Hi,
René met me in person and we got to root cause:
when KMS is enabled for qxl (qxl kernel module is loaded), then bug
occurs - you're
without all agent features (clipboard sharing, arbitrary
resolution, ...).
When the qxl driver runs in UMS mode (with qxl blacklisted - add
module.blacklist=qxl to kernel CLI on reboot), the agent won't crash
anymore but it still won't be able to do resolution changes or monitor
enabling for you
The common bug is in qemu:
Gianluca, could you try f20 hosts?
What should work in all cases are rhel6 guests on rhel6 hosts...

Some prelimianry tests at my side.
oVirt 3.4 on fedora 19 AIO.
Datacenter and cluster configured as 3.4 level
Some packages on it
libvirt-1.1.3.2-1.fc19.x86_64
qemu-kvm-1.6.1-2.fc19.x86_64
vdsm-4.14.6-0.fc19.x86_64
spice-server-0.12.4-3.fc19.x86_64
guest is an updated Fedora 19 system configured based on blank
template and OS=Linux
and
xorg-x11-drv-qxl-0.1.1-3.fc19.x86_64
spice-vdagent-0.14.0-5.fc19.x86_64
Client is an updated Fedora 20 box with virt-viewer-0.6.0-1.fc20.x86_64
If I select the "Single PCI" checkbox in console options of guest and
connect from the Fedora 20 client I don't see at all an option in
remote-viewer to open a second display and no new display detected in
guest.
And lspci on guest indeed gives only one video controller.
BTW: what is this option for, apart the meaning?
If I deselect the "Single PCI" checkbox I get the "Display 2" option
in remote-viewer but it is greyed out.
No new monitor in "detect displays" of guest.
In this last situation I have on host this qem-kvm command line:
