There are systems out there that allow dynamic reallocation of physical
resources for virtual systems, so for example if you have 5 VMs running
on a single physical box and the performance spikes on one of the VMs,
the others can be dynamically moved to another physical system even while
running.
Some of the features of large-scale virtualization farms are quite
impressive these days in being able to do that. "Workload management" is
the term I hear our marketing folks (yeah, Novell has marketing folks!)
use.
The server farm that we use for our practical exams currently doesn't do
that, but I'm talking with the implementation team about how we could
dynamically scale if we needed to, and there's a solution available from
a company we bought in 2008 (which of course should make it incredibly
cheap for us to use internally).
