Description
Technical field
The present invention relates to cloud operating system is virtualized, more particularly to a kind of single I/O virtualizations (SR-IOV,
Single-Root I/O Virtualization) virtual functions of the network interface under active and standby joint (bond) pattern (VF,
Virtual Function) ＆ physical functions (PF, Physical Function) activestandby state detection and synchronization
Method and device.
Background technology
SR-IOV standards allow efficiently to be shared between I/O guest domains quick peripheral component interconnect (PCIe,
Peripheral Component Interconnect Express) equipment.SR-IOV equipment can have tens of
The individual VF associated with certain PF.It is exactly that multiple cloud main frames share same support than more typical application
The PCIe network interfaces of SR-IOV standards, Fig. 1 is that two cloud main frames of the present invention share a SR-IOV network interface
Schematic network structure, as shown in figure 1, each cloud main frame can use one or more VF network interfaces, cloud
Share physical internet ports between main frame to complete to be interacted with external network.
In the scene very high to reliability requirement, the mode of the shared list physical internet ports of multiple cloud main frames can not
Meet the application demand of physical link level redundancy.For this scene, common solution is by SR-IOV
A pair of network interfaces composition bond active-standby modes (active-standby) of network interface, all cloud main frames of common service.
Fig. 2 enables SR-IOV network interface bond structural representations for cloud main frame of the present invention, as shown in Fig. 2 main frame exists
During establishment, two VF network interfaces of a pair of SR-IOV network interfaces can be simultaneously bound, the two VF network interfaces are due to thing
Different network interfaces are belonged in reason, it is possible to for the function that cloud main frame provides physical link redundancy.
Existing most of cloud operating systems all support the function of SR-IOV network interface bond, in actually used mistake
Cheng Zhong, cloud operating system is responsible for management and control this activestandby state to physical internet ports, and notifies that PF drives in real time more
Newly.Because the network interface of physical host has active and standby point, therefore, the cloud main frame that physical host is operated above just is needed
The activestandby state of network interface is paid close attention to, and needs to perceive the process of network interface active-standby switch, when VF and PF network interfaces
State is kept after synchronization, it is ensured that the promptness and accuracy of Message processing.
Realize that cloud main frame perceives the state of physical internet ports, it is necessary to which a set of VF drives and drives communication equipment with PF
System, but SR-IOV standards are not defined the realization mechanism of this communication line.The hardware of current main flow
Manufacturer can support that the communication characteristic, Fig. 3 show for Mailbox Communication Mechanism for Embedded of the present invention by the way of mail box notice
It is intended to, as described in Figure 3, comes to be realized for each VF by using a series of hardware mailbox and doorbell register
This communication channel.But, the VF based on mail box notice mode and PF that hardware vendor realizes in driving
Communication information between network interface is only limitted to VF and resets, configure VF MAC Address, arrange multicast address, set
Put VLAN filters, basic parameter settings such as maximum bag length etc. are set, these parameters are on cloud main frame
Using arriving when VF network interfaces are initialized when electric.
At present, it is also based on the channel of software and drives communication function with PF realizing that VF drives, but needs
Support is provided by Hypervisor subsystems.The implementation method of the channel of each manufacturer is simultaneously differed, because
This, needs client to initiate self these supports.And, it is not that Hypervisor productions commercial city used provides
Message mechanism based on software.
It can be seen that, for the VF＆PF network interface active/standby links synchronisation requirements in cloud main frame running, existing skill
Art cannot also be realized.
