Summary of the invention
In order to solve the above technical problems, the invention proposes improve network data transmission rate under a kind of virtual environment
Method.
The method of network data transmission rate is improved under a kind of virtual environment of the invention.By establishing internal data transfer
Channel and optimization virtual machine software and hardware configuration parameter, promote virtual machine overall performance, greatly improve virtual machine and external environment
Carry out the message transmission rate of network communication.
Virtual platform technical characteristic is sufficiently used, establishes the internal data transfer channel of virtual machine and host, and with
Host is combined with the physical network channel of external equipment, uses virtual network and external equipment network interconnection instead of virtual machine
Mode, promoted virtual machine and external equipment network data transmission efficiency.
According to the configuration of host physical platform and practical application scene, the virtualization of integrated use hardware auxiliary, virtual money
The virtualization technologies such as source distribution, task process priority scheduling strategy, to the hardware devices such as virtual cpu, memory, network interface with
And operating system optimizes configuration, promotes virtual machine overall performance, provides good running environment for virtual machine network transmission.
Construct the data transmission path of virtual machine and host
Firstly, establishing the network connection of virtual equipment and external equipment with gigabit networking, then established altogether on external equipment
File is enjoyed, and establishes the network drive of external equipment Shared Folders on virtual equipment host；
Then, in the virtual platform of virtual equipment, " virtual machine " menu → " setting " menu is selected, in " option " page
In, it selects " Shared Folders ", chooses " enabling always in shutdown next time or before hanging up " and " be mapped as network in a client to drive
Dynamic device " option, clicks " addition ... " button, and the mapped network drive established on selection host in " host paths " is built
The data transmission path of vertical virtual machine and host realizes that virtual machine can be carried out by this data transmission channel and host
Data transmission；
Optimization promotes virtual machine overall performance
It is mentioned using technologies such as the virtualization of hardware auxiliary, optimization virtual resource allocation, optimization task process priority scheduling strategies
Rise virtual machine performance；
（1）Open hardware auxiliary virtualization
By taking X86 physics machine platform as an example, in virtual platform, virtual machine → setting → hardware → processor → virtualization is drawn
It holds up, preferred mode selects " automatic ", chooses " virtualization Intel VT-x/EPT or AMD-V/RVI（V）" option；
（2）Optimize virtual resource allocation
CPU and memory virtual resource allocation basic principle are as follows：
C) the total core amounts distributed to virtual machine do not exceed the half of total core amounts of physical machine；
D) memory size distributed to virtual machine, does not exceed the half of physical machine memory；
（3）Optimize task process priority scheduling strategy
In virtual platform, virtual machine → setting → option → advanced → process priority, " input content of crawl " is set as
Height, " input content for cancelling crawl " are set as normal；
（4）Optimize virtual machine network configuration
D) virtual machine → setting → hardware → network adapter, two virtual network ports are changed to be directly connected to physical network in virtual machine
Bridge mode；
E) in virtual machine control panel, the IP address of two virtual network ports is set as distributing automatically；
F) in physical machine network connection, the IP of the IP address of the VMnet1 and VMnet8 of virtual machine and locally-attached two network interfaces
It address will be in different network segments.
By above method, additional capital investment is not needed to promote hardware configuration, only needs integrated use internal data
Passage technology and a variety of virtualization optimisation techniques, can be obviously improved the network data transmission rate of virtual machine, reach
Or the network transmission performance close to physical machine, meet the application demand of big data quantity network data transmission.
Detailed description of the invention
Fig. 1 is for typical virtualized environment lower network data transmission applications system architecture diagram.
Specific embodiment
More detailed elaboration is carried out to the contents of the present invention below：
To establish virtual machine on VMware virtual platform, said for being carried out data transmission by gigabit networking with external equipment
Bright specific operation process.
Step 1：Construct the data transmission path of virtual machine and host
Firstly, the network connection of virtual equipment and external equipment is established with gigabit networking according to attached drawing 1, then in external equipment
On establish Shared Folders, and the network drive of external equipment Shared Folders is established on virtual equipment host.
Then, in the virtual platform of virtual equipment, " virtual machine " menu → " setting " menu is selected, at " option "
It in the page, selects " Shared Folders ", choose " enabling always in shutdown next time or before hanging up " and " is mapped as net in a client
Network driver " option clicks " addition ... " button, the mapping network driving established on selection host in " host paths "
Device establishes the data transmission path of virtual machine and host, realizes that virtual machine can pass through this data transmission channel and host
Machine carries out data transmission.
Step 2：Optimization promotes virtual machine overall performance
It is mentioned using technologies such as the virtualization of hardware auxiliary, optimization virtual resource allocation, optimization task process priority scheduling strategies
Rise virtual machine performance.
（1）Open hardware auxiliary virtualization
