Xen users - Jun 2013 - SPICE with Upstream QEMU and qxl VGA cause Windows BSOD

Hi all,

       These days I installed xen 4.3 unstable from source and recompiled qemu
upstream  with spice support.
       After xl create , the windows domU started successfully and spice client
can visit the VDI. However, it display blue screen
before entering the windows welcome screen.
       Is it a bug in current upstream qemu support?
  
       My domU configuration file is:

builder = 'hvm'
memory = '1024'
device_model_version = 'qemu-xen'
device_model_override = '/usr/src/qemu-dm/i386-softmmu/qemu-system-i386'
disk = [ 'tap2:vhd:/srv/win7_noDriver,sda,w']
vif = ['bridge=xenbr0']
boot='cd'
vcpus=4
name = 'UserVM'
usbdevice='tablet'
vnc=1
vnclisten="0.0.0.0"
vncdisplay=1
vncunused = 0
#spice=1
#spicehost='0.0.0.0'
#spiceport=6000
#spicedisable_ticketing=1
#device_model_args_hvm = [ '-vga', 'qxl' ]
videoram = 128
apic=1
pae=1

So what drivers did you loaded ? Why is spice disabled in your
configuration file. Also  I don''t see qxl configured in your config
file.

Hi , jacek,

     Thank you for your reply,
spice=1
spicehost='0.0.0.0'
spiceport=6000
spicedisable_ticketing=1
device_model_args_hvm = [ '-vga', 'qxl' ]
videoram = 128 

   These lines were not comment out when I did my windows domU test.  All
drivers are xl default, and the windows domU did not have any pvdrivers
installed.
   I noticed that if I use spice protocol, I have to use qxl vga option, or the
qemu will exit with error.

I use spice with this
stdvga=1
vga = "stdvga"
videoram=32
shadow_memory = 16
I belive you need
stdvga=0
videoram=128
device_model_args=["-device","qxl-vga"]
or vga = "qxlvga"
I know there is driver for qxl did you install it?

Hi jacek,

     vga='qxl' is not recognized by xen 4.3 xl toolstack, the error
message is:

root@debian:/srv/vm1# xl create 1.cfg       
Parsing config from 1.cfg
Unknown vga "qxl" specified

    Could you give me some suggestions on how to successfully use spice and qxl
graphics on xen ?
    Thank you very much!

Well, the basics of SPICE/qxl support should all be in Xen 4.3. However,
there is a bug triggered by some, well, emulation issues (it''s a SSE
instruction emulation and then communication with qemu, there''s a
thread
on xen-devel about this).

That''s why we have that patch in the tree that jacek is talking about.
In fact, the Xorg qxl driver was triggering right that situation,
leading to a crash.

So, officially, SPICE support is _not_ in 4.3, as that bug was
discovered too late in the release cycle. It''s on the agenda already
for
4.4, though. :-)

However, since I think we''re talking about Windows, aren''t
we?, if
reverting the patch works for you, that would be a fine path to go, I
guess... Perhaps the Windoes qxl driver does not use the critical SSE
instruction.

Regards,
Dario

Oh, really? And you''re using Windows too in such guest? Or, if not, are
you able to start Xorg without qemu crashing? Can I also ask on what
hardware?

Thanks and Regards,

Actually, SPICE support is indeed there, it is _only_ qxl support that
was causing the crash and that has been reverted by the said commit.

Sorry for the mixup. :-P

Dario, George,
would it be possible for somebody to take the information in this thread 
and create a wiki page with a valid config? I added a TODO entry for the 
next docs day, in case this doesn''t happen before.

I believe it is possible, provided we get enough useful information,
i.e., we have a real success report about using SPICE and qxl for
Windows guests... Let''s see.

Might be interesting to ask if Fabio would be up to it, as he probably
knows this better than anyone else (for sure better than me :-D).

I run server 2012 on qemu git. It seems to be working fine. It is bit
slower but it maybe because changes to hard drive the whole cache paches. I
never tested linux with it.

Ok, thanks for sharing this info. :-) When you say ''qemu git''
you mean
qemu-xen, i.e., our snapshot of qemu upstream, right? Or you really use
what they currently have in the official qemu.org git tree?

Mmm... ''slower'' as compared to what, if I can ask?

Ok, that''s fine, it''s good to know that at least Windows works
with qxl,
without causing that SSE issues we''re seeing with Xorg.

Actually, that''s why I''m asking all these question, to try to
figure out
what the functional configuration is, so that we can share it with
others, and make sure we start with the right foot, when working on
re-enabling qxl for everyone in 4.4.

Thanks and Regards,
Dario

I use qemu git . I also use 64 bit qemu with Xen.

Hi Dario，

     Though I had no enough time recompile xen unstable, I made the windows domU
running successfully yesterday.
I noticed that all windows domU image installed under traditional qemu-dm will
have BSOD if switched to upstream qemu, even without qxl vga setting.
My workaround is :
    Firstly boot windows domU image with traditional qemu-dm , install spice
guest tools,
    Then,  switch to upstream qemu with the same windows image, 
    This time , windows domU will boot sucessfully.
    Is there any explanation on this problem? How can I directly boot old images
with upstream qemu.

Switching from qemu-traditional to upstream qemu is the same as switching the 
full motherboard on a physical computer, so a lot of devices will change.
Windows doesn''t like that.

So install Windows with upstream qemu.

What version of Windows are you running?  Are you specifying any 
particular hardware in qemu?

I did a small test where I installed several different versions of 
Windows (including, IIRC, XP, Win7, w2k3, and w2k8) on qemu-traditional 
and then upgraded to qemu-upstream.  The only issue I had was when I had 
specified a network card available in qemu-traditional but not qemu-xen, 
and so when I switched the network card switched and Windows didn''t
have
the right driver installed.  When I just went with the default network 
card everything worked fine.

Hi Dario,

    I made a test on 4.3.0-rc6, spice without qxl works well for win7 now,
whileeven spice without qxl will cause qemu upstream crash  before 4.3.0-rc6 .
    By the way , my self-compiled qemu upstream work well with qxl, it's
really strange.
    However, I found another problem here:
         qemu-upstream cannot boot with a snapshot vhd disk,  it's really
upset.

Spice works good with xen except qxl (for now), also vdagent and
usbredirection works.
About vdagent I posted the libxl patch for support it and for usbredirection
I''ll post also.
About qxl I retried it now on windows 7, with qxl driver have the same
problem of very bad performance and random crash after some time, without
qxl driver (as standard vga) working correctly (was already since last
year).
