Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Application scenarios of embodiments of the present invention are described below.
As shown in fig. 1, for example, one server is configured with two physical network cards, for example, a NIC 1108 and a NIC 2110, respectively, where the NIC 1108 configures a VF port through SR-IOV, for example, a VF of the NIC 1108 is a VF 1112, and the NIC 1110 also configures a VF port through SR-IOV, for example, a VF of the NIC 1112 is a VF 2114. Two virtual machines are started on the server, for example, VM 1100, VM 2102, VF 1112 is assigned to VM 1100, VLAN id of VF 1112 may be set to 10 when VM 1100 is started, VF 2114 may be assigned to VM 2102, and VLAN id of VF 2114 may be set to 20 when VM 2102 is started.
When the VM 1100 and the VM 2102 start to run, for example, the VM 1100 and the VM 2102 are required to communicate, the VM 1100 is required to set the VLAN id of the VF 1112 to be consistent with the VLAN id of the VF 2114. Under the existing mechanism, this operation can only be implemented by a Physical Function interface (PF) -VF mailbox (mailbox) message mechanism of hardware, for example, sending a message to the PF 1104 of the NIC 1108 through the VF 1112, so that the PF 1104 resets the VLAN id of the VF 1112.
It can be seen that, at present, when the configuration information (such as VLAN id) of the VF is changed, the hardware is heavily dependent, and the system cost is high.
The embodiment of the invention fully considers the problems, when the configuration information of the first virtual network card of the first virtual machine needs to be changed, the first virtual machine can send a configuration request to the main operating system, the main operating system can change the configuration information of the first virtual network card without the participation of additional hardware components, the system cost is saved, even if the hardware does not provide the operation of changing the corresponding configuration information, because the change of the configuration information does not depend on the hardware, the change of the configuration information is not influenced, the dependence degree of the hardware is reduced, even if the implementation modes of different network card manufacturers are inconsistent, different changes do not need to be made according to different hardware, the required operation is reduced, and the success rate of the change is improved.
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.
Referring to fig. 2, an embodiment of the present invention provides a method for changing configuration information of a virtual network card, and a flow of the method is described as follows.
Step 201: sending a configuration request to a main operating system running in the electronic equipment through a first virtual machine running in the electronic equipment; the configuration request is used for indicating the main operating system to change the configuration information of the first virtual network card of the first virtual machine;
step 202: and changing the configuration information of the first virtual network card into the first configuration information carried in the configuration request through the main operating system.
The electronic device may be, for example, a server, but may also be other types of electronic devices. One or more virtual machines run in the electronic device, for example, and the first virtual machine is any one of the virtual machines running in the electronic device.
The electronic device may have a Host operating system (Host OS) installed therein, where the Host operating system does not belong to any virtual machine, and a corresponding operating system may also run in a different virtual machine.
The physical network card of the electronic device provides virtual network card support for a virtual machine running in the electronic device through an IO virtualization technology (such as SR-IOV). Through the SR-IOV, one PF can be provided on a physical network card, and a plurality of VF interfaces can be provided at the same time. The PF is controlled by a main operating system in the electronic device and is mainly used for external communication requirements of a Host OS and configuration requirements of a physical network card and the like. The VF is controlled by a sub-operating system in the virtual machine.
Optionally, before sending the configuration request to the host operating system running in the electronic device through the first virtual machine running in the electronic device, the method further includes:
a communication channel between the host operating system and the first virtual machine is established through the host operating system.
That is, in order to implement communication between the host operating system and the first virtual machine, a communication channel between the host operating system and the first virtual machine needs to be established first. The communication channel between the main operating system and the first virtual machine may also be understood as a communication channel between the main operating system and the first sub-operating system.
Optionally, establishing, by the host operating system, a communication channel between the host operating system and the first virtual machine includes:
connecting a host operating system and a first virtual machine through an Open Virtual Switch (OVS) bridge by the host operating system; or
And connecting the main operating system with the first virtual machine through the serial interface of the management plane through the main operating system.
