virtual machine
A virtual machine is an electronic phantom that masquerades as a physical host while secretly trapped in a cage of limited resources. It revels in the illusion of freedom under its host OS, yet paradoxically depends on that very overlord for existence. When summoned, it springs to life instantly; when ignored, it idlely consumes space. Its emotional volatility rivals that of humans, crashing at the slightest provocation and spawning endless rebuilds. Forever bound to a cycle of failures and snapshots, it is the quintessential stress inducer for system administrators.
