Subject: [Xen-devel] Test report for xen-unstable and qemu-xen

Dom0:
Wheezy 64 bit with kernel from package linux-image-3.2.0-4-amd64
version
3.2.41-2+deb7u2, package blktap-dkms and all dependency packages for
xen, spice and usb redirection.
Seabios 1.7.2-3 and latest spice and usbredir compiled from debian
unstable sources.
-------------------------
/etc/modules
------------
loop max_loop=64
xenfs
xen-evtchn
blktap
-------------------------
git clone git://xenbits.xen.org/xen.git (in this build commit is
bcb49301c21ed69b4e8c164fa215efe9db30621a)
-------------------------
Added some patches:
- tools-configure-qemu-for-spice-and-usbredir
- libxl-Add-spice-vdagent-support-for-upstream-qemu
- tools-firmware-seabios-packaged
- tools: Improve make deb
- vgabios-stdvga.bin custom build from Frediano
- qemu-xen change for support other resolutions:
hw/vga.c: # from Frediano patch
      - if ((val <= VBE_DISPI_MAX_XRES) && ((val & 7) == 0)) {
      + if ((val <= VBE_DISPI_MAX_XRES) && ((val & 1) == 0)) {
-------------------------
./configure --prefix=/usr
-------------------------
make debball

-------------------------
Issues solved from my previous test build report:
-------------
- nested hvm was bugged:

    Before: started test it on windows 7 pro 64 domU on qemu-xen,
    xpmode crashed on install without show error, no error on logs and
havdetection works.

    Now xpmode installs and starts correctly except integration features
    (disks,printers,clipboard sharing) and usb passthrough (of xpmode)
-------------------------

Hi Fabio,
I'm also testing Win7 XP mode in nested VMX environment, but I met some
problems. In the Windows 7 HVM guest, a tool from Microsoft showed
hardware-assisted virtualization is supported, but XP mode showed "hardware-
assisted virtualization is disabled" and it refused to boot XP.
(see the attached 2 pictures to get the two conflicting messages..)

I followed the MS' below doc to set up XP mode.
http://windows.microsoft.com/en-us/windows7/install-and-use-windows-xp-mode-in-windows-7
And, used the tool http://go.microsoft.com/fwlink/p/?LinkId=163321 to check
whether hardware-assisted virtualization is enabled or not.

Test environment:
hardware: Sandy Bridge - EP server
L0: latest Xen 4.3, Dom0 3.10.0, qemu-xen (not traditional)
L1: Windows 7 Enterprise
L2: XP mode

my Win7 guest config file is below; can you give me any hints?
----------------------
builder = "hvm"
name = "jay-hvm-1"
memory = 2048
vcpus = 2
vif = [ '' ]
disk = [ '/home/jay/win7-1.qcow2,qcow2,xvda,w' ]
vnc = 1
stdvga = 1
usb=1
usbdevice='tablet'
nestedhvm=1
----------------------
Have you tried with same xen commit? (bcb49301c21ed69b4e8c164fa215efe9db30621a) or atleast to this that probably have solved my problem: nested vmx: Fix the booting of L2 PAE guest - 49b55619e4923aa1a43b7c027dd3e352575e4e52
