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 https://bugzilla.redhat.com/show_bug.cgi?id=1066422 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: https://bugzilla.redhat.com/show_bug.cgi?id=1075139
Gianluca, could you try f20 hosts?
F20 hosts? In which sense? I remained that they are not supported neither in 3.3.x nor in 3.4... It is the reason why my aio install is still on f19.... Or did you mean f20 client? Gianluca
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: qemu 16664 1 48 21:04 ? 00:02:42 /usr/bin/qemu-system-x86_64 -machine accel=kvm -name f19 -S -machine pc-1.0,accel=kvm,usb=off -cpu Opteron_G3 -m 2048 -realtime mlock=off -smp 1,maxcpus=160,sockets=160,cores=1,threads=1 -uuid 55d8b95b-f420-4208-a2fb-5f370d05f5d8 -smbios type=1,manufacturer=oVirt,product=oVirt
