Abstract: Embodiments of this application disclose a packet sending method, a device, and a system, so that a specified network device does not use a backup forwarding path to forward a packet, thereby reducing, to some extent, a technical problem such as network resource waste or network congestion caused by a loop problem. The method includes: A first network device obtains a first packet destined for a destination device; the first network device adds a first indication identifier to the first packet to generate a second packet, where the first indication identifier is used to indicate a second network device to avoid using a backup forwarding path from the second network device to the destination device to send the second packet to the destination device; and the first network device sends the second packet to the second network device by using a first forwarding path.

Abstract: This application discloses a forwarding entry generation method, a packet sending method, a network device, and a system, so that a specified network device cannot use a backup forwarding path to forward a packet, thereby reducing, to some extent, a technical problem such as network resource waste or network congestion caused by a loop problem. The method includes: A first network device obtains routing information advertised by a second network device; and the first network device determines that the routing information advertised by the second network device matches a summary route stored in the first network device, and generates, based on a segment identifier of the second network device, a forwarding entry corresponding to the summary route. The forwarding entry includes the segment identifier of the second network device, and a forwarding path corresponding to the forwarding entry passes through the second network device.

Abstract: Example virtual machine live migration methods and apparatus are described. In one example method, a first virtual machine which runs on a source server is migrated to a destination server. The source server includes a single-root input/output virtualization (SR-IOV) network adapter. The virtual machine manager delivers a live migration command to the live migration module. The live migration module obtains, according to the live migration command, information that needs to be migrated and that is about the first virtual machine, and reports the information to the virtual machine manager, where the information includes state information of the first virtual network adapter and memory data of the first virtual machine. The virtual machine manager sends the state information and the memory data of the first virtual machine to the destination server.
