Change Microsoft Loopback Adapter configuration information provided in an embodiment of the present invention is introduced below by several examples
Method.
Example 1：The scene of the MAC Address of first Microsoft Loopback Adapter need to be set for the first sub-operating system.
Fig. 3 is referred to, an electronic equipment passes through two physical network cards and Ethernet switch (Ethernet
Switch) connect.A virtual machine (being for example referred to as VM 110), VM 110 have been run in the electronic equipment
It is connected by OVS with master operating system, configuring request can be interacted by the form of ether network packet.
Two pieces of physical network cards of the electronic equipment are respectively designated as NIC1 100 and NIC2 102, wherein NIC1 100
VF ports are configured by SR-IOV, such as NIC1 100 VF is VF1 104, and NIC2 102 is same
VF ports are configured by SR-IOV, such as NIC2 102 VF is VF2 106.By 104 points of VF1
Dispensing VM 110, referred to as such as VNIC1, and VF2 106 is distributed into VM 110, such as referred to as VNIC2.
Need VF's according to used in the self-demands of VM 110 reset VM 110 on VM 110 after electricity
MAC Address, the process step of flow elements refers to Fig. 4.
Fig. 4 illustrates that master operating system (is for example referred to as the first child-operation with the sub-operating system in VM 110
System) between interaction.
1st, after electronic equipment starts successfully, master operating system is built by OVS with the first sub-operating system first
Vertical communication port.
2nd, after the communication port is successfully constructed, the first sub-operating system is needing the MAC of setting Microsoft Loopback Adapter
When address (such as needing to set VNIC1 MAC Address and VNIC2 MAC Address), lead to
Cross the communication port set up to ask to master operating system send configuration, the new of VF is carried in configuring request
MAC Address.
After send configuration request, the first sub-operating system can start timer, wait master operating system hair
The response message sent.
3rd, master operating system receives configuring request by communication port, parses configuring request, it is determined that configuration please
Seek the content of middle carrying.
4th, master operating system sends response message to the first sub-operating system.
Master operating system judges the validity of configuring request according to the configuration information of itself, if in configuring request
The parameter error of carrying, then master operating system can be to the first sub-operating system transmission response message, the response
Message is used to indicate configuration information change failure.If configuring request is correct, master operating system can basis
The type of message of configuring request, calls IOCTRL interfaces to issue MAC configuration informations respectively to NIC1 100
With NIC2 102 (reference can be made to arrow in Fig. 3), complete MAC Address and set.
Master operating system judges whether configuration succeeds by the returning result of reception, and construction issues the first son behaviour
Make the response message of system, the response message is sent to the first sub-operating system, the response message is used to indicate
MAC Address changes success or failure.
Wherein, the first sub-operating system can start timer, to wait sub- behaviour after send configuration request
Make the response message of system.If before timer expiry, the first sub-operating system have received main operation system
System sends response message, then the first sub-operating system stops timer, the content of response message is parsed, with true
Determine MAC Address to change successfully or fail.
If it is determined that MAC Address is changed successfully, then the first sub-operating system can terminate this configuration setting
Flow.If in timer expiry, the first sub-operating system does not receive response message also, or receive
Response message indicates MAC Address change failure, then it represents that mistake is occurred in that in configuration process, then VNIC1
Possibly can not normally it be run with VNIC2, then the first sub-operating system can close the VNIC1 of this configuration
And VNIC2, prevent error diffusion.
Example 2：First sub-operating system initiates the masterslave switchover of bond mouthfuls of Microsoft Loopback Adapter.
Fig. 5 is referred to, an electronic equipment is connected by two physical network cards with Ethernet switch.The electricity
Two virtual machines (being for example referred to as VM1 110 and VM2 120), VM1 110 have been run in sub- equipment
It is connected respectively by OVS with master operating system with VM2 120, configuring request can pass through ether network packet
Form is interacted.Two pieces of physical network cards of the electronic equipment are respectively designated as NIC1 100 and NIC2 102,
Wherein NIC1 100 configures VF ports by SR-IOV, and such as NIC1 100 VF is VF1 104
With VF1 105, NIC2 102 VF ports, such as NIC2 102 VF are configured again by SR-IOV
For VF2 106 and VF2 107.VF1 104 and VF2106 are distributed into VM1 110, for example, claimed respectively
For VNIC1 and VNIC2, VF1 105 and VF2 107 are distributed into VM2 120, for example, are referred to as
VNIC3 and VNIC4.Wherein, VF1 104 and VF2 106 as VM1 110 active and standby bond, VF1
105 and VF2 107 as VM2 120 active and standby bond.Such as NIC1 100 is main physical network card, NIC2
102 be spare physical network interface card.
