Embodiment Construction
[0016] Please refer to figure 1 , the virtualization architecture of the server is to introduce a virtualization layer on the physical server, which is a middle layer virtualization software, which is mainly used to create a virtual machine (Virtual Machine, VM) and allocate reasonable hardware resources for the virtual machine, such as One or more cores in the CPU (that is, one or more complete computing engines integrated in the CPU) are allocated to the virtual machine 1 and so on. In terms of logical function, a virtual machine is no different from a traditional physical server. It has its own operating system and can install various applications on the operating system. After the physical servers in the data center are widely virtualized, security problems also arise accordingly. In computer network and software technology, any new function may have security issues and needs to be considered. Virtualization software is equivalent to introducing new security threats base...

The invention provides a virtual machine exchange visit safety control method and a device. The method comprises that A, a double-layer message sent by a virtual machine is filtered according to preset filtration principle, if the double-layer message is conformed to the filtration principle, then the double-layer message is processed according to C; B, the double-layer message is transmitted according to a purpose media access control (MAC) address of the double-layer message; C, tunnel connection with an external network device which takes charge of safety processing is built, the received double-layer message is tunnel-sealed so as to form a tunnel message, and the tunnel message is sent to the external network device which takes charge of the safety processing through the tunnel connection; and D, the tunnel message sent by the external network device is received and unpacked so as to obtain the double-layer message after safe processing, and then the double-layer message after the safe processing is transmitted according to B. According to the virtual machine exchange visit safety control method and the device, the problem that achievement cost is high due to modification of the external network device is solved, and improvement of a server is easy.
Description
technical field [0001] The invention relates to virtualization technology, in particular to a method and device for controlling security of virtual machine mutual access. Background technique [0002] A data center typically consists of three main components: computing, networking, and storage; all three are moving toward virtualization. Among them, the virtualization of servers as computing resources is one of the core technologies in cloud computing, and it is also the most mature virtualization technology at present. Due to the mismatch of server performance and network communication ports in traditional servers, server computing performance may be idle. The server virtualization technology can virtualize a single physical server into multiple virtual machines and install their own operating systems and applications independently, thereby effectively improving the utilization efficiency of the server's own hardware resources. Contents of the invention [0003] In view...
