VMM (Virtual Machine Monitor), also known as Hypervisor, is the software layer that manages the virtualization environment and enables multiple virtual machines to share the same physical server resources. The VMM should meet certain requirements to ensure efficient and secure virtualization. Some of the key requirements of VMM are:
Resource Allocation: The VMM must have the ability to allocate physical resources, such as CPU, memory, and storage, to virtual machines in a way that ensures optimal performance and utilization.
Isolation: The VMM should provide a secure, isolated environment for each virtual machine to prevent any unauthorized access or interference from other virtual machines.
Management and Monitoring: The VMM should have the ability to manage and monitor the virtual machines running on the physical server. This includes the ability to start, stop, and migrate virtual machines between physical servers.
Compatibility: The VMM should be compatible with the underlying hardware, operating systems, and applications running on the physical server.
Scalability: The VMM should be able to scale to support a large number of virtual machines running on a single physical server or across multiple physical servers.
Performance: The VMM should have low overhead and minimal impact on the performance of the virtual machines running on the physical server.
Security: The VMM should have built-in security features to prevent any unauthorized access or modification of the virtual machines or the virtualization environment.
Fault Tolerance: The VMM should have the ability to detect and recover from any hardware or software failures to ensure continuous availability of the virtual machines.
In summary, the VMM plays a critical role in virtualization, and it must meet specific requirements to ensure efficient and secure virtualization.
