Pkg xen devel - May 2015 - Bug#785132: Bug#785132: No screen refresh on Windows 8.1 with xen-hypervisor-4.5-amd64

Package: xen-hypervisor-4.5-amd64_4.5.0-1_amd64.deb
Version: 4.5.0-1


Hi,

I use xen with sdl, not with vnc. When I boot on 
xen-hypervisor-4.4-amd64, everything is fine. With Debian or Windows 8.1 
I have a good display,

But when I choose at boot, the xen-hypervisor-4.5-amd64, things go wrong.

If I launch a xen Debian, I get some blur effect on the display.
And when I launch a xen Windows8.1, it is much worse. I only get a black 
screen, with some time, some screen update, BUT the system still boot 
normally. Indeed, I can access to the shared folders, and if I maximize 
and/or minimize the qemu window (on my Debian), I can get a  ?refresh of 
the display?. Thereby I can then see the desktop, but after resizing the 
qemu window, the display is no more refreshed.

Thus, if I move the mouse, the pointer remains motionless, but if I 
maximize and/or minimize the qemu windows, I can see what happened 
really, and where is exactly the pointer.

I tried with a lot of kernel with xen-hypervisor-4.4-amd64, everything 
is ok, but I always get the same issue only with xen-hypervisor-4.5-amd64.

Here a configuration file use for Windows 8.1, that works fine with 
xen-hypervisor-4.4-amd64 but not with xen-hypervisor-4.5-amd64 :

       kernel = "/usr/lib/xen-4.5/boot/hvmloader"
       builder='hvm'
       memory = 2048
       maxmem=3072
       videoram=256
       stdvga=1
       vcpus=4
       name = "Windows8.1"
       vif = ['bridge=br0']
       disk = ['file:/home/zer0/xen/xenwin8.1.img,hda,w']
       acpi = 1
       apic = 1
       hpet=1
       device_model_version = 'qemu-xen'
       boot="c"
       opengl=1
       sdl=1
       vnc=0
       autoballoon=0


Here the latest kernel with which I encounter the problem :

zer0 at debian:~$ uname -a
Linux debian 4.0.0-1-amd64 #1 SMP Debian 4.0.2-1 (2015-05-11) x86_64 
GNU/Linux

Or with

zer0 at debian:~$ uname -a
Linux debian 3.16.0-4-amd64 #1 SMP Debian 4.0.2-1 (2015-05-11) x86_64 
GNU/Linux

Thanks

Are you also changing the qemu version you are using? qemu is
responsible for the majority of the graphics emulation here.

What does ldd /usr/bin/qemu-system-i386 say? How about /usr/sbin/xl?

Note that even if you found a solution, it's still very useful to report
it back to our bug tracker. There might be someone else running into the
same problem, who can be helped with your information.

will close the bug report. If you discover this message later, and this
