A Type 2 hypervisor differs from a Type 1 hypervisor in that it runs on top of another operating system rather than directly tied into the underlying hardware of the virtual host servers.

With this type of implementation, additional security and architecture concerns come into play because the interaction between the operating system and the hypervisor becomes a critical link.

The hypervisor no longer has direct interaction and control over the underlying hardware, which means that some performance will be lost due to the operating system in the middle needing its own resources, patching requirements, and operational oversight.

A hypervisor is a virtualization layer that allows multiple operating systems to run on a single physical machine. There are two types of hypervisors, namely Type 1 and Type 2. A Type 1 hypervisor runs directly on the host machine's hardware and provides virtualization capabilities to the guest operating systems. In contrast, a Type 2 hypervisor runs as an application within a host operating system and provides virtualization capabilities to the guest operating systems.

When it comes to security control, a Type 1 hypervisor is generally considered more secure than a Type 2 hypervisor. This is because a Type 1 hypervisor runs directly on the host machine's hardware and has direct access to the physical resources. Therefore, it can control and monitor the guest operating systems' activities more effectively. Additionally, the Type 1 hypervisor is not dependent on the security of the host operating system since it runs directly on the hardware.

On the other hand, a Type 2 hypervisor runs as an application within a host operating system, and it relies on the host operating system's security for its own security. This means that any security vulnerabilities in the host operating system can also affect the Type 2 hypervisor's security. Furthermore, a Type 2 hypervisor allows users to directly perform some functions with their own access, which could potentially compromise the security of the hypervisor.

In summary, a Type 1 hypervisor offers more security control because it runs directly on the host machine's hardware and is not dependent on the host operating system's security. In contrast, a Type 2 hypervisor runs as an application within a host operating system and is dependent on the host operating system's security.