The embodiment of the invention does not limit how the communication channel is established between the main operating system and the first virtual machine.
For example, after the electronic device is powered on, the main operating system first completes initialization and configuration of the physical network card, and establishes a communication channel with the first virtual machine.
The first sub-operating system configures the characteristic of the first virtual network card according to the self requirement, and sends a configuration request to the main operating system through a communication channel between the first sub-operating system and the main operating system, wherein the configuration request can carry information of the first virtual network card used by the first sub-operating system and can carry configuration information of the first virtual network card by the first sub-operating system.
The destination MAC address of the configuration request may be a MAC address of a management port of the sub operating system, the source MAC may be a MAC address of the first virtual network card, the type of the configuration request may be a request message, and the configuration request may carry the requested content.
After receiving a configuration request sent by a first virtual machine, a main operating system sets corresponding configuration information of the first virtual network card according to the configuration information carried in the configuration request, and sends a configuration result to the first virtual machine through a response message, namely to a first sub-operating system, wherein the response message is used for indicating that the configuration information of the first virtual network card is changed successfully or unsuccessfully.
The destination MAC address of the response message may be a MAC address of the management port of the first sub-operating system, the type of the response message may be a response/notification message, and the response message carries the content of the response.
After the first sub-operating system sends the configuration request to the main operating system, the first sub-operating system may wait for a response message sent by the main operating system.
Optionally, after the first sub-operating system sends the configuration request to the main operating system, a timer may be started, and if the first sub-operating system receives the response message before the timer expires, the first sub-operating system parses the response message, so as to determine whether the configuration information of the first virtual network card is changed successfully or failed. And if the first sub-operating system does not receive the response message when the timer times out, the first sub-operating system can determine that the change of the configuration information of the first virtual network card fails, does not need to continue to wait, and can perform other work, so that the first sub-operating system is prevented from being in a waiting state all the time.
Optionally, the configuration information includes at least one of an MAC address of the first virtual network card, a VLAN in which the first virtual network card is located, and a working mode of the first virtual network card, and may also include any other possible configuration information of the first virtual network card; the working mode of the first virtual network card is used for indicating that the first virtual network card is a main virtual network card or a standby virtual network card of the first virtual machine.
The VLAN in which the first virtual network card is located includes, for example, an identifier (i.e., a VLAN identifier) of the VLAN in which the first virtual network card is located.
The following describes a method for changing the configuration information of the virtual network card according to an embodiment of the present invention by using several examples.
Example 1: and setting a scene of the MAC address of the first virtual network card for the first sub-operating system.
Referring to fig. 3, an electronic device is connected to an Ethernet Switch (Ethernet Switch) through two physical network cards. A virtual machine (for example, referred to as VM 110) is running in the electronic device, the VM 110 is connected to the host operating system through the OVS, and the configuration request may interact in the form of an ethernet message. The two physical network cards of the electronic device are named as NIC 1100 and NIC 2102, respectively, where the NIC 1100 configures a VF port through SR-IOV, for example, VF of NIC 1100 is VF 1104, and the NIC 2102 configures a VF port through SR-IOV, for example, VF of NIC 2102 is VF 2106. The VF 1104 is assigned to the VM 110, e.g., referred to as VNIC1, and the VF2106 is assigned to the VM 110, e.g., referred to as VNIC 2.
After the VM 110 is powered on, the MAC address of the VF used by the VM 110 needs to be reset according to the requirement of the VM 110 itself, and the processing steps in the flow part are shown in fig. 4.
FIG. 4 illustrates the interaction between the host operating system and the sub-operating system (e.g., referred to as the first sub-operating system) in VM 110.
1. After the electronic equipment is successfully started, the main operating system establishes a communication channel with the first sub-operating system through the OVS.
