DPDK: the Data Plane Development Kit (Data Plane Development Kit) mainly operates based on a Linux system, is used for a function library and a drive set for rapidly processing Data packets, and can greatly improve the Data processing performance and throughput and improve the working efficiency of a Data Plane application program.
According to the embodiment of the application, a hot plug processing method of a virtual network card is provided.
Fig. 1 is a flowchart of a hot plug processing method of a virtual network card according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
step S101, detecting the insertion action of the target virtual network card.
For example, when the target virtual network card is inserted into the card slot, the insertion action of the target virtual network card is detected based on the linux kernel layer in the target virtual machine hierarchy.
Step S102, if it is detected that the target virtual network card is inserted into the kernel layer of the target virtual machine, configuration information of the target virtual network card is obtained.
For example, before the virtual network card a (corresponding to the target virtual network card in this application, the same applies below) is inserted into the kernel layer, the kernel layer already has a plurality of virtual network cards, obtains configuration information of the virtual network card a, and adds the virtual network card a to a plurality of virtual network card queues.
Optionally, in the hot plug processing method for a virtual network card provided in the embodiment of the present application, if it is detected that a target virtual network card is inserted into a kernel layer of a target virtual machine, acquiring configuration information of the target virtual network card includes: if the number of the virtual network cards is detected to increase in the kernel layer, confirming that the target virtual network card is inserted into the kernel layer of the target virtual machine; determining an adding event of a target virtual network card in a kernel layer; and acquiring the configuration information of the target virtual network card based on the adding event.
For example, the number of the virtual network cards in the kernel layer is 3, when the virtual network card a is inserted into the kernel layer, and when the increase of the number of the virtual network cards is detected in the kernel layer, it is determined that the virtual network card is inserted into the kernel layer of the target virtual machine, an event that the virtual network card a is added into the kernel layer is determined as an addition event of the virtual network card a, and the addition event of the virtual network card a includes a PCI address of a, where the configuration information of the target virtual network card at least includes the PCI address.
Optionally, in the hot plug processing method for a virtual network card provided in this embodiment of the present application, after determining an addition event of a target virtual network card in the kernel layer, the method further includes: adding the adding event into an event queue of the target virtual network card; acquiring an added event in the event queue according to a preset time length; storing the acquired adding event into an information table, wherein the information table at least comprises: configuration information of the target virtual network card and card board state information of the target virtual network card.
For example, adding an adding event of the virtual network card a into a time queue, detecting the adding event of the event queue every 1s (corresponding to a preset duration in the present application) by the control module 1, obtaining a PCI address of the virtual network card in the adding event of the virtual network card a, storing the PCI address into an information table of the virtual network card, setting an insertion state of a slot position daughter card in the current virtual network card (corresponding to card board state information of a target virtual network card in the present application), and adding the adding event into the event queue of the target virtual network card, so that the control module 1 can obtain the insertion state of the target virtual network card in real time, thereby improving the hot plug efficiency of the virtual network card.
For example, based on the information table of the virtual network card obtained by the control module 1, the information table at initialization is shown in the following table one:
watch 1
| Slot | Portid | Pci_addr | Mac_addr | Slot_status |
| 1 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty |
| 2 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty |
| 3 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty |
| 4 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty |
| 5 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty |
| 6 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty |
| 7 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty |
| 8 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty |
| 9 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty |
| 10 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty |
As shown in the first table, Slot represents a Slot number, starting from 1, 10 daughter cards are 1-10, port represents an id of a network card, starting from 0, a specific id is allocated by a DPDK module, Pci _ addr represents a Pci address of the network card, Mac _ addr represents a Mac address of the network card, Slot _ status represents an insertion state of the current Slot daughter card, Empty represents not inserted, and Present represents inserted.
When the information table already contains 3 virtual network cards before the virtual network card a is inserted into the kernel layer, the information table is as shown in the following table two:
watch two
| Slot | Portid | Pci_addr | Mac_addr | Slot_status | |
| 1 | 0 | 0000:00:03.0 | 52:54:00:01:8c:93 | |
|
| 2 | 1 | 0000:00:04.0 | 52:54:00:2b:2f: | Present | |
| 3 | 2 | 0000:00:05.0 | 52:54:00:2f:fd: | Present | |
| 4 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty | |
| 5 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty | |
| 6 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty | |
| 7 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty | |
| 8 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty | |
| 9 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty | |
| 10 | 0 | 0000:00:00.0 | 00:00:00:00:00:00 | Empty |
When the information table already contains 3 virtual network cards after the virtual network card a is inserted into the kernel layer, the information table is as shown in table three below:
watch III
Specifically, as can be seen from the above table three, the PCI address of the virtual network card a is 0000:00:06.0, and the card board status information is in a non-null state (there is a virtual network card insertion).
Step S103, the target virtual network card is processed in the DPDK module through the configuration information, and the processed target virtual network card is obtained.
For example, when monitoring that the card board state information in the table three is a virtual network card inserted according to a hot plug monitoring mechanism of the virtual network card, the control module 1 initializes slot4 (slot number 4), and after the initialization is completed, processes the virtual network card a corresponding to slot number 4 based on the DPDK module.
Optionally, in the hot plug processing method for a virtual network card provided in the embodiment of the present application, processing a target virtual network card in a DPDK module through configuration information, and obtaining the processed target virtual network card includes: if the card board state information of the target virtual network card is determined to be in a non-empty state through the information table, triggering the DPDK module to update the configuration information in the information table; and processing the target virtual network card based on the updated configuration information to obtain the processed target virtual network card.
For example, the DPDK module receives a notification that the target virtual network card sent by the control module has been inserted, acquires the PCI address of the virtual network card a based on the virtual network card information table, initializes the virtual network card based on the PCI address and configures the information, acquires the ID information of the virtual network card a and the MAC address information of the virtual network card a from the configured information of the virtual network card a, and updates the configured information of the virtual network card a into the information table.
The updated configuration information of the virtual network card a is shown in the following table four:
watch four
And step S104, creating a network card interface of the processed target virtual network card.
For example, after the configuration information of the virtual network card in the information table is updated, the control module 2 receives a notification that the virtual network card a is inserted into the card slot, which is sent by the control module 1, executes initialization processing of the logical Interface on the virtual network card a, and creates Interface information of the virtual network card a, for example, the Interface information of the virtual network card is Interface Ethernet 4/0.
Optionally, in the hot plug processing method for a virtual network card provided in the embodiment of the present application, the hierarchical structure of the target virtual machine at least includes: the virtual network card hot plug system comprises a kernel layer, a supporting layer and an application layer, wherein the application layer is used for displaying a network card interface, and the hot plug efficiency of the virtual network card is further improved by mutually matching the levels of a target virtual machine.
