Which feature of virtualization allows multiple operating systems to run on a single hardware platform?

The ability for multiple operating systems to run on a single hardware platform is primarily facilitated by resource pooling. This concept allows virtualization technology to allocate and manage physical resources from the hardware efficiently across different virtual machines. Resource pooling effectively abstracts the underlying hardware, enabling various operating systems to share the same hardware resources while maintaining their own environments.

By utilizing resource pooling, the hypervisor can dynamically allocate CPU, memory, and storage resources to different virtual machines as needed. This results in improved utilization of hardware resources and flexibility in how those resources are employed. While isolation and scalability are also important characteristics of virtualization, they relate to how virtual machines interact with each other and how the environment can grow, respectively, rather than directly explaining the capability to run multiple operating systems on one platform. Abstraction involves separating the software from the hardware but does not specifically address the concurrent operation of multiple OS instances on a single system.
