Hi Fabio Fantoni,
 
     Thank you for your advice for building xen=20 unstable.
     Because I have to use debian wheezy as produ= ction=20 distro, I've got to do the test in it.
     Today, I edit Config.mk and write:
QEMU_UPSTREAM_URL =3D git://git.qemu.org/qemu.git
QEMU_UPSTREAM_REVISION =3D master
     Then, the built qemu-xen binary works well.&= nbsp;=20 Therefore, I guess that git://xenbits.xen.org/qemu-upstream-unstable.git&n= bsp;=20 has some very little difference
compared to qemu.git. Maybe your environment cannot repeat  that= =20 problem either, I'd like to provide any useful information to resolve this= =20 problem.

Hi Fabio Fantoni,

I think it is a problem and can be repeated.
     Then, I will summarize my compilation proc= ess=20 here:
     Firstly install debian wheezy 7.5 amd64 an= d=20 necessary build dependency. Then:
2.  install backport version =20 libspice-server-dev libspice-protocol-dev

 3. patch for QXL option
 4. ./configure --prefix=3D/usr&nbs= p;
 5. add spice and usb-redir option&= nbsp;for=20 qemu-xen-upstream
 6. make xen;make=20 tools;make install-xen;make install-tools
 
       To compile qemu 2.0 from=20 qemu.org:
       1. wg= et http://wiki.qemu-project.org/download/qemu-2.0.= 0.tar.bz2
       2.=20 ./configure --enable-xen --target-list=3Di386-softmmu=20 --extra-cflags=3D"-I/usr/src/xen/tools/include -I/usr/src/xen/tools/libx= c=20 -I/usr/src/xen/tools/xenstore" \
        = ;  =20  --enable-spice --enable-usb-redir
       3 .ma= ke;make=20 install
 
 

For fast unstabl= e tests I=20 do this (using my github rebase/m2r-*):
Install of opus, usbredir and l= ibusbx=20 from backports.
Rebuild and install new seabios 1.7.5-1 and spice packa= ges=20 (server 0.12.5-1 and protocol 0.12.7-1) from = sid that=20 contains many fixes (si= mply and=20 fast with git clone of debian repository and debuild).

dpkg -i of xen package in dist (contain both xen and qemu)
A= nd if=20 I need to test newer qemu in development I simply change the qemu git with= =20 mainline in Config.mk.

And for newer=20 production servers I start prepared new xen's debian packages awaiting deb= ian=20 maintainers replies:
https://gi= thub.com/Fantu/pkg-xen/tree/wheezy-backports
Needs=20 also qemu rebuild to use new xen 4.4 libraries (simply and fast with git c= lone=20 of debian repository and debuild).

The= re is=20 also a problem of jpeg-turbo in debian and for have better performances an= d not=20 too many cpu waste I for now solved with:
apt-key adv --recv-keys --key= server=20 keys.gnupg.net E1F958385BFE2B6E
vi /etc/apt/sources.list.d/x2go.list#=20 X2Go Repository (for jpeg-turbo as default and with full -dev package)

Hi Fabio Fantoni,
    
      Thank you for your reply.
      It is really weird.
      I compiled both qemu binary (=20 qemu-upstream in xen and qemu-2.0 from qemu.org website) in th= e same=20 environment,  the binary in xen has the problem while
the other one works well.
      I will check whether wheezy bac= kport=20 has libspice-server-dev and libspice-protocol-dev and try again.

     I also download qemu-2.0 source cod= e from=20 qemu.org, and compiled it by the way mentioned in http://wiki.xen.org/wiki/QEMU_Upstream.
     Then I create win7 hvm with qemu-xen and= =20 /usr/local/bin/qemu-system-i386 respectively.
     The result shows that:
      1 . qemu-upstream used in xen= 4.5=20 unstable still exited when changing screen resolution,
      2.  my self-compiled qemu2.0 = behave=20 normally.
     I think maybe there's still some differe= nces=20 between the two qemu repository.

Use=20 spice from backports or recompile the latest from Sid, wheezy packages a= re too=20 old for newer qemu.
xen already download and compile qemu upstream=20 automatically if you not specify binary in repository.
I also use use= =20 wheezy dom0 with same xen and qemu and same domU and spice guest tools=20 installed automatically resize the windows resolution without problem (e= xcept=20 rare cases when I connect remote-viewer before windows start).Below also reply to other mail.

Hi Fabio Fantoni,

The qemu process suddenly  exited while xl list can still li= st the=20 domU information.

Hi all,
 
Firstly please forgive me if I put this problem in the wrong ma= il=20 list.
However, it seems that xen-users mail list cannot resolve this = QXL=20 problems. Therefore, I have to post QXL problem in devel mail list.<= /DIV>
My problem is as follow:
 
I'm testing QXL for windows HVM, spice works well with stdvga. =
However, when I switch to QXL, qemu exit abnormally:
I specify vga=3D"qxl" and videoram=3D128, using qemu-xen. The w= indows 7=20 boots and automatially switch resolution for me in virt-viewer.
While display and sound transfering very well, if I change disp= lay=20 resolution, the virt-viewer will be suddenly closed and
I check the physical server, the qemu process disappear=20 simultaneously.
Then I switch to wheezy backport qemu 2.0 as device model, the = qemu=20 process will exit as soon as the welcome page appears and at the beg= inning=20 of resolution change.
I tested and found the same bug on both xenbits xen 4.4.1 rc1 a= nd=20 Fantu's Xen 4.5 unstable, this problem exists in both branches.
Is it a known issue or is there any solution for this bug?
Thank you very much!

Thanks for testing spice and qxl and report issue.
= I have=20 spice + qxl working as kvm on xen unstable except this problem:
http://lists.xen.org/archives/html/xen-devel/= 2014-07/msg01021.html

Please=20 post details on your dom0 installation and domU (for example xl=20 cfg,
spice guest tools version ecc...)
About qemu crash try to t= ake a=20 full backtrace with gdb and post it here.

Small help with gdb o= f qemu=20 launched by xl:

Add the line below in domU's xl=20 cfg:
device_model_override=3D"/usr/lib/xen/bin/qemu-gdb"

vi=20 /usr/lib/xen/bin/qemu-gdb # create the file, change the qemu path=20 if

You should in= stall=20 also all needed dbg packages before, spice qemu ecc or
without pack= age=20 should be compiled with debug enabled (for xen and qemu
default in=20 unstable).

The latest qemu crash with spice I saw was in 2.0-rc= =20 solved before 2.0.0
final, your qemu is at least 2.0.0 final?
