How the operating system virtualizes the cpu
Nettet15. apr. 2024 · A virtual machine (VM) is an operating system that shares the physical resources of one server. It is a guest on the host’s hardware, which is why it is also called a guest machine. There are several layers that make up a virtual machine. The layer that enables virtualization is the hypervisor. NettetCommon virtualization layers include the instruction set architecture (ISA) level, hardware level, operating system level, library support level, and application level (see Figure 3.2). 1. Instruction Set Architecture Level. At the ISA level, virtualization is performed by emulating a given ISA by the ISA of the host machine.

Nettet9. apr. 2024 · In traditional virtualization, a hypervisor virtualizes physical hardware. The result is that each virtual machine contains a guest OS, a virtual copy of the hardware that the OS requires to run and an application and its associated libraries and dependencies. VMs with different operating systems can be run on the same physical server.
