[Spice-devel] Does spice in xen-4.2.0 support QXL?

[Qian Hu]

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!
