The embodiment of the invention relates to a migration method of a virtual machine, a switch, network management equipment and a network system. The switch in the network system is used for acquiring the communication rate of all virtue machines of a server, calculating the port rate of virtual machine ports, determining the to-be-migrated virtual machine on the virtual machine ports when the port rate achieves to the preset threshold value, and sending a migration request to the network management equipment; the network management equipment is used for inquiring a virtual machine port information table after receiving the migration request, determining a target virtual machine port, and sending a migration command to a virtual machine management server, wherein the migration command is used for enabling the virtual machine management server to execute the migration operation according to the migration command so as to obtain a migration result; and the migration result sent by the virtual machine management server is received and sent to the switch. According to the invention, when the switch monitors network congestion, the virtual machine can be migrated.
Description
technical field [0001] The invention relates to the technical field of communications, and in particular to a virtual machine migration method, a switch, a network management device and a network system. Background technique [0002] A virtual machine (Virtual Machine, VM) refers to a complete computer system that is simulated by software and has complete hardware system functions and runs in a completely isolated environment. Virtual machine migration technology provides a convenient method for server virtualization. Servers running virtual machines have a unified "virtual hardware resource", unlike traditional servers that have many different hardware resources. [0003] figure 1 It is a structural diagram of a network system in the prior art. As shown in the figure, the network system includes a server 11 where the virtual machine is located, a network device 12 and a virtual machine management server 13 . Wherein, the network device 12 is connected to the server 11 an...
