    摘要： A method of managing resources in a host computer includes generating a virtual service provider in two different computer partitions and linking them in a serial manner. The virtual service providers are associated with a computer resource. Virtual service clients in different partitions may use the virtual service provider software to access the related computer resources. The virtual service providers provide a transparent interface to the associated hardware. Virtual service clients can use the combination of series computer resource functions or can access the a lesser number of the series connected virtual service providers. Fault tolerance can be built into the scheme using multiple virtual service providers located in different partitions accessible to virtual service clients using a failover control technique.

    摘要： A method of agreeing on the utilization of at least one computer resource between two virtual machines includes sending a first resource request by a first virtual machine to a second virtual machine having computer resources to allocate to the first virtual machine. The second virtual machine responds by sending at least one available resource for use by the first virtual machine. The first virtual machine can select from the at least one available resource. Both the first and second virtual machines can then execute on the agreed resource utilization by the first virtual machine and begin using the resource. When conditions change, either the first virtual machine or the second virtual machine can request a renegotiation of the agreement to use computer resources.

    摘要： A system and method for reducing the cost of framing network packets in a virtual machine environment combines certain network objects to eliminate the cost of fully framing packets between the combined objects. In a virtual environment, for example, this allows a virtual NIC in one partition to send only data to a network provider partition and to rely on the latter to frame and route the data. A source network object, destination network object, or an intermediate network object may enable a separate intermediate network object to frame its data so that the network system may take advantage of offload framing when one or more of the intermediate network object's ports has the capacity to offload framing. Alternatively, the intermediate network object may perform the offload itself. Also, the source or destination network object may query the intermediate network object for properties (such as the MTU of the network), or the intermediate network object may push its properties to the source and/or destination network objects through a back control data communications channel. The intermediate network object may further reconfigure the VM network for the purpose of efficiency by reconfiguring the network tree into a graph for increased performance for traffic moving between the nodes.

    摘要： A computer system and method for communicating in a virtual environment. The computer system may include a first partition and a virtual service client implemented at a first position in the first partition. The computer system may also include a second partition, and a virtual service provider implemented at a second position in the second partition. The first partition and the second partition may be in operative communication via the virtual service client and the virtual service provider. The first position and the second position may enable the virtual service client and the virtual service provider to reduce processing overhead associated with communicating in the virtual environment by eliminating a processing step, a buffer copy, a software interrupt, and/or a context switch.

    摘要： A system and method is provided that enables older legacy guest operating systems like Windows NT 4.0 and Windows95® to take advantage of newly developed NDIS Intermediate (IM) drivers that support firewalls, quality of service, IP security, intrusion detection, and other functionality for monitoring/filtering incoming and outgoing network traffic in contemporary host operating systems such as Windows XP operating in a virtual machine (VM) environment. The invention thus makes such older legacy operating systems less susceptible to Internet viruses, and worms, network denial of service (DOS) attacks, and the like. For each Virtual Network Interface Card (VNIC) in a guest VM, a corresponding VNIC is created on the host OS, and a point to point connection is established between the guest and host VNICs. The NDIS IM drivers bind themselves on top of the host VNIC and effectively place themselves as a filter on the point to point connection.

    摘要： A method to interact with a local USB device is disclosed. Messages are transmitted to a remote host controller driver from a host controller associated with the local USB device. Messages are received from the remote host controller driver for the host controller. In some embodiments, a transfer descriptor prototype is received from the remote host controller driver. A completed transfer descriptor is received from the remote host controller driver. The completed transfer descriptor and the transfer descriptor prototype are transformed into a modified transfer descriptor in part by using a collection of rules. The modified transfer descriptor is submitted to the local host controller without intervention from the remote host controller driver.

    摘要： An algorithm for dynamically adjusting the number of processors servicing Virtual Machine Queues (VMQ) and the mapping of the VMQ to the processors based on network load and processor usage in the system The algorithm determines the total load on a processor and depending on whether the total load exceeds or falls below a threshold respectively, the algorithm moves at least one of the VMQs to a different processor based on certain criteria such as whether the destination processor is the home processor to the VMQ or whether it shares a common NUMA node with the VMQ. By doing so, better I/O throughput and lower power consumption can be achieved.
