macro to replace the hardcode in patch 1/3. This patchset fixes issues about IA32_VMX_MISC MSR emulation, VMCS guest area synchronization about PAGE_FAULT_ERROR_CODE_MASK/PAGE_FAULT_ERROR_CODE_MATCH, and CR0/CR4 emulation. Please help to review and pull. Thanks, Dongxiao Dongxiao Xu (3): nested vmx: emulate IA32_VMX_MISC MSR nested vmx: synchronize page

Remove visibility of the FFXSR CPUID bit to an HVM guest. This patch allows HVM Windows x64 to install/boot on AMD-V platforms. This patches applies cleanly to xen-unstable 13743. Please apply to xen-unstable/3.0.5. If possible, pls apply to xen-3.0.4-testing. --Tom thomas.woller@amd.com AMD Corporation 5204 E. Ben White Blvd. UBC1 Austin, Texas 78741 +1-512-602-0059

Hi, V6: The only change from V5 is in patch #6: - changed comment to reflect autoxlate - removed a redundant ASSERT - reworked logic a bit so that get_page_from_gfn() is called with NULL for p2m type as before. arm has ASSERT wanting it to be NULL. Tim: patch 4 needs your approval. Daniel: patch 5 needs your approval. These patches implement PVH dom0. Patches 1 and 2

Hello, I''m new to Xen and especially to the hypervisor code. I''m working off a 3.0.4.1 base and have the following questions regarding the memory management code for an x86, 32-bit platform (capable of supporting PAE). I''m doing some research into providing grant table hypercall support from a Windows 2003 HVM. I have made all the necessary changes to allow the
