  • Publication number: 20200150997
    Abstract: Methods, software, and apparatus for implementing live migration of virtual machines hosted by a Linux operating system (OS) and running a Microsoft Windows OS. Communication between the VM and a network device is implementing using a virtual function (VF) datapath coupled to a Single-root input/output virtualization (SR-IOV) VF on the network device and an emulated interface coupled to a physical function on the network device, wherein the emulated interface employs software components in a Hypervisor, and the VF datapath bypasses the Hypervisor. In one aspect, the VF datapath is active when the SR-IOV VF is available, and the datapath fails over to the emulated data path when the SR-IOV VF is not available. Disclosed live migration solutions employ Windows NDIS (Network Driver Interface Specification) components including NDIS Miniport interfaces and MUX IM drivers, enabling live migration to be transparent to the Windows OS. NetKVM drivers are also used for Linux Hypervisors including KVM.

  • Publication number: 20190114194
    Abstract: Examples may include a method of instantiating a virtual machine; instantiating a virtual device to transmit data to and receive data from assigned resources of a shared physical device by receiving input data requesting assigned resources for the virtual device, allocating assigned resources to the virtual device based at least in part on the input data, and mapping a page location in an address space of the shared physical device for a selected one of the assigned resources to a page location in a memory-mapped input/output (MMIO) space of the virtual device; and assigning the virtual device to the virtual machine, the virtual machine to transmit data to and receive data from the physical device via the MMIO space of the virtual device.

  • Publication number: 20190114283
    Abstract: Examples may include a computing platform having a host driver to get a packet descriptor of a received packet stored in a receive queue and to modify the packet descriptor from a first format to a second format. The computing platform also includes a guest virtual machine including a guest driver coupled to the host driver, the guest driver to receive the modified packet descriptor and to read a packet buffer stored in the receive queue using the modified packet descriptor, the packet buffer corresponding to the packet descriptor.

  • Publication number: 20190107965
    Abstract: Examples may include a method of protecting memory and I/O transactions. The method includes allocating memory for an application, assigning a resource of a physical device to the application, assigning a process address space identifier to the assigned resource, creating a security enclave to protect the allocated memory of the application, and associating the security enclave with the process address space identifier to protect the allocated memory and the assigned resource.

  • Publication number: 20190108106
    Abstract: Examples include a method of performing failover of in an I/O architecture by allocating a first set of resources, associated with a first port of a physical device, to a virtual device, allocating a second set of resources, associated with a second port of the physical device, to the virtual device, assigning the virtual device to a virtual machine, activating the first set of resources, and transferring data between the virtual machine and the first port using the virtual device and the first set of resources. The method further includes detecting an error in the first set of resources, deactivating the first set of resources and activating the second set of resources, and transferring data between the virtual machine and the second port using the virtual device and the second set of resources.

  • Publication number: 20030002478
    Abstract: An Internet Protocol (IP) telephony system includes a lightweight stimulus client configured to receive user input requesting an IP telephony service (e.g., an ITU-T H.450 supplementary service) and communicate the received input over a packet-based network using a standard call control protocol (e.g., Media Gateway Control Protocol or ITU-T H.248). A call agent, executing on a remote server connected to the packet-based network, is configured to perform the requested IP telephony service based on the received input.
