I'm trying to implement basic spice support on xen pv domUs.
Test seems ok on Ubuntu 12.04 pv domU except mouse which is not visible.
I also tried agent-mouse=off on qemu spice options but is not working or
maybe spicy (from spice-gtk 0.20) has problem in this case (option to
grab mouse is already enabled).
I can't add vdagent for now on pv because it hasn't pci support.
Are there xen parts which may give problem with mouse or couldn't be a
xen related problem?
Qemu parameters on my test was:

I have also another question for qemu/spice developer: I tried to change
qemu -vga parameter to -device but isn't working and I not found nothing
on docs or man. Is xenfb available with new qemu parameter -device?
Thanks for any reply.

Given that PCI and USB buses are both missing in PV guests, I guess that the issue might be that spice assumes that the mouse is somehow emulated by a USB device? I think it could be difficult to disentangle spice support from usb/pci. You could try to run only the mouse part of the xenfb protocol to get mouse support. BTW where are you running the spice backend? Is it a standalone daemon? > > Qemu parameters on my test was: > > > libxl: debug: libxl_dm.c:1282:libxl__spawn_local_dm: Spawning device-model > > > /usr/lib/xen/bin/qemu-system-i386 with arguments: > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: > > > /usr/lib/xen/bin/qemu-system-i386 > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -xen-domid > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: 19 > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -chardev > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: > > > socket,id=libxl-cmd,path=/var/run/xen/qmp-libxl-19,server,nowait > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -mon > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: > > > chardev=libxl-cmd,mode=control > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -nodefaults > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -xen-attach > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -name > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: PRECISE > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -k > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: it > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -spice > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: > > > port=6002,tls-port=0,addr=0.0.0.0,disable-ticketing,agent-mouse=off > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -vga > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: xenfb > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -M > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: xenpv > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -m > > > libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: 1025 > > > > > I have also another question for qemu developers: I tried to change qemu > > -vga parameter to -device but isn't working and I not found nothing on docs > > or man.

About qxl vga (optimal for increase spice performance and more resolutions support), seems that requires other modifications/fix xen side that are not able to do :( Latest debug that I tried if can be useful: http://lists.xen.org/archives/html/xen-devel/2013-10/msg00016.html Waiting for news about it I'm trying to implement at least the basic spice support on pv for use spice for both hvm and pv (atleast the part of domUs maintenance). >>>>> Qemu parameters on my test was: >>>>>> libxl: debug: libxl_dm.c:1282:libxl__spawn_local_dm: Spawning >>>>>> device-model >>>>>> /usr/lib/xen/bin/qemu-system-i386 with arguments: >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: >>>>>> /usr/lib/xen/bin/qemu-system-i386 >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -xen-domid >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: 19 >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -chardev >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: >>>>>> socket,id=libxl-cmd,path=/var/run/xen/qmp-libxl-19,server,nowait >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -mon >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: >>>>>> chardev=libxl-cmd,mode=control >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -nodefaults >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -xen-attach >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -name >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: PRECISE >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -k >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: it >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -spice >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: >>>>>> port=6002,tls-port=0,addr=0.0.0.0,disable-ticketing,agent-mouse=off >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -vga >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: xenfb >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -M >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: xenpv >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: -m >>>>>> libxl: debug: libxl_dm.c:1284:libxl__spawn_local_dm: 1025 >>>>> I have also another question for qemu developers: I tried to change qemu >>>>> -vga parameter to -device but isn't working and I not found nothing on >>>>> docs >>>>> or man.
