Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are intended to be illustrative only and are not intended to be limiting. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
English and term interpretation:
sriov: a hardware-based virtualization solution allows PCIe devices, such as network cards, to be shared between virtual machines.
PCIe: high-speed serial computer expansion bus standard (Peripheral Component interconnect express)
VF (virtual function): virtual function, a lightweight PCIe function.
Virtio: the virtualization solution is an I/O para-virtualization solution, is a set of programs for virtualization of general I/O equipment, and is an abstraction of a group of general I/O equipment in the para-virtualization Hypervisor.
Mac (media Access Control address) address: a MAC address.
The invention provides a method, a device, electronic equipment and a storage medium for creating a virtual machine based on address multiplexing of a Sriov network card. Specifically, the device details can be obtained from a neutron-server by using the MAC address and the pci-slot parameter at the neutron-sriov-nic-agent, so that the searched port address is unique and correct.
With reference to fig. 2, a virtual machine creation method based on Sriov network card address multiplexing according to an embodiment of the present invention is described, including the steps of:
s1, a command to create a virtual machine at a specified port is received.
nova specifies that a port creates a virtual machine, and the nova requests the neutron-server to acquire port related information, such as vif _ type, vif _ details and other information. Neutron-server returns the requested information to nova. And entering the next step after the information verification is successful.
And S2, creating a virtual machine, and creating an Sriov network card for the created virtual machine.
nova starts to create a virtual machine and creates a Sriov network card.
S3, obtaining the MAC address and the pci-slot parameter of the appointed port, obtaining the port number of the appointed port according to the MAC address and the pci-slot parameter, and configuring the Sriov network card according to the port number.
The port number is uniquely determined by the MAC address and the pci-slot parameter.
After detecting that the VF changes, the neutron-sriov-nic-agent acquires the device details from the neutron-server through the detected mac address and the pci-slot parameter to configure the VF.
And after the network card is updated locally by the neutron-sriov-nic-agent, informing the neutron server port to be online, and after receiving the message, the neutron-server sends updated port information to the nova.
Preferably, a physical network card of the Sriov network card generates a VLAN tag when supporting the inter-VF data packet exchange. To implement the real data exchange between 2 virtual machines with the same MAC address, it is necessary to make a vlan tag, such as an X710 network card, when the physical network card supports the internal vf exchange packet.
Thus, when a Neutron REST API is called to create 2 pci-sriov type ports, and the MAC addresses of the two ports are completely the same, the prior art can cause that after a virtual machine is created, if the network card information inquired by the Neutron-server is incorrect, the virtual machine returns an error. The invention can successfully create the virtual machine, and the MAC address is multiplexed.
The embodiment of the invention provides a virtual machine creating device based on Sriov network card address multiplexing, which comprises:
the receiving module is used for receiving a command of creating a virtual machine at a specified port;
the system comprises a creating module, a transmitting module and a receiving module, wherein the creating module is used for creating a virtual machine and creating an Sriov network card for the created virtual machine;
and the configuration module is used for acquiring the MAC address and the pci-slot parameter of the specified port, acquiring the port number of the specified port according to the MAC address and the pci-slot parameter, and configuring the Sriov network card according to the specified port number.
