As hints and tips for linux under VM are discovered, appropriate
analysis will be done in the form of case studies. The following
case studies can be viewed:
Idle Server Costs:
Reducing Storage Requirements using VM Features:
Operating many linux servers has a cost, even when the servers
are idle. These costs can be reduced, but you may want to evaluate

An experiment was done using a standard 128MB virtual machine.
The working set was immense, paging load was extreme. The
experiment was then performed using a 24MB virtual machine
and a swap set on virtual disk. The elapsed time went from
5 hours to less than an hour, there was no paging, and the
working set was not a problem.