For example, needed on VM1 110 after electricity according to VM1 110 demands of itself reset VNIC1 and
VNIC2 active and standby bond information.
After electronic equipment starts successfully, master operating system and (VM1 110 operation of the first sub-operating system
System) and the second sub-operating system (VM2 120 operating system) pass through chain of command OVS respectively first
Mode set up communication port.
After the communication port is successfully constructed, the first sub-operating system is according to the demand of itself, it is necessary to initiate
Active and standby bond mouthfuls of VNIC1 and VNIC2 are switched, and the first sub-operating system is sent to master operating system matches somebody with somebody
Request is put, VNIC1 and VNIC2 bond masterslave switchover configuration informations are carried in the configuring request.
After send configuration request, the first sub-operating system can start timer, wait the response of master operating system to disappear
Breath.
Master operating system is received after configuring request, respectively to NIC1 100 and the issuing messages of NIC2 102, with
Indicate switching NIC1 100 and NIC2 102 active and standby bond states.
Master operating system judges NIC1 100 and NIC2 102 active and standby bond by the returning result of reception
Whether switching succeeds, and master operating system constructs the response for issuing the first sub-operating system according to the result of switching
Message.
If NIC1 100 and NIC2 102 active and standby bond is switched successfully, meanwhile, master operating system hair
Also have VNIC3 and VNIC4 on existing NIC1 100 and NIC2 102, therefore, master operating system except to
First sub-operating system is sent outside response message, can also be in the lump to the first sub-operating system and/or second
Sub-operating system sends a notification message, for indicating that NIC1 100 and NIC2 102 there occurs masterslave switchover.
If NIC1 100 and NIC2 102 active and standby bond handoff failures, master operating system is to first
Sub-operating system sends the response message for indicating handoff failure.
If it is determined that VNIC1 and VNIC2 active and standby bond is switched successfully, then the first sub-operating system can
To terminate the flow that this configuration is set.
In addition, if determine that VNIC1 and VNIC2 active and standby bond is switched successfully, then the second child-operation
System is also possible to receive the notification message of master operating system transmission, then the second sub-operating system can be logical according to this
Know message to set VNIC3 and VNIC4 activestandby state.
If the first sub-operating system does not receive response message, or the response received also in timer expiry
Message indicates VNIC1 and VNIC2 active and standby bond handoff failures, then it represents that occurred in that in configuration process
Mistake, then VNIC1 and VNIC2 possibly can not normally be run, then the first sub-operating system can be closed
The VNIC1 and VNIC2 of this configuration, prevent error diffusion.
Example 3：First sub-operating system initiates the setting of VLAN marks.
It (is respectively VM1 for example to refer to and 4 virtual machines have been run on Fig. 6, an electronic equipment
418~VM4 424), each virtual machine has the VF of oneself to be connected with physical network card NIC1, wherein,
VM1 418 manages the configuration of each virtual machine internal, system as the management node in this 4 virtual machines
The information such as meter.Wherein 420~VM4 of VM2 424 have 1 VF (VF2~VF4) to be connected to physics respectively
On network interface card NIC1, the external network interface of virtual machine is used as.418~VM4 of VM1 424 lead to master operating system
Cross OVS bridging communications.
The VF according to used in the configuration needs of user reset VM2~VM4 is needed on VM1 418 after electricity
Port vlan information.
After electronic equipment starts successfully, master operating system passes through chain of command first with each sub-operating system
OVS mode sets up communication port.After communication port is successfully constructed, VM1 418 operating system (example
Such as be referred to as the first sub-operating system) as management node, it is necessary to set the VLAN of each virtual machine.First
Sub-operating system is asked to master operating system send configuration, and the configuring request is used to ask configuration VF2~VF4
VLAN.After send configuration request, the first sub-operating system can start timer, wait main operation
The response message of system.
Master operating system is received after the configuring request of the first sub-operating system transmission, to NIC1 issuing messages,
VLAN for configuring VF2~VF4, master operating system by receive returning result judge configuration whether into
Work(, and send response message to the first sub-operating system.
Before timer expiry, if the first sub-operating system have received response message, stop timer,
The content of response message is parsed, if configuration successful, the first sub-operating system can be distinguished by chain of command
Send a notification message to 420~VM4 of VM2 424, i.e., send a notification message respectively and give VM2 420~VM4
424 operating system, terminates the flow that this configuration is set.If the first child-operation in timer expiry
System does not receive response message, or response message is used to indicate configuration failure, then the first sub-operating system stops
This VLAN setting procedure.
If 420~VM4 of VM2 424 receive the notification message from the first sub-operating system, according to notice
The vlan information of the port of the storage of the content update of message locally, configuration take-effective.