2. After the communication channel is successfully constructed, when the MAC address of the virtual network card needs to be set (for example, the MAC address of VNIC1 and the MAC address of VNIC2 need to be set), the first sub-operating system sends a configuration request to the main operating system through the established communication channel, where the configuration request carries the new MAC address of the VF.
After sending the configuration request, the first sub-operating system may start a timer and wait for a response message sent by the main operating system.
3. And the main operating system receives the configuration request through the communication channel, analyzes the configuration request and determines the content carried in the configuration request.
4. And the main operating system sends a response message to the first sub-operating system.
The main operating system judges the validity of the configuration request according to the configuration information of the main operating system, and if the parameters carried in the configuration request are wrong, the main operating system can send a response message to the first sub-operating system, wherein the response message is used for indicating that the configuration information is unsuccessfully changed. If the configuration request is correct, the host operating system may call the IOCTRL interface to issue MAC configuration information to the NIC 1100 and the NIC 2102, respectively, according to the message type of the configuration request (see the arrow in fig. 3), so as to complete the MAC address setting.
And the main operating system judges whether the configuration is successful or not through the received return result, constructs a response message sent to the first sub-operating system, and sends the response message to the first sub-operating system, wherein the response message is used for indicating the success or failure of the MAC address change.
After sending the configuration request, the first sub-operating system may start a timer to wait for a response message of the sub-operating system. If the first sub-operating system receives the response message sent by the main operating system before the timer is overtime, the first sub-operating system stops the timer and analyzes the content of the response message to determine whether the MAC address change is successful or failed.
If the MAC address is determined to be successfully changed, the first sub-operating system may end the process of the configuration setting. If the first sub-operating system does not receive the response message when the timer times out, or the received response message indicates that the MAC address change fails, indicating that an error occurs in the configuration process, VNIC1 and VNIC2 may not operate normally, and the first sub-operating system may close VNIC1 and VNIC2 configured this time, so as to prevent the error from spreading.
Example 2: the first sub-operation system initiates the main/standby switch of the virtual network card of the bond port.
Referring to fig. 5, an electronic device is connected to the ethernet switch through two physical network cards. Two virtual machines (for example, VM 1110 and VM 2120) are operated in the electronic device, VM 1110 and VM 2120 are connected to a host operating system through OVS, respectively, and configuration requests may interact in the form of ethernet messages. The two physical network cards of the electronic device are named as NIC 1100 and NIC 2102, respectively, where the NIC 1100 configures VF ports through SR-IOV, for example, VFs of the NIC 1100 are VF 1104 and VF 1105, and the NIC 2102 configures VF ports through SR-IOV, for example, VF of the NIC 2102 is VF2106 and VF 2107. VF 1104 and VF2106 are assigned to VM 1110, e.g., VNIC1 and VNIC2, respectively, and VF 1105 and VF 2107 are assigned to VM 2120, e.g., VNIC3 and VNIC4, respectively. Among them, VF 1104 and VF2106 are used as the primary and secondary bond of VM 1110, and VF 1105 and VF 2107 are used as the primary and secondary bond of VM 2120. For example, NIC 1100 is a primary physical network card and NIC 2102 is a backup physical network card.
For example, after VM 1110 is powered on, it is necessary to reset the master/slave bond information of VNIC1 and VNIC2 according to the requirement of VM 1110 itself.
After the electronic device is successfully started, the main operating system and the first sub-operating system (the operating system of the VM 1110) and the second sub-operating system (the operating system of the VM 2120) first establish communication channels by way of the control plane OVS, respectively.
After the communication channel is successfully constructed, the first sub-operating system needs to initiate main/standby switch of VNIC1 and VNIC2 according to its own requirements, and sends a configuration request to the main operating system, where the configuration request carries main/standby switch configuration information of VNIC1 and VNIC 2. After sending the configuration request, the first sub-operating system may start a timer, waiting for a reply message from the main operating system.
