Problems solved by technology

However, since the current network equipment cannot perceive the migration of the virtual machine, after the virtual machine is migrated, the security policy corresponding to the virtual machine can only be migrated to the new network equipment or the new network by the network administrator manually or through the network management software. port
The above operation method is not only inefficient, but also extremely inconvenient to operate. Therefore, how to identify the migration of virtual machines on network devices has become the primary problem to be solved in the current server virtualization technology.

Embodiment 1

[0026] figure 1 It is a flow chart of a virtual machine management method provided in Embodiment 1 of the present invention. The execution subject of this embodiment is a network device, such as figure 1 As shown, the method of this embodiment includes:

[0027] Step 101, the network device receives the data packet, and parses the data packet to obtain a Media Access Control (Media Access Control; MAC for short) address in the data packet;

[0028] In this embodiment, the network device is connected to the server, and the server communicates with the outside world through the network device.

[0029] Step 102, the network device identifies whether the object to send the data packet is a virtual machine according to the MAC address and the pre-stored virtual machine MAC address.

[0030] Wherein, each virtual machine corresponds to a virtual machine MAC address, and in each embodiment of the present invention, the MAC address corresponding to the virtual machine is called a ...

Embodiment 2

[0037] figure 2 It is a flow chart of the virtual machine management method provided by Embodiment 2 of the present invention. This embodiment can be realized based on Embodiment 1, such as figure 2 As shown, the virtual machine management method in this embodiment includes:

[0038] Step 201, the network device receives the data message, and parses the data message to obtain the MAC address in the data message; that is, the network device learns the MAC address.

[0039] Step 202, the network device matches the learned MAC address with the pre-stored virtual machine MAC address, and judges whether a virtual machine MAC address that is consistent with the learned MAC address is matched; when the judgment result is yes, it indicates the match If the MAC address of the virtual machine consistent with the learned MAC address is found, that is, it is recognized that the object sending the data message is a virtual machine, then proceed to step 203; otherwise, it means that no ...

Embodiment 3

[0049] Figure 3A It is a flow chart of the virtual machine management method provided by Embodiment 3 of the present invention. This embodiment can be realized based on Embodiment 1 and Embodiment 2, such as Figure 3A As shown, the management method of this embodiment includes:

[0050] Step 301, the network device receives the data message, and parses the data message to obtain the MAC address in the data message; that is, the network device learns the MAC address.

[0051] Step 302, the network device matches the learned MAC address with the pre-stored virtual machine MAC address, and judges whether a virtual machine MAC address consistent with the learned MAC address is matched; when the judgment result is yes, execute the step 303; otherwise, execute step 305.

[0052] Step 303, the network device judges whether the virtual machine corresponding to the learned MAC address is migrated according to the learned MAC address and the pre-acquired virtual machine state table...

Abstract

The invention provides virtual machine management method and device and network equipment. The method comprises the following steps of: receiving and analyzing a data message by the network equipment to acquire an MAC (Media Access Control) address in the data message; and recognizing whether an object sending the data message is a virtual machine by the network equipment according to the MAC address and a prestored MAC address of the virtual machine. The technical scheme of the invention can be adopted to recognize the virtual machine, further manage the virtual machine, such as configuration of a security policy, and the like and overcome the defects of virtual machine recognition incapability by the network equipment in the prior art, and is beneficial to wholly improving the management efficiency of the network equipment to the virtual machine.

Description

technical field [0001] The present invention relates to network communication technology, in particular to a virtual machine management method, device and network equipment. Background technique [0002] Server virtualization is a technology that enables multiple virtual servers (also known as virtual machines in the industry) to run on a single physical server. The physical server provides abstraction of hardware resources that support the operation of multiple virtual machines, such as virtual basic input Output system (Basic Input Output System; referred to as: BIOS), virtual processors, virtual memory and virtual devices and input and output (Input Output; referred to as: IO), etc., and also provide good isolation and security for each virtual machine sex. For example: before using server virtualization technology, customer relationship management (Customer Relationship Management; referred to as: CRM) system, online games and enterprise resource planning (Enterprise Re...
