Hi,
I'm trying to virtualize my Fedora 20 workstation on oVirt 3.4 with 2
screens.
No matter if I choose Server or Desktop and operating system Linux or
RHEL 6.x x64 (surprisingly Fedora is missing in the list) my Fedora
guest (or better say LXRandR) only recognizes 1 monitor.
ps -ef | grep myvm shows me that there are 2 monitors (or at least I
think that I can interpret the output this way):
-vga qxl -global qxl-vga.ram_size=134217728 -global
qxl-vga.vram_size=33554432
Does anyone know how I can make my Fedora guest work with 2 screens?
Thanks!

Probably you already visited this:
http://www.ovirt.org/Features/SPICERelatedFeatures#Multi_Monitor_support_...
but from the text is not so clear to me if it is completely doable or
not in 3.4 ...
The page refers to Xinerama in need to be configured inside the guest
I don't know if for QXL device and fedora 20 one has to trick with
xorg.conf or not putting something like
Section "ServerLayout"
Identifier "Layout0"
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
Option "Clone" "off"
Option "Xinerama" "on"
Screen 0 "Screen0"
Screen 1 "Screen1" Below "Screen0"
EndSection
Does your Xorg.0.log gives any useful information regarding the two
devices and anythng about Xinerama?

Hi Gianluca,
Thanks a lot for your answer.

No, I didn't - thanks a lot for the link.
As it says it's for oVirt 3.1 it properly should be in oVirt 3.4.
but from the text is not so clear to me if it is completely doable or
not in 3.4 ...

Hurra - we're in year 2014 and Linux is still not able to configure 2
screens with a simple click. :(
Btw, I don't even find a config file for ServerLayout section in /etc/X11.
Section "ServerLayout"
Identifier "Layout0"
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
Option "Clone" "off"
Option "Xinerama" "on"
Screen 0 "Screen0"
Screen 1 "Screen1" Below "Screen0"

In Xorg.0.log I can see the following:
qxl(0): Output Virtual-0 has no monitor section
qxl(0): Output Virtual-1 has no monitor section
qxl(0): Output Virtual-2 has no monitor section
qxl(0): Output Virtual-3 has no monitor section
<snip>
qxl(0): Output Virtual-0 connected
qxl(0): Output Virtual-1 disconnected
qxl(0): Output Virtual-2 disconnected
qxl(0): Output Virtual-3 disconnected
Whatever this mean. No clue about Xorg - should install X on my servers
to get more practice in it :)
Btw,
in Remote Viewer I can choosee View - Display and select Display 2.
In second remote viewer windows I see "Waiting for display 2..." - os it
seems that at least the port is for second display is open on my host.
So I guess oVirt is working fine and the question about the dual screen
mode can be answered best on Spice or Fedora mailing list?

Hi,
No configuration nor Xinerama should be needed. Just make sure you have
spice-vdagent package installed, spice-vdagentd service running and two
spice-vdagent processes running (one for *dm, one for your user
session). Then enable other monitors in virt-viewer: check View ->
Displays -> Display N.
Xinerama is an old hackish means to multimonitor for linux guests with
numerou disadvantages so please avoid that. If you really really want to
use xinerama, then switch your OS type to Windows and your VM will get
multiple qxl devices that xinerama depends on.

PS: if the spice-vdagent package is installed in the guest and the
processes mentioned above are not running, it is a bug that should be
reported.

No Xinerama sounds great!
vdagent was already installed and is running:
$ ps -ef | grep vdagent
root 729 1 0 17:51 ? 00:00:00 /usr/sbin/spice-vdagentd
rkoch 1487 1 0 17:52 ? 00:00:00 /usr/bin/spice-vdagent
When I open a second monitor in virt-viewer it says "Waiting for display
2..." and my vdagent services stops:
$ ps -ef | grep vdagent
root 729 1 0 17:51 ? 00:00:00 /usr/sbin/spice-vdagentd
In /var/log/messages I can see the following:
Apr 8 17:53:07 pc02 kernel: [ 128.497232] input: spice vdagent tablet
as /devices/virtual/input/input5
Apr 8 17:53:07 pc02 kernel: input: spice vdagent tablet as
/devices/virtual/input/input5
Apr 8 17:53:11 pc02 spice-vdagentd: closed vdagent virtio channel
My vm has now the following settings:
OS: Linux
Optimized for: Desktop
Monitors: 2
Single PCI: activated

I don't want to use it and hack in Xorg config files :)
