Embodiment 1
[0015] Embodiment 1, the network connection method of the remote VM in the desktop cloud of this embodiment, see figure 1 shown, including the following main steps:
[0016] S11. Create a corresponding network bridge when the server starts; and create a corresponding network bridge when the remote virtual machine starts up the terminal.
[0017] In the specific implementation of this step, the switch connected by the terminal and the switch connected by the server are isolated from each other, which can be separated by VLAN, or connected to different switches.
[0018] When the server starts and the terminal starts, it is necessary to use OpenVswitch to create the br0 bridge, for example, it can be realized by using the "#ovs-vsctl add-br br0" statement. After the remote VM is started in the terminal, a Linux virtual network card tap0 will be generated, and the tap0 network card will be added to an OpenVswitch bridge br0 to forward the packets of the VM.
[0019] S12. The se...
Embodiment 2
[0034] Embodiment 2, the network connection system of the remote virtual machine in the desktop cloud in this embodiment is established based on the network connection method for the remote VM in the desktop cloud in the above-mentioned embodiment 1, see figure 2 As shown, it includes: a server 21, the server 21 is connected to the router 23 through the first switch 22; a terminal 24, the terminal 24 is connected to the router 23 through the second switch 25; the router 23 is also connected to the network firewall 26. Wherein, a VXLAN tunnel 27 is established between the server 21 and the terminal 24 to connect.
[0035]Wherein, the server 21 includes: a desktop cloud web management platform 211, a physical network card 212 and a network bridge 213, and there may be more than one physical network card 212, represented by eth01, eth02, etc., and the physical network card 212 needs to be added to the network bridge 213.
[0036] The terminal 24 includes: a remote virtual machin...

Abstract
The invention provides a network connection method and system of a far-end virtual machine in desktop cloud, and relates to the field of a computer and a network. The method and the system are used for solving the problem of how to bring network resources back to a server. The method comprises following steps of establishing a corresponding network bridge when the server is started; establishing the corresponding network bridge by the far-end virtual machine when the terminal is started; obtaining the IP (Internet Protocol) address of the terminal and establishing a VXLAN (virtual Extensible LAN) tunnel with the terminal by the server; obtaining the IP address of the server and establishing the VXLAN tunnel with the server by the terminal; obtaining the starting parameters of the virtual machine by the terminal; and configuring the starting parameters on the network bridge established by the terminal. The system comprises the server which is connected with a router by a first switch; the terminal which is connected with the router through a second switch; the router which is also connected with a network firewall; and the VXLAN tunnel connection which is established between the server and the terminal.
Description
【Technical field】 [0001] The invention relates to the field of computers and networks, in particular to a network connection method and system for a remote virtual machine in a desktop cloud. 【Background technique】 [0002] Desktop cloud is a relatively hot emerging technology in China in recent years, and it is a branch of the virtualization field. There are many desktop cloud products in the domestic market. The basic structure of the desktop cloud is to run a VM (Virtual Machine, virtual machine) on the server, and cooperate with the web management platform for unified management. The computing resources, storage resources, and network resources of the VM are all integrated on the server. With the development of desktop cloud technology, the solution of running VMs on servers has gradually revealed some problems. The biggest problem is that the number of running VMs is limited, so a compromise solution has been created. [0003] Another existing desktop cloud architect...
