[ovirt-users] Getting Spice agent to work properly with Ubuntu 14.04.2

I'm configuring a new Ubuntu desktop VM, with 14.04.2. I've installed ovirt-guest-agent and spice-vdagent. But when I connect to the console I get 640x480 resolution only. Resizing the console window does not change the underlying desktop resolution. I saw in the Wiki that I should install xserver-xorg-video-qxl, but when I attempt to do so the installation fails, saying I have some broken dependencies: The following packages have unmet dependencies: xserver-xorg-video-qxl : Depends: xorg-video-abi-15 Depends: xserver-xorg-core (>= 2:1.14.99.902) E: Unable to correct problems, you have held broken packages. If I try to install xorg-video-abi-15 or xserver-xorg-core, it also fails. They depend on a bunch of packages which say "not going to be installed". Anybody know what's going on here? Is the Ubuntu repository broken? Or maybe the ovirt guest agent repository (I followed instructions here: http://www.ovirt.org/How_to_install_the_guest_agent_in_Ubuntu)? -Bob
