摘要： A system and method for migration of a virtual endpoint from one virtual plane to another are provided. With the system and method, when a management application requests migration of a virtual endpoint (VE) from one virtual plane (VP) to another, a fabric manager provides an input/output virtualization intermediary (IOVI) with an interrupt to perform a stateless migration. The IOVI quiesces outstanding requests to the virtual functions (VFs) of the VE, causes a function level reset of the VFs, deconfigures addresses in intermediary switches corresponding to the VP, and informs the fabric manager that a destination migration is requested. The fabric manager sends an interrupt to the destination IOVI which performs a function level reset of the destination VFs and reprograms the intermediary switches with the addresses of the destination VP. The destination VFs may then be placed in an active state.

摘要： A system and method for migration of stateless virtual functions from one virtual plane to another are provided. When a migration of a source virtual function to a destination virtual function in another virtual plane is to be performed, a source single root PCI manager (SR-PCIM) is first interrupted by a multiple root PCI manager (MR-PCIM). Configuration information that defines the source virtual function is then redefined on the destination virtual function for this stateless migration. A function level reset may then be performed on the source virtual function. The destination SR-PCIM may be interrupted by the MR-PCIM with an interrupt for the destination virtual function. A function level reset may then be performed on the destination virtual function. The destination virtual function state may then be changed to an “active” state such that the migrated virtual function begins processing transactions.

摘要： An approach is provided in which a hardware accelerated bridge executing on a network adapter receives an ingress data packet. The data packet includes a destination MAC address that corresponds to a virtual machine, which interfaces to a software bridge executing on a hypervisor. The hardware accelerated bridge identifies a software bridge table entry that includes the destination MAC address and a virtual function identifier, which identifies a virtual function corresponding to the software bridge. In turn, the hardware accelerated bridge sends the data packet from the hardware accelerated bridge to the software bridge through the identified virtual function.

摘要： An approach is provided which a system selects a first virtual function from a plurality of virtual functions executing on a network adapter that includes a memory area. Next, the system allocates, in the memory area, a memory corresponding to the first virtual function. The system then stores one or more translation entries in the allocated memory partition, which are utilized to send data traversing through the first virtual function. As such, the system sends, utilizing one or more of the translation entries, the data packets from the network adapter to one or more destinations. In turn, the system dynamically resizes the memory partition based upon an amount of the memory partition that is utilized to store the one or more translation entries.

摘要： According to one embodiment of the present disclosure, an approach is provided in which a policy server receives a request for a policy from a requestor. The policy server identifies an initiating virtual machine; the initial virtual machine's corresponding virtual network; and a destination virtual machine. Next, a policy corresponding to sending data from the first virtual machine to the second virtual machine is selected. The policy includes one or more logical references to the virtual network and does not include a physical reference to a physical entity located on a physical network. In turn, a physical path translation corresponding to the selected policy is identified and sent to the requestor.

摘要： An approach is provided in which a discovery system receives a migration request to move a virtual machine that executes on a first system. The discovery system identifies a first network adapter corresponding to the first system, and identifies hardware state data used by the first network adapter to process data packets generated by the virtual machine. In turn, the discovery system identifies a second network adapter that is compatible with a native format of the hardware state data, and migrates the virtual machine to a second system corresponding to the identified second network adapter.

摘要： An approach is provided in which a data traffic module executing on a network interface card receives a data packet initiated by a first virtual machine with a destination at a second virtual machine. The data traffic module identifies one or more physical path translations corresponding to a logical connectivity that is independent of physical topology constraints of a physical network. In turn, the data traffic module encapsulates the data packet with the one or more physical path translations and sends the encapsulated data packet to the second virtual machine over the physical network.

摘要： An approach is provided in which a hypervisor provisions switch resources on a network interface card, which includes a virtual switch and a physical port. The hypervisor invokes a switch control module on a virtual machine, which provides control information to one or more of the switch resources. In turn, one or more of the switch resources utilize the control information to direct data packets between a source virtual machine and a destination virtual machine over one or more virtual networks that are independent of physical topology constraints of a physical network.
