in what sense, just a performance you mention below, or something else?
I'm
used to use spice with virt-manager, and I always have been pleased
with it.

What hosts and clients do you use, what is your network environment?
ubuntu
spice-client-gtk (0.22) for the client side, and my hosts (latest
intel CPU and 128 GB of RAM) are centos 7.1 one connected to a FC
storage domain. The network is a gigabit one. I set my vms with 2GB of RAM.
When you say centos guests, you mean centos 6 or centos 7?
both. I also tested fedora 22 but I supposed that default gnome 3 shell
effects could be the reason of the slowness.

Ovirt is an awesome product, and I've been used to be pleased with its
great integrated quality tools, that's why I'm supposed to mistake in my
configuration.
I don't know the vdi part, but problematic is not the same compared to
the server virtualization. User should have a very good interface
experience, integrating fluidity and multimedia capabilities.
Sound redirection is okay with no latence, USB redirection works great,
but watching a youtube video is painful.
The same when moving a simple gui window, there is a big latence.
In comparison, direct RDP session on windows servers gives entire
satisfaction in graphic rendering.
Please tell me if I do or say something wrong.
Thank you for your job.
