Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, and form a application's part, schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Figure 1 shows that the physical network card of the embodiment of the present invention 1 invents the method flow diagram of multiple Microsoft Loopback Adapter;
Figure 2 shows that the physical network card of the embodiment of the present invention 2 invents the system construction drawing of multiple Microsoft Loopback Adapter.
Embodiment
Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Figure 1 shows that the physical network card of the embodiment of the present invention 1 invents the method flow diagram of multiple Microsoft Loopback Adapter, comprise the following steps:
Step 101: in advance preliminary treatment is carried out to virtual processing server;
Carrying out pretreated mode to virtual processing server is in advance: before described virtual processing server starts, the physical network card selected in advance is arranged on the quick interconnected PCIE slot of external components of described virtual processing server.
Such as: Intel X520 twoport network interface card and network card chip 82599 are arranged on virtual processing server NF5270M3PCIE slot.
Carrying out pretreated mode to virtual processing server is in advance: after described virtual processing server starts, arrange virtual parameter state.
After described virtual processing server starts, be: after described virtual processing server starts, by entering basic input-output system BIOS that Intel Virtualization Technology parameter is set for opening to the process that virtual parameter state is arranged.
Carrying out pretreated mode to virtual processing server is in advance: after described virtual processing server starts, installation targets operating system; Wherein, described destination OS refers to: red cap operating system 6.0.
Specifically: after described virtual processing server starts, install red cap operating system 6.0, default installation, when in the end selecting installation kit, all bags are all selected to install, and guarantee that Linux KVM module, storehouse, user instrument are all installed.
After described virtual processing server starts, after red cap operating system 6.0 is installed, also comprise:
Use power user's account and root Account Logon server, this configuration file of amendment/boot/grub/menu.ls t, adds intel_iommu=on later.
Because give tacit consent to red cap system distribution version for I/O Memory Management Unit (input and output memory management unit) acquiescence close, when distributing virtual functions for virtual machine, I/OMMU needs to open, and after having changed above-mentioned parameter, restarts virtual processing server and comes into force.
Step 102: when triggering the event generation of establishment Microsoft Loopback Adapter, described virtual processing server Automatically invoked Microsoft Loopback Adapter creates order, for the physical network card selected in advance, generate one or more Microsoft Loopback Adapter and distribute corresponding physical address according to default allocation strategy to described one or more Microsoft Loopback Adapter;
Trigger the situation creating the generation of Microsoft Loopback Adapter event to refer to: the establishment Microsoft Loopback Adapter button on described virtual processing server is triggered or creates the Preset Time arrival of Microsoft Loopback Adapter.
The process that described virtual processing server distributes corresponding physical address to described one or more Microsoft Loopback Adapter according to default allocation strategy is:
Described virtual processing server distributes corresponding physical address to described one or more Microsoft Loopback Adapter to physical address corresponding to described one or more Microsoft Loopback Adapter Random assignment or Automatically invoked command tools respectively.
The physical function of Intel X520 network interface card and the driving of virtual functions in red cap system are named with ixgbe and ixgbevf respectively, the every at most port of X520 network interface card can support 63 Microsoft Loopback Adapters, can pass through ixbge drive load time parameter max_vfs when Microsoft Loopback Adapter creates.
Microsoft Loopback Adapter creates order: modprobe ixgbe max_vfs=4;
Use lspci order can confirm that the every port of mentioned order creates 4 Microsoft Loopback Adapters;
Order lspci | grep 82599.
During generating virtual network interface card, ixgbe can distribute a physical address at random each Microsoft Loopback Adapter, and restarting physical address may change at every turn.The ip command tools of Linux can be used for Microsoft Loopback Adapter assignment of allocation physical address, guarantees that the physical address distributed is unique, otherwise can cause network connection failure.Use following command tools to each Microsoft Loopback Adapter setting physical address:
Command tools: ip link set eth3vf 0mac aa:bb:cc:dd:ee:ff;
Utility command checks that confirmation is allocated successfully, order: ip l ink show eth3.
Step 103: described virtual processing server, according to default selection strategy, calls the Microsoft Loopback Adapter of establishment, processes business.
Described virtual processing server, according to default selection strategy, calls the Microsoft Loopback Adapter of establishment, to the mode that business processes is:
Described virtual processing server poll calls the Microsoft Loopback Adapter of establishment, processes business.
Described virtual processing server, according to default selection strategy, calls the Microsoft Loopback Adapter of establishment, to the mode that business processes is:
The Microsoft Loopback Adapter of described virtual processing server Selection and call least number of times, processes business.
Described virtual processing server, according to default selection strategy, calls the Microsoft Loopback Adapter of establishment, to the mode that business processes is:
Described virtual processing server Stochastic choice Microsoft Loopback Adapter created, processes business.
Figure 2 shows that the physical network card of the embodiment of the present invention 2 invents the system construction drawing of multiple Microsoft Loopback Adapter, comprising: physical network card, virtual processing server; Described physical network card is connected with described virtual processing server;
Described physical network card, for being connected with the slot of described virtual processing server;
Described virtual processing server, for when triggering establishment Microsoft Loopback Adapter event and occurring, Automatically invoked Microsoft Loopback Adapter creates order, for the physical network card selected in advance, generate one or more Microsoft Loopback Adapter and distribute corresponding physical address according to default allocation strategy to described one or more Microsoft Loopback Adapter; Also for according to default selection strategy, call the Microsoft Loopback Adapter of establishment, business is processed.
Compared to prior art, the method and system of multiple Microsoft Loopback Adapter are invented according to a kind of physical network card provided by the invention, realize single physical network card to invent multiple virtual network device for, solve the defect of physical resource deficiency, the utilance of raising hardware.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
