-- Start a process in the guest OS, get a virtual address from guest OS
-
-- Translate this address untill we get the physical address on the host OS

-- Software injects an SRAO MCE at that physical address from host OS
-
-- (optionally) Write to the address from the guest, i.e attempt to

 	CONFIG_KVM=y
 	CONFIG_KVM_INTEL=y
-	CONFIG_X86_MCE=y
-	CONFIG_X86_MCE_INTEL=y
-	CONFIG_X86_MCE_INJECT=y or CONFIG_X86_MCE_INJECT=m

-   and following config both on *host* and *guest*
-	CONFIG_ARCH_SUPPORTS_MEMORY_FAILURE=y
-	CONFIG_MEMORY_FAILURE=y
-
-   NOTE: if the host machine doesn't support software error recovery
-   (MCG_SER_P in IA32_MCG_CAP[24]), please apply the patch fake_ser_p.patch
-   under ./patches/
-2. Use ssh-keygen to generate public and privite keys on the host OS,
-   and copy id_rsa and id_rsa.pub from ~/.ssh/ into the testing directory
-   on the host system.
-3. compile and install qemu-kvm
-   the qemu-kvm source can be got from git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git.
-   Before compile qemu-kvm, a patch p2v.patch should be applied. This patch
-   is located under ./patches/
-   Please ensure *SDL-devel* library is installed on the host machine, otherwise
-   only VNC can be used substituing local graphic output.
+2. Create a testing dirctory on host system and put the host test scripts
+   and test tool (page-types) into it.
+   By default, the testing directory is /test.
+3. Use ssh-keygen to generate public and privite keys, and copy them into the

+4. Mount guest image
+5. Create a testing dirctory on guest system and copy guest test script and
+   tools (page-types, simple_process) into it.
+   By default, the testing directory is /test.
+6. Use qemu to start guest system, install page-types and simple_process on
+   guest system.
+     gcc -o page-types page-types.c
+     cd simple_process
+     make

-Subject: [PATCH 2/2] x-gpa2hva, translate guest physical address to host virtual address
-
-Add command x-gpa2hva to translate guest physical address to host
-virtual address. Because gpa to hva translation is not consistent, so
-this command is only used for debugging.
-
-The x-gpa2hva command provides one step in a chain of translations from
-guest virtual to guest physical to host virtual to host physical. Host
-physical is then used to inject a machine check error. As a
-consequence the HWPOISON code on the host and the MCE injection code
-in qemu-kvm are exercised.
-
-v3:
-
-- Rename to x-gpa2hva
-- Remove QMP support, because gpa2hva is not consistent
-
-v2:
-
-- Add QMP support
