Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, 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.
The method, apparatus and electronic device for adjusting the QoS of the VF according to the present invention are described below with reference to fig. 1-6.
The VF QoS adjusting method provided by the embodiment of the invention is mainly applied to Virtual Machines (VMs). The method for adjusting the QoS of the VF according to the embodiment of the present invention is described below with a virtual machine as an execution subject.
As shown in fig. 1, the method for adjusting the QoS of the VF according to the embodiment of the present invention mainly includes step 110 and step 120.
It should be noted that N target VFs are configured on the same target virtual port, and N is a positive integer greater than 1, for example, N is 2.
In some embodiments, one target virtual port may flexibly mount multiple target VFs to a virtual machine, and one virtual port corresponds to multiple target VFs, thereby improving VF redundancy. When one target VF in one target virtual port has a fault, the fault can be replaced by other VFs, so that the reliability of the virtual machine is improved.
The OpenStack is an open-source cloud computing management platform project and is a combination of a series of software open-source projects. After the SR-IOV is introduced, openStack can directly associate a VF through an SR-IOV virtual port. In other embodiments, it is also compatible with the prior art scheme that one virtual port corresponds to one VF.
In some embodiments, the local area network MAC addresses and the virtual local area network VLANs of the N target VFs are all the same. Namely, the MAC addresses and VLANs between the N target VFs are all the same, which can avoid the problem that security detection needs to be closed during aggregation, and improve security.
For example, one target virtual port has 2 target VFs, the MAC address of VF1 is the same as the MAC address of VF2, and the VLAN of VF1 is the same as the VLAN of VF 2.
In this case, as shown in fig. 2 and fig. 3, one target virtual port mounts two target VFs, a Host bond (Host node group bond, mode 4) includes a Network Interface Controller (NIC) 1 and an NIC2, a Link Aggregation Control Protocol LACP (Link Aggregation Control Protocol) is started, the NIC1 is connected to the ETH0 through the VF1, and the NIC2 is connected to the ETH1 through the VF 2.
Inside the virtual machine, the Guest bond (virtual machine group bond, mode is 2) aggregates ETH0 and ETH1, and closes LACP, thereby implementing that one virtual port mounts two VFs.
In the embodiment, by configuring a plurality of target VFs for one target virtual port, the L2 redundancy of the SR-IOV is improved, the single-point failure of the virtual machine is solved, the reliability of the virtual machine is improved, the MAC addresses and the VLANs of the plurality of target VFs are the same, the security trust switch does not need to be turned on, and the security is improved.
As can be appreciated, the states of the SR-IOV portal have two states, up and down. For example, the first state may be the up state.
In some embodiments, the network port state of the SR-IOV to which each target VF belongs may be detected by a Neutron-sriov-agent corresponding to the Neutron component of the virtual machine, so as to determine that the network port state of the SR-IOV in the N target VFs is the first number of the target VFs in the first state.
For example, N is 2. The first state is the up state, and if it is detected that only one state of the target VF is the up state, the first number is 1.
And step 120, based on the first quantity, adjusting the QoS bandwidth speed limit values of the N target VFs.
In this case, the QoS bandwidth speed limit values of the N target VFs may be automatically reallocated and adjusted according to the QoS bandwidth speed limit value corresponding to the current target virtual port.
In some embodiments, the first state is an up state, and the adjusting the QoS bandwidth speed limit values of the N target VFs based on the first number includes averagely allocating the target QoS bandwidth speed limit values to the target VFs whose first state is the up state, and configuring the QoS bandwidth speed limit value of the target VF whose first state is a down state among the N target VFs to be 0.
It should be noted that the target QoS bandwidth speed limit value is the maximum QoS bandwidth speed limit value of the target virtual port.
For example, the QoS bandwidth limit of the current target virtual port is Q, and the QoS bandwidth limit of the N target VFs may be configured to be Q/N before detection.
If the network port states of the SR-IOVs of the N target VFs are detected respectively, and the network port states of the M target VFs obtained through detection are converted from the up state to the down state, the first number is N-M, where M is a positive integer greater than or equal to 1 and less than N.
In this case, the Neutron-sriov-agent updates the QoS bandwidth speed limit values of the target VFs, and may configure the maximum QoS bandwidth speed limit values of the target virtual ports to which the N-M target VFs are averagely allocated.
In other words, the QoS bandwidth speed limit values of the N-M target VFs whose gateway states of the SR-IOVs are up states are updated to Q/(N-M), and the QoS bandwidth speed limit values of the M target VFs whose gateway states of the SR-IOVs are down states are updated to 0.
In this embodiment, when M SR-IOV ports fail, the maximum QoS bandwidth limit value of the target virtual port averagely allocated to the N-M target VFs may be dynamically adjusted, and when the failure recovers, the maximum QoS bandwidth limit value of the target virtual port may be dynamically adjusted to the QoS bandwidth limit value in the normal state.
As shown in fig. 2, the QoS bandwidth speed limit value corresponding to the current target virtual port is Q, and N is 2. The first state is up state, and the QoS bandwidth speed limit value of each target VF is Q/2.
As shown in FIG. 3, if it is detected that the state of only one target VF is up, the first number is 1. The QoS bandwidth speed limit value of the target VF with the up state can be adjusted to Q/1 from Q/2, namely Q. While the QoS bandwidth limit of the target VF whose state is down can be adjusted to 0 by Q/2.
