![]() ![]() They are also used in cloud computing platforms, enabling efficient resource allocation and isolation between guests. They are commonly deployed in server virtualization scenarios, consolidating multiple physical servers into a single host machine. Type 1 hypervisors are made and used extensively in enterprises where scalability, availability, high performance, and security are crucial. This makes them more expensive both to implement and maintain than type 2 hypervisors. As they operate at a low level, they require expert knowledge to configure and manage effectively. The biggest drawback of type 1 hypervisors is their complexity and potential for compatibility issues. In addition, advanced features like live migration allow VMs to be moved between physical servers without disruption. In the event a guest VM is attacked, the guest is isolated to ensure other VMs on the same hardware are not affected. They also provide advanced security, thanks to each guest VM running on its own OS. ![]() This lets them maximize server resources by efficiently managing multiple VMs simultaneously. Type 1 hypervisors offer excellent performance due to their direct hardware access, meaning they are not competing for resources with other software. Each VM has its own virtual resources, including vCPU, memory, and storage abstracted from the underlying hardware, and operates independently. Instead, each OS is installed and run on its own respective VM, each of which is managed by the hypervisor. The hypervisor manages the hardware resources and directly hosts multiple VMs without needing a separate underlying OS. ![]() Type 1 hypervisors: Bare metalĪ type 1 hypervisor, also known as a native or bare-metal hypervisor, runs directly on the system’s underlying hardware. Here are some pros and cons of each, along with recommended use cases and examples. There are two types of hypervisors: type 1, also known as bare-metal hypervisors, and type 2, also known as hosted hypervisors. Bottom line: Deploying hypervisor servers in the enterprise. ![]()
