摘要： Techniques for efficient and secure implementation of network policies in a network interface controller (NIC) in a host computing device operating a virtualized computing environment. In some embodiments, the NIC may process and forward packets directly to their destinations, bypassing a parent partition of the host computing device. In particular, in some embodiments, the NIC may store network policy information to process and forward packets directly to a virtual machine (VM). If the NIC is unable to process a packet, then the NIC may forward the packet to the parent partition. In some embodiments, the NIC may use an encapsulation protocol to transmit address information in packet headers. In some embodiments, this address information may be communicated by the MC to the parent partition via a secure channel. The NIC may also obtain, and decrypt, encrypted addresses from the VMs for routing packets, bypassing the parent partition.

摘要： A system and method for relocating a subnet to a remote location includes a tether router coupled to an anchor router via a link. The tether router is coupled to a plurality of nodes, each node corresponding to a network address of a plurality of network addresses allocated to a user. The plurality of network addresses is allocated to the user by a lease broker. The link may include a private tunnel for traversing a mechanism that otherwise hinders communication from the tether router to the anchor router, such as a network address translation (NAT) mechanism.

摘要： A distributed routing domain is disclosed wherein each user or tenant can deploy a multi-subnet routing topology in a network-virtualized datacenter. A virtualization module implements the distributed routing domain and enforces a multi-subnet routing topology in a distributed fashion without requiring a standalone physical router or VM router. The topology and the routing rules are distributed in a network virtualization module on each hypervisor host, and collectively realize the multi-subnet topology for a virtual network over any physical network topology.

摘要： Methods and apparatus are provided for controlling live migration of a virtual machine from a first host to a second host in a data center. A virtual machine manager may distribute to at least one host in a virtual network an updated mapping policy that maps a customer address of the virtual machine to a provider address of the migrated virtual machine. The updated mapping policy enables hosts in the virtual network to communicate with the migrated virtual machine. The updated mapping policy can be a shadow policy. The shadow policy is transmitted to hosts in the virtual network by the virtual machine manager before live migration of the virtual machine completes and is maintained by recipient hosts in an inactive state until triggered. The virtual machine manager notifies hosts in the virtual network to activate the shadow policy when live migration completes.

摘要： Methods and apparatus are provided for controlling communication between a virtualized network and non-virtualized entities using a virtualization gateway. A packet is sent by a virtual machine in the virtualized network to a non-virtualized entity. The packet is routed by the host of the virtual machine to a provider address of the virtualization gateway. The gateway translates the provider address of the gateway to a destination address of the non-virtualized entity and sends the packet to the non-virtualized entity. The non-virtualized entity may be a physical resource, such as a physical server or a storage device. The physical resource may be dedicated to one customer or may be shared among customers.
