<div>I have tried your patch with xen-4.2.0, but it shows "patch
unexpected ends in middle of line" at the end.</div>
<div><br>
</div>
<div>Is there any problem with that?</div>

I can still compile xen and try to add
"device_model_args=["-device","qxl-vga"]" in the config file,
but it didn't work </div>
<div><br>
</div>
<div>with command "xl". The error message is as below, and the log
says "RAMBlock "vga.vram" already registered, abort!"</div>
<div><br>
</div>
<div>Did I miss something?</div>

<div>Thank you!</div>

Hi, everyone!<br>
<br>
I am doing research on remote connect with Xen. My host is
Fedora 14 and my<br>
guest is win7.<br>
<br>
I have installed spice package and now I can connect to my
guest by spice<br>
client.<br>
<br>
Now I want to use QXL, but I don't know if it is supported
by the spice in<br>
xen-4.2.0.<br>
<br>
Could anyone help me?<br>
<br>
Thank you!<br>
<br>

QXL support in xen is planned for 4.3, you can add manually
the actual patch for add it, see attachment.<br>
I tried it many times, months ago was working but xorg on
linux domU not started and on windows domU had blu screen
refered to qxl driver, recently starting domU with spice and
qxl caused qemu crash with this error on log:<br>
(/usr/sbin/xl:3463): Spice-CRITICAL **:
red_memslots.c:123:get_virt: slot_id 194 too big,
addr=c2c2c2c2c2c2c2c2<br>
<br>
Some details on one of my latest test: <a href="http://lists.xen.org/archives/html/xen-devel/2012-10/msg01820.html" target="_blank">http://lists.xen.org/archives/html/xen-devel/2012-10/msg01820.html</a><br>
Already reported 2 times (on xen) but no reply, I not know
if is xen, qemu and/or spice problem.<br>
Is now a year I try to have spice with qxlrunning on xen, I
have done numerous tests and reports, some bugs/changes on
xen and qemu have been made, but are not yet sufficient to
have qxl functioning as of kvm:(<br>
If someone solve this problem can tell me how please?<br>
Thanks for any reply and sorry for bad english<br>

"patch unexpected ends in middle of line" at the end is not a
problem, you can continue to build xen, about xl configuration file
remove device_model_args, videoram, set vnc=0, qxl=1 and other spice
parameters you need
