Fix PAE shadow on a machine with RAM above 4G on x86_64 xen. Currently, on a machine with RAM above 4G, we can not run 32bit VMX guest on x86_64 xen, the root cause is that the PAE page table PDPT must below 4G, this patch fixes this issue. Also did some cleanup. Signed-off-by: Xin Li <xin.b.li@intel.com> Signed-off-by: Jun Nakajima <jun.nakajima@intel.com>

Currently, Xen does not support injecting an NMI to HVM guest OS. Adding this feature is necessary for those softwares which depend on NMI to function correctly, such as KDB and oprofile. The attached patch allows NMI to be injected to guest OS in NMIP capable platforms. It also enables to queue an NMI and then inject it as soon as possible. Signed-off-by: Haitao Shan

The "APIC-register virtualization" and "virtual-interrupt deliver" VM-execution control has no effect on the behavior of RDMSR/WRMSR if the "virtualize x2APIC mode" VM-execution control is 0. When guest uses x2APIC mode, we should enable "virtualize x2APIC mode" for APICV first. Signed-off-by: Jiongxi Li <jiongxi.li@intel.com> diff --git

Attached are the patches to support super page with EPT. We only support 2M size. And shadow may still work fine with 4K pages. The patches can be split into 3 parts. Apply order is as attached. tool.diff To allocate 2M physical contiguous memory in guest except the first 2M and the last 2M.

This patch implements a new mechanism to buffer the MMIO_WRITE and PIO_WRITE packet in a queue, and then submit them to qemu-dm in batch. This could save a lot of domain switch time. We implement this as a generic one to do ioreq in batch. However, we only use it to batch the MMIO_WIRTE request for stdvga(0xA0000-0xC0000) in order to solve the win2k boot issue for hvm domain.

With this patch, x86 and x86-64 share ioport.c, fixing LTP iopl and ioperm testcase failures (on both). We found an iopl testcase failing even on x86 xenlinux. Now x86-64 xenlinux should have the same results regarding the LTP testcases (as far as we tested).

All, We met several system failures on different hardware platforms, which are all caused by VT-d fault. err 1: disk is corrupted by VT-d fault on SATA. err 2: Dom0 kernel panics at booting, which is caused VT-d fault on UHCI. err 3, Dom0 complains disk errors while creating HVM guests. The culprit would be changeset 19054 "x86_64: Remove statically-partitioned Xen heap.". Detailed

Is it intentional that - under SVM, 32-bit guests can freely set EFER.LME - under VMX, 32-bit guests can''t access EFER at all? Thanks, Jan _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

HVM balloon driver or something, that''s under development, may decrease or increase the machine memory that is taken by HVM guest; in IA32/IA32e host, now Qemu maps the physical memory of HVM guest based on little blocks of memory (the block size is 64K in IA32 host or 1M in IA32E host). When HVM balloon driver decreases the reserved machine memory of HVM guest, Qemu should unmap the
