Virtualization Deep Dive: Hypervisors and VM Management Virtualization lets you run several computer systems on one physical machine. The program that makes this possible is a hypervisor. There are two main types: Type 1, which runs directly on hardware, and Type 2, which runs on an existing operating system. Type 1 often delivers better performance and isolation, while Type 2 can be easier to set up for a home lab or small shop. Both types create virtual machines, or VMs, that behave like separate computers with their own CPU, memory, and storage. ...

Hardware Virtualization: A Practical Guide Hardware virtualization lets one computer run several independent operating systems at the same time. A small program called a hypervisor sits between the host hardware and the guest systems. It allocates CPU time, memory, and I/O so each guest thinks it has its own machine. Most modern CPUs include features that make this safer and faster. Intel VT-x and AMD-V give hardware support to switch quickly between guests. Extended page tables (EPT) or similar translations help speed memory access and keep guests isolated. ...

Virtualization Deep Dive: Hypervisors, VMs, and Resource Isolation Virtualization lets you run multiple operating systems on a single physical machine. A hypervisor sits between the hardware and the guests and manages access to CPU, memory, and I/O. This separation provides security, fault tolerance, and flexible capacity. There are two main types of hypervisors: Type 1 runs directly on server hardware, while Type 2 runs inside a host OS. Type 1 is common in data centers and clouds, offering strong performance. Type 2 is common for laptops or testing, with easier setup but slightly higher overhead. ...
