摘要： A method comprises determining a flexible limit on an amount of resource usage by a driver domain on behalf of a given virtual machine (VM). The method further comprises controlling the resource usage by the driver domain on behalf of the given VM so as not to exceed the flexible limit except under a permitted condition. In certain embodiments the resource usage by the driver domain on behalf of the given VM is controlled so as not to exceed the flexible limit except when a slack share of resource usage is available to the driver domain. Such a slack share of resource usage is a share of resource usage allocated to the driver domain that will not otherwise be used on behalf of another VM.

摘要： A method comprises scheduling, by a weighted proportional-share virtual time processor scheduler, processor access to a first consumer during a time period in which a second consumer is blocked from processor access. When the second consumer becomes unblocked from processor access, the weighted proportional-share virtual time processor scheduler determines whether the length of the time period over which the second consumer was blocked from processor access exceeds a predefined time threshold. When determined that the length of the time period over which the second consumer was blocked from processor access does not exceed the predefined time threshold, then scheduler does not update the virtual time of the second consumer before scheduling processor access for the second consumer.

摘要： A method comprises observing communication through a virtualized interface between at least one virtual machine (VM) and a driver domain. Based on the observed communication through the virtualized interface, a weighted amount of communication between the VM and the driver domain is determined for each of the VM(s), wherein the weighted amount is based at least in part on at least one characteristic of the observed communication, such as directional flow and/or size of packets in the communication. Another method comprises evaluating CPU utilization of a target network driver domain in processing communications having different characteristics, and deriving corresponding weighting for the different communication characteristics. The derived weighting for the different communication characteristics are employed within a communication monitor that observes communication between virtual machines and the target network driver domain.
