You can remove and add processors to a running guest, and they just 
get hotplugged - you can't go above the number configured. However, 
I'm not aware of any means to start a guest with a different number 
of processors to that configured in the config file. I guess you'd 
have to knock up a simple wrapper script that would start the guest 
and then reconfigure the processors allocated to it.
