    Hi, Fabio 
      

      Thank you for your advice! I have successfully added the
        patch to xen-4.2.0 and set the parameters as you said.
      

      It works and the client seems to be better than before.
      

      Still, there is a little problem that the screen is upside
        down when the win7 started, exactly the moment the four colorful
        blocks appeared.
      

      After that, the client is stable and everything is OK. Have
        you run into the same problem?

                  Hi,
                    

                    I have tried your patch with xen-4.2.0, but it
                      shows "patch unexpected ends in middle of line" at
                      the end.
                    

                    Is there any problem with that?
                    

                     I can still compile xen and try to add
                      "device_model_args=["-device","qxl-vga"]" in the
                      config file, but it didn't work 
                    

                    with command "xl". The error message is as
                      below, and the log says "RAMBlock "vga.vram"
                      already registered, abort!"
                    

                    Did I miss something?
                    

                    Thank you!

                           Hi, everyone!

                            
                            I am doing research on remote connect with
                            Xen. My host is Fedora 14 and my

                            guest is win7.

                            
                            I have installed spice package and now I can
                            connect to my guest by spice

                            client.

                            
                            Now I want to use QXL, but I don't know if
                            it is supported by the spice in

                            xen-4.2.0.

                            
                            Could anyone help me?

                            
                            Thank you!

                          QXL support in xen is planned for 4.3, you can
                          add manually the actual patch for add it, see
                          attachment.

                          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:

                          (/usr/sbin/xl:3463): Spice-CRITICAL **:
                          red_memslots.c:123:get_virt: slot_id 194 too
                          big, addr=c2c2c2c2c2c2c2c2

                          
                          Some details on one of my latest test: http://lists.xen.org/archives/html/xen-devel/2012-10/msg01820.html

                          Already reported 2 times (on xen) but no
                          reply, I not know if is xen, qemu and/or spice
                          problem.

                          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:(

                          If someone solve this problem can tell me how
                          please?

                          Thanks for any reply and sorry for bad english

                          
              "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 
          
        
    I have different problem, critical with qxl and no problem except
    graphic performance without qxl.

    Can you tell me if you have installer GPLPV driver and/or
    spice-guest-tools-0.2.exe and what write your actual domU
    configuration file please?
