Dear All,
I have recently become very interested in SPICE and decided to give it a try
and see if it could replace the NX solution that I have in place.
I have installed Fedora 16 KVM host, where I also upgraded the default spice,
kvm, qemu, virt-manager etc. packages to the latest available at
ftp://ftp.solnet.ch/mirror/fedora/linux//updates/16/x86_64.
I then virtualized a Fedora 16 guest where I am not running any spice-vdagent
at the moment. However, I upgraded xorg-x11-server-Xorg, xorg-x11-server-comon,
xorg-x11-server-Xephyr and xorg-x11-drv-qxl to the latest packages available at
the link above on the virtualized guest.
Through virt-manager, I set up the virtual machine with two QXL devices in
order to get the dual head display to work.
In the virtual guest, I then set up Xinerama via /etc/X11/xorg.conf as follows:
Section"ServerFlags"
Option "Xinerama" "true"
EndSection
Section"Device"
Identifier"QXL0"
Driver"qxl"
BusID "PCI:0:2:0"
Screen 0
EndSection
Section"Device"
Identifier"QXL1"
Driver"qxl"
BusID "PCI:0:8:0"
Screen 1
EndSection
Section"Monitor"
Identifier"Monitor0"
EndSection
Section"Monitor"
Identifier"Monitor1"
EndSection
Section"Screen"
Identifier"screen0"
DefaultDepth 24
SubSection"Display"

EndSection
I then tried to connect via spicec and I successfully got two windows. First
results are pretty good. The primary behaves as primary and so does the
secondary, excellent. Also, it appears that the screen1 is correctly set to be
to the right of screen0.
The problem comes in when I try to move the cursor on the secondary screen. As
soon as I do that the mouse disappears. If I move it out of the secondary
window, it shows up again.. also when I move it back to the primary window.
Additionally, if I open an application on the primary window and then try to
move it to the secondary one, the secondary suddenly becomes usable (cursor
becomes visible) and the primary becomes unusable and behaves like the
secondary used to do at the beginning.
This also happens when running spicec in full screen mode.
As my first objective was to get a proper dual head working I did not install
the spice-vdagentd on the guest machine intentionally. However, since I could
not pin down where the problem lied, I went ahead installing spice-vdagent
0.10.1 on the guest machine.
After doing that, things started to get even worse. For example, when I open
the Gnome menu and try to select some voices, I am no longer able to open
anything as the mouse click appears to be broken. Also, voices don't get
highlighted when I hover over them with the cursor (however, highlighting works
when I use the arrow keys to move between them).
Could anybody shed some light on the above issues and explain to me if I'm
doing anything wrong?
Multi-head should work if you remove the usb-tablet from the vm configuration.
Getting multi-head working with an absolute input device requires some X-server
patches. I've a patched version of the x-server available here:
http://people.fedoraproject.org/~jwrdegoede/xorg-x11-server-f16-multimon/
This is a slightly older version then what is Fedora 16 atm, but I lost my
backported sources, so these binaries are all I have :| These patches are
upstream in the Fedora-17 X-server version so no changes should be needed there
(I did not test this yet).
Besides needing an updated X-server you must also use the agent to get working
absolute input, and you need a newer version then we ship in
F-16. I've just started a build of a newer agent version for Fedora-16 here:
http://koji.fedoraproject.org/koji/taskinfo?taskID=3954056
Using the above X-server + agent rpms should fix your issue.

Hans
