Computer resources are provisioned for a virtual machine based on expected lifespan. After a request to create a virtual machine is received, the virtual machine can be classified into one of a plurality of longevity classes utilizing a machine learning classifier based on data pertaining to the requestor or the virtual machine. The longevity classes capture different lifespans of the virtual machine between when the virtual machine is created and when the virtual machine is deleted. Subsequently, resources for the virtual machine are provisioned from a hardware resource pool of a set of disjoint resource pools specific to the longevity class of the virtual machine.
