Accompanying drawing explanation
Fig. 1 is the method flow diagram that the present invention proposes；
Fig. 2 is the system construction drawing that the present invention proposes.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical side in the embodiment of the present invention
Case is clearly and completely described.
Embodiment 1:
The present invention proposes a kind of virtual network implementation method based on Linux Bridge, described side
The flow chart of method is as it is shown in figure 1, described method includes:
S1:Linux Bridge connects physical network card, and the first physical network card on different main frames passes through
Physical switches composition data network；The second physical network card on described different main frame is handed over by physics
Connection network control unit composition of changing planes manages net；Described data network and management net collectively form void
Intend network；
S2: when there being virtual machine to join described virtual network in main frame, described network controls single
Unit sends bind command to described main frame, and described main frame will be stated virtual machine and be connected to described Linux
On Bridge；
When establishing a virtual machine in main frame, user needs this virtual machine is joined described void
Intend network, then network control unit sends bind command, described company by management net to this main frame
Connecing order is to be connected with the Linux Bridge in main frame by this virtual machine, and this main frame receives this company
After connecing order, be connected with Linux Bridge by this virtual machine, then this virtual machine has joined this void
Intend in network.
S3: when the virtual machine having connection in main frame leaves described virtual network, described network control
Unit processed sends ON-and OFF-command to described main frame, and described main frame is by the virtual machine of described connection and institute
State Linux Bridge to disconnect.
When the virtual machine of connection a certain in main frame will leave this virtual network, then network controls single
Unit sends ON-and OFF-command by management net to this main frame, described ON-and OFF-command be by this virtual machine and
Linux Bridge in main frame disconnects, when main frame receives this ON-and OFF-command, by this virtual machine with
Linux Bridge disconnects, thus this virtual machine leaves this virtual network.
Each main frame at least includes a virtual machine, and Linux Bridge described in each main frame
At least it is connected with a virtual machine in described main frame, and described in corresponding described data network
One physical network card, described second physical network card in described management net not with Linux Bridge phase
Even.
Pass through said method, it is achieved that dynamically control the connection between virtual machine and virtual network.
Embodiment 2:
The invention allows for a kind of virtual network based on Linux Bridge and realize system, this is
System structure chart is as in figure 2 it is shown, described system includes data network and management net；
Described data network, by the first physical switches, is connected with described first physical switches
The first physical network card on different main frames and the Linux being connected with described first physical network card
Bridge forms；
Described management net, is connected with described second physical switches by the second physical switches
The second physical network card and the network being connected with described second physical switches on different main frames control
Unit forms；
Described network control unit is for when there being virtual machine add or leave virtual network in main frame
Time, send to described main frame and connect or ON-and OFF-command.
Each main frame at least includes a virtual machine.
Linux Bridge described in each main frame at least with a virtual machine phase in described main frame
Connect, and described first physical network card in corresponding described data network.
Described second physical network card in described management net is not connected with Linux Bridge.
As in figure 2 it is shown, it is equal to will be added to the virtual machine in virtual network in host A and host B
Being connected with the Linux Bridge in main frame, Linux Bridge and the first physical network card connect.As:
If host A establishes a virtual machine a, and need this virtual machine a is joined host A
The virtual network at place, then network control unit sends bind command, host A root to host A
According to this bind command, virtual machine a and Linux Bridge is connected；If the virtual machine in host A 1
Will leave the virtual network at host A place, then network control unit sends to host A and disconnects
Order, virtual machine 1 is disconnected with Linux Bridge by host A according to this ON-and OFF-command.
By said system, this virtual network, departing from physical network device, decreases network pipe
The configuration amount of reason person.
Embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, relevant
The those of ordinary skill of technical field, without departing from the spirit and scope of the present invention,
Can also make a variety of changes and modification, the technical scheme of the most all equivalents falls within the present invention
Category, the scope of patent protection of the present invention should be defined by the claims.
