Method and apparatus for accessing virtual machine

Abstract

The present invention provides a method and apparatus for accessing a virtual machine. The method comprises: receiving an access request sent from external to a first port of a physical machine running the virtual machine; and according to a preset mapping relationship between a second port of the virtual machine and a first port, forwarding the access request to the first port of the virtual machine to allow the external to access the virtual machine. According to the method and the apparatus, the mapping relationship between the port of the virtual machine and the port of the physical machine is preset. Therefore, when there is remote access to the port of the physical machine, the remote access can be forwarded directly to the port of the virtual machine according to the mapping relationship. Direct access to the virtual machine by the external is implemented without the need for accessing the physical machine first. The physical machine is then performed to access the virtual machine running on the physical machine.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for accessing a virtual machine. Background technique [0002] At work, if a physical computer of a different system is configured for each employee, the cost is very high, so many organizations often use virtual machines running on physical computers as the working environment for employees. [0003] The network setting of the virtual machine usually adopts the NAT (NetworkAddressTranslation, network address translation) method. The virtual machine network card on the physical machine assigns a C-class IP address to each virtual machine, which does not occupy the real IP inside the organization. The virtual machine can serve through NAT. Connect to other machines within the organization, other machines cannot access the virtual machine, one-way connection. [0004] In the current common software development and testing environment, multiple virtual...

Problems solved by technology

This brings about the following problems: 1. The physical machine where the virtual machine is located is often a server, which cannot give remote permissions to the debugger; 2. Multiple people remotely access the physical machine, which is not easy to restrict the user's operation, which will cause damage to the physical machine system. Risk; 3. The virtual machine runs in the background on the physical machine. If you open the virtual machine (such as VMware virtual machine) through a window, because it is a visual window operation, it will increase the system load and cause the virtual machine to shut down abnormally.
