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; 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 virtual device.

Virtual device composition in a scalable input/output (I/O) virtualization (S-IOV) architecture

Techniques for providing adaptive virtual function (VF) drivers capable of operating with physical devices having a plurality of different hardware configurations are described. In one embodiment, for example, an apparatus may include logic to implement a virtual machine (VM), the logic to initialize an adaptive virtual function (VF) driver to facilitate communication between the VM and a physical device to be virtualized, establish communication between the adaptive VF driver and a physical function (PF) driver of the hypervisor for the physical device, activate a standard feature set for the adaptive VF driver to execute on a PF of the physical device, and negotiate activation of an advanced feature set for the adaptive VF driver to execute on the PF, the adaptive VF driver to provide the advanced feature set to the PF, the PF activate each feature of the advanced feature set supported by the PF.

Adaptive virtual function drivers for electronic devices

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.

Zero copy host interface in a scalable input/output (I/O) virtualization (S-IOV) architecture

Examples include a method of live migrating a virtual device by creating a virtual device in a virtual machine, creating first and second interfaces for the virtual device, transferring data over the first interface, detecting a disconnection of the virtual device from the virtual machine, switching data transfers for the virtual device from the first interface to the second interface, detecting a reconnection of the virtual device to the virtual machine, and switching data transfers for the virtual device from the second interface to the first interface.

Live migration of virtual devices in a scalable input/output (I/O) virtualization (S-IOV) architecture

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.

Memory enclaves using process address space identifiers in a scalable input/output (I/O) virtualization (S-IOV) architecture

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.

Flexible memory mapped input/output (I/O) space definition for a virtual device in a scalable I/O virtualization (S-IOV) architecture

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.

Failover of virtual devices in a scalable input/output (I/O) virtualization (S-IOV) architecture

A method and system for filtering data packets in a multiple-call environment are described. In one embodiment, each data packet received from a packet source is associated with an identifier of an IP telephone call that corresponds to this data packet. The IP telephone call is identified using information contained in the data packet. In one embodiment, all data packets related to a specific IP telephone call can be traced using the identifier of the specific IP telephone call.
