Embodiment 1

[0046] like figure 1 As shown, this embodiment provides a virtual machine migration control method, which can be applied to a virtual machine creation system including devices such as SDN controllers, VTEPs, VMs, and cloud management platforms.

[0047] In the virtual machine migration method provided in this embodiment, the SDN controller is used to establish a TCP connection with the cloud management platform, and information related to virtual machine generation and migration is sent to ensure that the virtual machine is smoothly carried out between physical hosts under the same VTEP or different VTEPs. migrate.

[0048] In this embodiment, the cloud management platform can realize docking with the SDN controller through the TCP (Transmission Control Protocol) protocol, and select an undefined port as the port for transmitting TCP data packets with the cloud management platform. And keep connected with the cloud management platform through heartbeat information.

[0049] ...

Embodiment 2

[0061] like figure 2 As shown, the embodiment of the present invention provides a virtual machine migration control method. When applied to an SDN controller, optionally, after the cloud management platform creates a VM for the first time, it also includes: receiving information about the virtual machine sent by the VTEP where the virtual machine is located Gratuitous ARP request: Generate the ARP entry of the virtual machine according to the gratuitous ARP request, and send the ARP entry to all VTEPs.

[0062] When applied to an SDN controller, the virtual machine migration control method may specifically include the following steps:

[0063] S21. Receive the migration information of the virtual machine sent by the cloud management platform.

[0064] Wherein, the content of the virtual machine migration information includes the virtual machine IP address, MAC address, VLAN, and the migrated VTEP.

[0065] S22. Determine the VTEP where the virtual machine is located after m...

Embodiment 3

[0098] like image 3 As shown, the embodiment of the present invention also provides a cloud management platform, which can control the migration of a virtual machine according to the virtual machine migration control method provided in Embodiment 1. The cloud management platform includes: a receiving unit, a migration unit and a sending unit. in,

[0099] The receiving unit is used for receiving the migration request of the virtual machine.

[0100] The migration unit is used to select a physical host for the virtual machine according to preset conditions according to the migration request, and migrate the virtual machine to the physical host.

[0101] The sending unit is used to send the migration information of the virtual machine to the SDN controller.

[0102] Optionally, the migration unit includes: a judging module, configured to judge whether there is a physical host satisfying the migration condition of the virtual machine in the VTEP where the virtual machine is c...

Abstract

The invention provides a virtual machine migration control method, a cloud management platform and an SDN (Software Defined Network) manager, belongs to the technical field of extensible virtual local area networks, and can at least partially solve the problem of migration failure of an existing virtual machine migration mode during network congestion. The virtual machine migration control method comprises the following steps: receiving a migration request of a virtual machine; according to the migration request, selecting a physical host for the virtual machine according to a preset condition, and migrating the virtual machine to the physical host; and sending the migration information of the virtual machine to an SDN controller.

Description

technical field [0001] The invention belongs to the technical field of scalable virtual local area network, and in particular relates to a virtual machine migration control method, a cloud management platform, and an SDN manager. Background technique [0002] In a VXLAN (Virtual eXtensible LAN, scalable virtual local area network) network, when a VM (Virtual Machine, virtual machine) migrates from a VTEP (VXLAN Tunnel End Point, VXLAN Tunnel End Point) to another VTEP, the VTEP to which it belongs after the migration will correspond to The EVPN routing information carrying the migration extended community attribute value of the VM is synchronized to other VETEPs in the VXLAN; among them, the migration extended community attribute value is the number value, and each time a VM migrates, the VTEP maintenance number increases by 1. After receiving the EVPN routing information, other VTEPs compare the number value in the EVPN routing information with the number value maintained b...