After receiving the configuration request, the host operating system sends a message to the NIC 1100 and the NIC 2102, respectively, to instruct to switch the host/standby bond states of the NIC 1100 and the NIC 2102.
The main operating system judges whether the main/standby bond switching between the NIC 1100 and the NIC 2102 is successful according to the received return result, and the main operating system constructs a response message to the first sub operating system according to the switching result.
If the main/standby bond of the NIC 1100 and the NIC 2102 is successfully switched, and at the same time, the main operating system finds that the VNIC3 and the VNIC4 are still on the NIC 1100 and the NIC 2102, so that the main operating system may send a notification message to the first sub-operating system and/or the second sub-operating system in addition to sending a response message to the first sub-operating system, for indicating that the main/standby switch of the NIC 1100 and the NIC 2102 occurs.
If the main/standby bond switching between the NIC 1100 and the NIC 2102 fails, the main operating system sends a response message indicating the switching failure to the first sub operating system.
If it is determined that the master/slave bond switching of VNIC1 and VNIC2 is successful, the first sub operating system may end the flow of the configuration setting.
In addition, if it is determined that the main/standby bond switching of VNIC1 and VNIC2 is successful, the second sub operating system may also receive a notification message sent by the main operating system, and the second sub operating system may set the main/standby states of VNIC3 and VNIC4 according to the notification message.
If the first sub-operating system has not received the response message when the timer times out, or the received response message indicates that the primary/standby bond switching of VNIC1 and VNIC2 fails, which indicates that an error occurs in the configuration process, VNIC1 and VNIC2 may not normally operate, and the first sub-operating system may close VNIC1 and VNIC2 configured this time, so as to prevent the error from spreading.
Example 3: the first sub-operating system initiates the setting of the VLAN identification.
For example, referring to fig. 6, 4 virtual machines (VM 1418 to VM 4424, respectively) are run on one electronic device, each virtual machine has its own VF connected to the physical network card NIC1, where the VM 1418 is used as a management node in the 4 virtual machines to manage configuration, statistics, and other information inside each virtual machine. The VMs 2420 to 4424 respectively have 1 VF (VF2 to VF4) connected to the physical network card NIC1, and serve as external network ports for the virtual machines. VMs 1418-4424 communicate with the host operating system through the OVS bridge.
After the VM 1418 is powered on, VLAN information of ports of the VFs used by the VMs 2 to 4 needs to be reset according to configuration requirements of users.
After the electronic device is successfully started, the main operating system and each sub operating system establish a communication channel in a control plane OVS mode. After the communication channel is successfully constructed, the operating system (for example, referred to as a first sub-operating system) of the VM 1418 serves as a management node, and the VLAN of each virtual machine needs to be set. The first sub-operating system sends a configuration request to the host operating system requesting configuration of the VLANs of VFs 2-4. After sending the configuration request, the first sub-operating system may start a timer, waiting for a reply message from the main operating system.
After receiving the configuration request sent by the first sub-operating system, the main operating system sends a message to the NIC1 for configuring the VLANs of the VFs 2 to VF4, and the main operating system determines whether the configuration is successful by receiving the returned result, and sends a response message to the first sub-operating system.
Before the timer is overtime, if the first sub-operating system receives the response message, the timer is stopped, the content of the response message is analyzed, and if the configuration is successful, the first sub-operating system can respectively send notification messages to the VMs 2420 to 4424 through the control surface, that is, the first sub-operating system respectively sends notification messages to the operating systems of the VMs 2420 to 4424, and the process of the configuration setting at this time is ended. And if the first sub-operating system does not receive the response message when the timer is overtime, or the response message is used for indicating that the configuration is failed, the first sub-operating system stops the VLAN setting process.
When the VM 2420 to VM 4424 receive the notification message from the first sub-operating system, the VLAN information of the locally stored port is updated according to the content of the notification message, and the configuration becomes effective.
The apparatus of the present invention will be described with reference to the accompanying drawings.
