I've got a thin client server in which I have a few VM's for users under KVM which I manage through virt-manager.
What I've noticed is if I start a VM guest on a thin client using the command 'virt-viewer ' then the guest is painfully slow to move around. However if on the same thin client I start the same guest VM through virt-manager it's fast.
What are the differences here?
Can I view a VM without having the user load up virt-manager and double click on their VM?
Should I be looking at using splice in virt-viewer instead of VNC which is what I currently use?

You should definitely start using spice, especially if the guest supports QXL, it is much faster than VNC and the picture quality is pretty much what you will get from a normal video card (you'll be able to watch multimedia in the remote session)
