virt-manager

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 start 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?
