Ok.. so perhaps it is not the appliance itself :)

qemu means you are running kvem _or_ you are running emulated. Emulated 
would be very slow. When the machine is running, execute the following:

ps -ef | grep qemu

Tell me what you get.

Also.. look at this page:

http://fedoraproject.org/wiki/Getting_started_with_virtualization#System_requirements

And tell me if you are can support full-virt or para virtualized guests.
