Hi all, I am facing a problem with Spice: if I enable spice as the display model, everything works (display, mouse), but the keyboard does not work. If I use VNC as the model, the keyboard works, but the display has a slow refresh rate.

Any ideas on what it may be wrong? Running fedora 16, will updates installed. Regards, George _______________________________________________ virt mailing list virt(a)lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/virt

Dear Alon, I have placed the results here: http://server.intellitech.gr/spice.cap It does look like a binary file. Is it supposed to be this way?

Is it supposed to be this way? Yes. Actually the file ending should have been pcap. It's a standard format for network captures which I can read with wireshark with the spice dissector and look for the key presses, just trying to figure out if it's a problem at the client side or server/qemu side.

I did the following: a) Installed wireshark, run as root (couldn't manage to run it as a normal user, even after adding the user to the wireshark group - perhaps a selinux denial).

b) Started capture on lo. I waited for a while, nothing got captured.

c) I started virt-manager, and then started the VM. Nothing captured. d) I displayed the VM in virt-manager viewer, and capture started. I waited until the capture log stopped having new entries. e) I verified that each time I move the mouse, packets were captured. f) I verified that when I press keys, again packets are logged. I have saved the capture from inside wireshark here: http://server.intellitech.gr/spice.cap.bz2 Towards the end of the capture, is only key presses, and the mouse movement outside the VM viewer, to stop capturing. I haven't managed to find the spice dissector in wireshark (I got through yum).

I have a PC. I have started a VNC server on the pc. I run virt-manager inside this vnc server. I run the VM from this virt-manager (so virt-manager & VM run in the pc that the vnc server runs). And from a second pc, I have a vnc client, that I see all these.

I have uploaded a capture from em1 here: http://server.intellitech.gr/spice-em1.cap.bz2

Yes, wireshark runs on the same pc as the vnc server, virt-manager & the VM. I control it through a vnc client, from another pc. > I don't see any >TCP connections being created, as I would expect if virt-manager starter >the spice connection after the capture is started. Can you please make >sure virt-manager is closed before you start the capture? I have rebooted the pc, I have started wireshark, and then started virt-manager & the VM. The VM booted (windows 7 64 bit), I pressed a few keys, then I opened the start menu, some more key presses, and finally I stopped the VM (normal shutdown from windows). All this interaction is here: http://server.intellitech.gr/spice-wholevm.cap.bz2 If something is still missing, I think that it is possible it does not exist.

Hi all, I am facing a problem with Spice: if I enable spice as the display model, everything works (display, mouse), but the keyboard does not work. If I use VNC as the model, the keyboard works, but the display has a slow refresh rate. Any ideas on what it may be wrong? Running fedora 16, will updates installed.

Have you tried adding the "EvTouch USB Graphics Tablet" input device, along with the normal mouse?
