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.

A method comprises determining an amount to which resource usage by a driver domain on behalf of a given virtual machine (VM) is to be limited. The method further comprises controlling the resource usage by the driver domain on behalf of the given VM so as not to exceed the determined amount. A system comprises a VM, a driver domain, and a shared resource that is usable by the VM and by the driver domain. The system further comprises a controller for limiting usage of the shared resource by the driver domain on behalf of the VM to prevent the usage of the shared resource by the driver domain on behalf of the VM from exceeding a determined amount.

A system for managing resources automatically among nodes includes a node controller configured to dynamically manage allocation of node resources to individual workloads, where each of the nodes is contained in one of a plurality of pods. The system also includes a pod controller configured to manage live migration of workloads between nodes within one of the plurality of pods, where the plurality of pods are contained in a pod set. The system further includes a pod set controller configured to manage capacity planning for the pods contained in the pod set. The node controller, the pod controller and the pod set controller are interfaced with each other to enable the controllers to meet common service policies in an automated manner. The node controller, the pod controller and the pod set controller are also interfaced with a common user interface to receive service policy information.

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.

According to at least one embodiment, a method comprises observing communication from a virtual machine (VM) to a domain in which a device driver for a shared resource resides. The method further comprises determining, based on the observed communication, CPU utilization of the domain that is attributable to the VM. According to at least one embodiment, a system comprises a Central Processing Unit (CPU), Virtual Machines (VMs), and a domain in which a device driver for a shared resource resides, wherein the domain is operable to receive requests from the VMs for access to the shared resource. The system further comprises a CPU utilization monitor operable to determine an amount of CPU utilization of the domain in processing the received requests that is attributable to each of the VMs.
