Among various virtualization platforms, such as VMWare, openStack, VSphere platform, deep belief super fusion platform, etc., the information of the KVM virtual machine is generally obtained by installing a proxy tool in the KVM virtual machine.
KVM (Kernel-based Virtual Machine for short) is an open-source system virtualization module, which is integrated in each main release of Linux after Linux 2.6.20. It uses the Linux's own scheduler for management, so its core source code is very small compared to Xen. KVM has become one of the mainstream VMMs in the academic world, and is widely used in computer virtualization applications. Socket is a convention or a manner of communication between computers, through which a computer may receive data from or send data to other computers, and is an abstraction layer through which an application may send or receive data, and which allows an application to insert I/O into a network and communicate with other applications in the network.
In the existing cloud platform, the method for obtaining the IP address of the virtual machine generally comprises the steps of installing a proxy tool in the virtual machine, enabling a computing node to obtain information of the virtual machine through the proxy tool, and enabling a management platform to obtain the IP address of the virtual machine by calling related services provided by the cloud platform. However, in the Linux native virtualization KVM system, there is no corresponding agent, so the management platform cannot obtain the address of the KVM virtual machine.
Therefore, in order to solve the above problems, the present invention is urgently needed to provide a method for quickly obtaining the KVM virtual machine address based on Socket technology.
