[Fabio Fantoni <fantonifabio@xxxxxxxxxx>]

Starting domU with spice + qxl qemu always crashes.

Dom0:
Wheezy 64 bit with kernel from package linux-image-3.2.0-4-amd64 version 3.2.32-1, package blktap-dkms, spice 0.12.0, spice protocol 0.12.2 and all dependency packages for xen
hg clone http://xenbits.xen.org/hg/xen-unstable.hg (in this build changeset is 26152:d1d05cb59a76)

SEABIOS_UPSTREAM_URL ?= git://code.coreboot.org/seabios.git
SEABIOS_UPSTREAM_TAG ?= master
-------------------------
Added some patches:
- tools: Improve make deb
- Add qxl vga interface support v5
- tools: Compile qemu-xen with spice
-------------------------
./configure
-------------------------
make deb

Qemu upstream: commit ce34cf72fe508b27a78f83c184142e8d1e6a048a
Seabios upstream: commit 9600c800ac2a6b34a9993d99e7d3d4f7301e9265

Are there some new seabios settings that I'm not aware of in order to get xen and spice with qxl functioning. See build log on attachment for details.

Here the configuration of the domU tested:

Someone can help to solve the problem please?
If you need other information and/or test tell me and I'll do it.
