You should have a working framebuffer console on qxldrmfb before trying to get X11 going.I tried on Fedora19 minimal installation and with qxl the text console is working and lsmod show also qxl.Good, so the kernel driver is running fine.Is this your intended?Yes.#3 qxl has a bunch of tracepoints. Enable them, then compare xen results with kvm/tcg results to see where things start going wrong.I enabled qxl debug with these qemu paramters: -global qxl-vga.debug=1 -global qxl-vga.guestdebug=20debug=1 doesn't do much, most is in tracepoints these days. I'm using the stderr tracer most of the time (enable it using configure). Then you can turn on qxl_* either in monitor (trace-events command) or via -trace events=<file-with-event-names>. Thanks for reply, I used trace of qxl_* instead of -global debug options (is it right or must I maintain also global qxl debug option?). On attachment the new qemu log of windows 7 test with qxl vga. The test was made as for below: I tried also W7 domU on xen with spice-guest-tools-0.65.exe and qxl: domU starts, loads correctly the DE, vdagent and mouse are both working, but screen refreshing is very lagging (also only open of start menu). Can you check the log to see if there are strange things to fix also on spice and/or qemu? Thanks for any reply. I tried to test Fedora19 on debian sid kvm host same qemu version (1.6) on both sides but with qxl fails to start the DE, also in fallback mode. Probably there are also regression on qemu and/or spice about qxl.I'm not aware of any regressions. I'd suggest to try latest spice-server release. I double checked and is already to latest version: http://packages.debian.org/sid/libspice-server1 HTH, Gerd Attachment:
