Embodiment Construction

[0043] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] The invention provides a data sharing method of a virtual machine.

[0045] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the data sharing method for virtual machines in the present invention.

[0046] This embodiment proposes a data sharing method for a virtual machine, and the data sharing method for a virtual machine includes:

[0047] Step S10, the first virtual machine stores the first data to be shared in the shared memory;

[0048] In this embodiment, the application scenario is that each virtual machine in the same host performs data sharing, and when each virtual machine in the same host performs data sharing, in order to reduce operations such as data copying and forwarding, it is preferable to use memory The sharing technology realizes the transfer of control...

Abstract

The invention discloses a data sharing method of a virtual machine, which comprises the steps that a first virtual machine stores first data to be shared into a shared memory; the first virtual machine acquires storage address information of the first data to be shared and a destination physical address to be shared; the first virtual machine packages the storage address information and the destination physical address into a first packet to be shared; and the first virtual machine stores the first packet to be shared into a transmission queue corresponding to the first virtual machine. The invention further discloses a data sharing device of the virtual machine. The data sharing method and device disclosed by the invention improve the data sharing efficiency of the virtual machine.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a data sharing method and device for a virtual machine. Background technique [0002] With the rapid development of communication technology, NFV (Network Function Virtualizat-ion, network function virtualization) technology is becoming more and more mature. Network function virtualization needs to provide high-speed data forwarding functions, including data forwarding between physical network cards of servers and virtualization Data forwarding between virtual network cards between machines. [0003] The forwarding function of the virtual network in the server is generally realized by a virtual bridge, or OVS (Open Virtual Switch, virtual switch), but whether it is a virtual bridge or OVS, it runs in the kernel mode, and the virtual machine is located in the user mode. , and when communicating between virtual machines, data needs to be forwarded through a virtua...
