Re: [Spice-devel] Unknown vga type: qxl






Heya!

Hi, 

I found when running spiced QEMU with "-vga qxl" option, it complains 
unknown vga type. My question is: is there any special patch needed to 
support "-vga qxl" option? If no, how to support this? 
BTW: I remove "-vga qxl" when running qemu, it starts up successfully. But 
I'm not sure whether QXL driver is used in this scenario.....?

Unknown vga type: qxl 

Just got the same problem myself.

That's beacuse I forgot to "cd qemu; git checkout -b spice.v13 
origin/spice.v13;" (from the build instruction page)
but since thats old I wrote  v24 instead of 13 after looking at 
http://cgit.freedesktop.org/spice/qemu.

Now it starts with -vga qxl !
 

test2010-2-7:/opt/spice/qemu # ./x86_64-softmmu/qemu-system-x86_64  --help 
|grep vga 
-vga [std|cirrus|vmware|xenfb|none]

Also I checked the spiced QEMU code, there is also no corresponding qxl 
driver information.

Following is my procedure to download and compile spiced QEMU: 
__________________________________ 
I download latest Spiced QEMU code from spice repositories using GIT and 
compile it following the instruction from wiki(
http://www.spice-space.org/page/Building_Instructions): 
http://www.spice-space.org/page/Building_Instructions 
  
cd $SRC_ROOT/qemu
./configure --prefix=$INST_ROOT --target-list=x86_64-softmmu 
--enable-spice
make
