KVM is included, you just have to select it. There is a loyal following of
Xen in the community, but I use KVM for my servers. I'm often called 'dumb'
for even talking about KVM, but I like it. (and I'm not saying, nor have I
ever said, that KVM is better than Xen)

I assume you're using VNC to connect? It can be painfully slow with some vnc
clients, and workable for basic stuff with others.

Using MS remote desktop to connect to a VM running Windows works pretty
well, but not when you're trying to view anything with graphics. (like
watching videos)

There's the SPICE protocol which supposedly handles these problems, although
I haven't tried it yet.

It would be nice if you could run your OS in a VM, then use some tablet with
a huge screen to connect to the VM and not be able to notice a difference in
speed. I think that's a ways off in the future, however.
