Description: The migration policy in virtualization environments refers to the rules and guidelines that determine how and when virtual machines (VMs) are moved between different hosts. This policy is fundamental for optimizing resource usage, ensuring service availability, and improving overall system performance. Migration policies can be configured to execute automatically or manually, depending on the needs of the system administrator. For example, criteria can be established based on CPU load, available memory, or the health status of the host. Additionally, these policies allow for live migrations, meaning that virtual machines can be moved without needing to shut them down, thus minimizing downtime. Implementing effective migration policies is crucial in enterprise environments where service continuity and operational efficiency are priorities. In summary, the migration policy in virtualization environments is an essential tool for the dynamic management of resources, allowing administrators to optimize the performance and availability of virtual machines.
