What is a common requirement to prevent issues with virtual machines on hosts?

Choosing the correct hypervisor type is a fundamental requirement for ensuring the effective management and operation of virtual machines on hosts. Hypervisors are the software layer that allows multiple virtual machines to run on a single physical server, and the type of hypervisor—either Type 1 (bare-metal) or Type 2 (hosted)—can significantly impact performance, resource allocation, and overall system efficiency.

Type 1 hypervisors run directly on the hardware and are often preferred for server environments due to their performance advantages. They provide better virtualization capabilities and direct access to physical resources, which is critical when running multiple virtual machines that require stable and efficient operation. On the other hand, Type 2 hypervisors run on top of an existing operating system and may introduce overhead that can hinder performance, which could lead to issues when managing multiple virtual machines.

While the other options are important for the overall functionality of a virtualized environment—like ensuring network connectivity for communication among resources, maintaining the health of physical servers to support the virtualization layer, and setting up adequate disk space for virtual machines—they don't directly address the foundational aspect of how virtualization is established and managed. The effectiveness of virtualization relies heavily on the choice of the hypervisor, making it a critical element in
