Understanding Type 3 Hypervisors
What are Type 1, 2, and 3 Hypervisors?
Hypervisors, also known as virtual machine monitors (VMMs), are software programs that create and manage virtual machines (VMs). The type of hypervisor used can greatly impact the performance and security of the virtual environment. There are three main types of hypervisors: Type 1, Type 2, and Type 3.
Type 1 hypervisors run directly on the host’s hardware, providing a layer of abstraction between the hardware and the guest operating systems running on the VMs. This type of hypervisor is also known as a “bare-metal” hypervisor, as it is installed directly on the physical server hardware. Type 1 hypervisors are often used in enterprise data centers and cloud computing environments because they offer high performance and scalability.
Type 2 hypervisors, on the other hand, run on top of a host operating system, creating a virtual environment within the OS. This type of hypervisor is often used on personal computers and laptops, as it does not require any additional hardware or modifications to the host OS. However, Type 2 hypervisors can be less efficient than Type 1 hypervisors, as they introduce an additional layer of abstraction between the hardware and the guest operating systems.
Type 3 hypervisors, also known as “hosted” hypervisors, run on top of a host operating system and create a virtual environment within the OS. Unlike Type 2 hypervisors, Type 3 hypervisors are designed to run multiple VMs simultaneously, each with its own guest operating system. Type 3 hypervisors are often used in server virtualization environments, as they offer high scalability and flexibility.
Overall, the choice of hypervisor type depends on the specific needs and requirements of the virtual environment. Type 1 hypervisors are ideal for high-performance environments, while Type 2 hypervisors are suitable for personal computers and laptops. Type 3 hypervisors are best suited for server virtualization environments, where multiple VMs need to be run simultaneously.
How does a Type 3 Hypervisor differ from other types?

This allows for more granular control over the virtual environment, as well as better isolation between virtual machines.
Control Over Hardware Resources
One of the key benefits of using a Type 3 hypervisor is the ability to control all hardware resources. This means that the hypervisor can allocate resources such as CPU, memory, and storage to each virtual machine as needed, ensuring that each virtual machine has access to the resources it needs to run smoothly. This is in contrast to Type 1 and Type 2 hypervisors, which may not have direct access to all hardware resources and may need to rely on the guest operating system to manage them.
Granular Control Over Virtual Environment
In addition to controlling hardware resources, Type 3 hypervisors also provide granular control over the virtual environment. This means that administrators can configure each virtual machine in a way that meets the specific needs of the application or workload running on it. For example, an administrator could configure one virtual machine to have a high amount of CPU and memory resources for a high-performance workload, while configuring another virtual machine to have a low amount of resources for a low-performance workload.
Better Isolation Between Virtual Machines
Finally, Type 3 hypervisors provide better isolation between virtual machines than other types of hypervisors. This is because each virtual machine is running on its own instance of the hypervisor, rather than sharing the same instance as other virtual machines. This ensures that each virtual machine is completely isolated from the others, both in terms of hardware resources and the operating system environment. This can be especially important in security-sensitive environments, where it is important to prevent one virtual machine from accessing or affecting another.
Efficient Resource Utilization
Type 3 hypervisors, also known as hosted hypervisors, are software programs that run on a host operating system and manage other virtual machines (VMs) running on the same physical machine. One of the main advantages of using Type 3 hypervisors is their ability to efficiently utilize resources.
Shared Resources
In a traditional computing environment, each physical machine is dedicated to running a single operating system and set of applications. This means that resources such as CPU, memory, and storage are used exclusively by each machine, and are not shared with other machines. However, with Type 3 hypervisors, multiple VMs can run on the same physical machine, sharing resources such as CPU, memory, and storage. This allows for more efficient use of resources, as multiple VMs can run on a single physical machine, reducing the need for additional hardware.
