The process of provisioning guest and host virtualization is considered:

Resource conservation refers to reducing or minimizing consumption of resources, which is a potential benefit of virtualization but does not describe the provisioning process itself.

Resource allocation is the process by which a hypervisor divides and assigns a physical host's compute resources - CPU cycles, RAM, network bandwidth, and storage I/O - among one or more guest virtual machines. Provisioning a guest VM inherently requires specifying how much of the host's physical resources that guest will receive and be able to use.

Resource partition describes dividing a resource into segments, which is a component of allocation, but is not the standard industry term for the full provisioning process of guest and host virtualization.

'Resource method' is not a recognized or standard term in virtualization or IT infrastructure nomenclature.
