[Fabio Fantoni <fabio.fantoni@m2r.biz>]

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.
-------------------------
git clone git://xenbits.xen.org/xen.git (in this build commit is 
73f18583dd824f0e49f65149ef603600ce31b8ee)
-------------------------
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

-------------------------
./configure --prefix=/usr --disable-xend
-------------------------
make debball

-------------------------
New issue:
- domU not start with qemu 1.5.1 and more that 2 gb of ram:
   tested on w7 64 bit domU with 4 gb of ram, with built-in qemu 1.3 it 
works,
   while with qemu 1.5.1 doesn't (stops at the beginning, spice client 
show only the lines of seabios version and machine UUID;
   qemu log show nothing more that 2 gb test), while with 2 gb of ram 
works also with qemu 1.5.1
-------------------------

-------------------------
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:

[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)
