Study Notes
- A hypervisor, also known as a VM manager (VMM), virtualizes the physical components of computer hardware
- It facilitates the interaction between the host machine's physical hardware and the guest machine's virtualized hardware
Type 1 Hypervisors
- Also known as native or bare-metal hypervisors
- Implemented directly on the physical hardware without needing an underlying OS
- Highly performant due to the absence of an OS layer between the hypervisor and physical hardware
- Specialized to meet the requirements of the VMs they host
- Offer a limited set of capabilities beyond VM configuration, provisioning, and management
- VMware ESXi and Microsoft Hyper-V are examples of Type 1 hypervisors
Type 2 Hypervisors
- Also known as hosted hypervisors
- Run as privileged applications on an underlying OS
- Less performant than Type 1 hypervisors due to the additional software layer between the hypervisor and the physical hardware
- The host OS typically does not support the virtualization capabilities of the hypervisor by default, requiring additional driver installations
- Can provide additional processes and services beyond VM management, since the host is running a complete OS
- Oracle VirtualBox and VMware Fusion are examples of Type 2 hypervisors
