DYNAMIC HOST PERFORMANCE TUNING OF A NETWORK STACK

摘要

A tuning engine for a virtualized computing system is described that periodically collect performance metrics from the virtualized computing system, and detects whether a change in system state has occurred based on the collected metrics. The tuning engine may determine whether the virtualized computing system is densely virtualized, and accordingly modify operations and configuration settings of various components in charge of handling networking for the virtualized computing system.

1. A method comprising:
receiving performance metrics associated with at least one virtual machine (VM) executing on a host; determining that the host is in a densely provisioned state based on a comparison of at least one performance metric to a corresponding threshold; modifying scheduling of at least one process thread configured to handle emulating networking for the VM responsive to determining that the host is in the densely provisioned state; and modifying configurations of a physical network interface underlying a virtual network interface card of the VM that the host is in the densely provisioned state.
