[Gllug] kvm and slow X performance

Generally vdi desktop applications are going to be slow over higher latency
links. Even mature tools like citrix are hopeless on high latency links. My
use case has the desktop vm and the client on the same machine.
The best tool for high latency links is web applications being viewed by a
web browser or small apps like android apps. They keep the user gui and
interactivity code all on the client and make backend calls to web sites.
This keeps the app feeling interactive.
