Hi, we have been posting all our results on xen-devel too, but we haven't made any progress by now. We are trying to narrow down the problem as much as possible so that we can ask the right question at the right place, any advice is welcome (eg. what tests can be done). Changing the debug level of spice I got this log in my last test: qxl-0: ram/pri: 32 MB [region 0] qxl-0: vram/32: 0 MB [region 1] qxl-0: vram/64: 0 MB [unmapped] (/usr/sbin/xl:3829): Spice-Warning **: reds.c:1923:reds_handle_ticket: Invalid password main_channel_link: add main channel client main_channel_handle_parsed: net test: latency 87.892000 ms, bitrate 603773584 bps (575.803360 Mbps) red_channel_client_pre_create_validate: Error client 0x7fa8f7010170: duplicate channel type 2 id 0 red_channel_client_pre_create_validate: Error client 0x7fa8f7010170: duplicate channel type 2 id 0 inputs_connect: inputs channel client create red_dispatcher_set_cursor_peer: red_dispatcher_set_cursor_peer: red_channel_client_pre_create_validate: Error client 0x7fa8f7010170: duplicate channel type 4 id 0 Qemu invocation: /usr/lib/xen/bin/qemu-system-i386 -xen-domid 2 -chardev socket,id=libxl-cmd,path=/var/run/xen/qmp-libxl-2,server,nowait -mon chardev=libxl-cmd,mode=control -name W7 -k it -spice port=6002,tls-port=0,addr=0.0.0.0,password=prova,agent-mouse=on -device qxl-vga -global qxl-vga.vram_size=65536 -global qxl-vga.ram_size=65536 -boot order=dc -smp 2,maxcpus=2 -device rtl8139,id=nic0,netdev=net0,mac=00:16:3e:49:bb:f1 -netdev type=tap,id=net0,ifname=vif2.0-emu,script=no,downscript=no --global qxl-vga.debug=1 -global qxl-vga.guestdebug=20 -M xenfv -m 1920 -drive file=/mnt/vm/disks/prova/W7.disk1.xm,if=ide,index=0,media=disk,format=raw,cache=writeback -drive file=/mnt/vm/iso/XPSP3PRO.iso,if=ide,index=1,media=cdrom,format=raw,cache=writeback,id=ide-832 _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/spice-devel
