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

[Fabio Fantoni <fabio.fantoni@xxxxxxx>]

Dom0:
Wheezy 64 bit with kernel from package linux-image-3.2.0-4-amd64 version 
3.2.46-1 and all dependency packages for xen, spice and usb redirection.
Seabios 1.7.3-1, qemu 1.5.0+dfsg-5 (1.5.1), spice 0.12.4-0nocelt1 and 
usbredir 0.6-2 compiled from debian unstable sources.
-------------------------
/etc/modules
------------
loop max_loop=64
-------------------------
git clone git://xenbits.xen.org/xen.git (in this build commit is 
6072b7c808043b6886c33f896e06fc32ee28346e)
-------------------------
Added some patches:
- tools-configure-qemu-for-spice-and-usbredir
- libxl-Add-spice-vdagent-support-for-upstream-qemu v3
- libxl: usb2 and usb3 controller support for upstream qemu v4
- tools-firmware-seabios-packaged
- tools: Improve make deb v3
-------------------------
./configure --prefix=/usr
-------------------------
make debball

Note:
I tested both upstream qemu of xen git and debian unstable packages.
On this test I removed blktap2 (after see disabled for next version of 
xen debian package), no regression found with qdisk and performance 
significantly improved. One benchmark result on windows 7 64 bit domU on 
attachment.
-------------------------
Old issue:
- Network is not working after restore on Windows domU with qemu-xen and 
gplpv
  Workaround: fixed mac address
-------------
- Starting xendomain with "xl create" show some debug options:
  Starting auto Xen domains: W7.cfgxc: info: VIRTUAL MEMORY ARRANGEMENT:
  Loader:        0000000000100000->000000000019eb68

  1GB PAGES: 0x0000000000000000
[done].
I think it is would be better hiding them here
-------------
- on W7 pro 64 bit domU error in the begin of qemu log, while domU seem 
to work:
xc: error: linux_gnttab_set_max_grants: ioctl SET_MAX_GRANTS failed (22 
= Invalid argument): Internal error
xen be: qdisk-832: xc_gnttab_set_max_grants failed: Invalid argument
-------------
- nested hvm was bugged: 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 install and start correctly except integration features
  (disks,printers,clipboard sharing) and usb passthrough (of xpmode)