According to the VF QoS adjusting method provided by the embodiment of the invention, a plurality of target VFs are configured for one target virtual port, the consistency of the QoS bandwidth speed limit values of the target virtual port can be kept, the QoS bandwidth speed limit values of the target VFs are adjusted by detecting the network port states of the target VFs, the QoS numerical value of each target VF can be flexibly adjusted according to the network card state, and the stability of the bandwidth speed limit values when a single point of network port fails is ensured.
In some embodiments, after adjusting the QoS bandwidth limit values of the N target VFs based on the first number, the method further includes re-determining, according to the target period, the number of the target VFs whose states of the SR-IOV ports belong in the N target VFs are the first state.
It can be understood that the number of the failed internet access and the number of the normal internet access can be continuously and timely determined according to the target period, and then the distribution of the QoS bandwidth speed limit values of the target VFs can be timely adjusted.
And under the condition that the number of the currently determined target VFs is the same as that of the target VFs determined last time, maintaining the QoS bandwidth speed limit value of each target VF unchanged.
And under the condition that the number of the currently determined target VFs is different from the number of the target VFs determined last time, readjusting the QoS bandwidth speed limit values of the N target VFs based on the number of the currently determined target VFs.
For example, in the last detection process, if the port states of the SR-IOVs of the N target VFs are detected, and the detected port states of the M target VFs are converted from the up state to the down state, the first number is N-M, where M is a positive integer greater than or equal to 1 and less than N.
In the detection process, if the SR-IOV network port state of Y target VFs among the M target VFs is restored to the up state, the maximum QoS bandwidth speed limit value of the target virtual port may be evenly distributed to each target VF whose SR-IOV network port state is the up state, and the QoS bandwidth speed limit values of the remaining target VFs are set to 0.
In this case, the QoS bandwidth speed limit values of (N-M + Y) target VFs whose SR-IOV portal state is up state may be set to Q/(N-M + Y), and the QoS bandwidth speed limit values of (M-Y) target VFs whose remaining SR-IOV portal state is down state may be set to 0.
In this embodiment, the SR-IOV port status of the target VF can be continuously detected, and the QoS bandwidth speed limit value of each target VF can be timely adjusted when the new port of the target VF fails, so as to ensure the stability of the bandwidth speed limit value when the port fails.
In some embodiments, before determining that the state of the single root I/O virtualization SR-IOV port to which the N target virtual functions VF belongs is the first number of target VFs in the first state, the method for adjusting QoS of VFs according to the embodiment of the present invention further includes: and configuring the QoS bandwidth speed limit value of the target virtual port as a target QoS bandwidth speed limit value, and generating a virtual port update event.
In this embodiment, the maximum QoS bandwidth speed limit value may be configured for the target virtual port by calling an API (Application Program Interface) of the Neutron-server, and a virtual port update event is generated and sent to the Neutron-sriov-agent.
In the event that Neutron-sriov-agent receives an update notification of a virtual port update event, neutron-sriov-agent evenly distributes the target QoS bandwidth rate limit values to the N target VFs. Wherein, the first state of the N target VFs is the up state.
In this case, if the maximum QoS bandwidth speed limit is Q, the QoS bandwidth speed limit of each target VF is configured to be Q/N, so that the QoS bandwidth speed limit of each target VF of the target virtual port is the same.
In some embodiments, before configuring the QoS bandwidth speed limit value of the target virtual port as the target QoS bandwidth speed limit value, the method for adjusting the QoS of the VF according to the embodiment of the present invention further includes: and receiving the input of a user, and determining the QoS bandwidth speed limit value strategy of the target virtual port.
It will be appreciated that the QoS bandwidth speed limit policy for the target virtual port may be determined by receiving an operation of a user invoking the API of the neutron-server component to create the QoS bandwidth speed limit policy through the front-end user interface.
In this case, the specific value of the target QoS bandwidth speed limit may be determined based on the QoS bandwidth speed limit policy of the target virtual port.
In this embodiment, the QoS bandwidth speed limit policy of the target virtual port may be determined in a user-defined manner, so as to facilitate determination of the QoS bandwidth speed limit of each target VF.
As shown in FIG. 4, in some embodiments, after a virtual machine having SR-IOV virtual ports is created, the N target VFs may be directly associated at one virtual port.
On the basis, a QoS bandwidth speed limit value strategy can be created by calling an API of the neutron-server component by a user, and a QoS bandwidth speed limit value rule, namely the maximum QoS bandwidth speed limit value, is set in the strategy.
After the maximum QoS bandwidth speed limit value is determined, an API of a Neutron-server can be called to configure the QoS bandwidth speed limit value strategy for the target virtual port, and an update event of the target virtual port is sent to the Neutron-sriov-agent.
And under the condition that the Neutron-sriov-agent receives the update notice of the virtual port update event, updating the QoS bandwidth speed limit value of each target VF, wherein the QoS bandwidth speed limit value of each target VF is configured to be Q/N.
And continuously detecting the network port state of the SR-IOV to which each target VF belongs according to the target period by the Neutron-sriov-agent, and updating the QoS bandwidth speed limit value of each target VF by the Neutron-sriov-agent if the detected network port states of the M target VFs are converted from the up state to the down state.
The QoS bandwidth speed limit values of the N-M target VFs of which the network port state of the SR-IOV is the up state are updated to Q/(N-M), and the QoS bandwidth speed limit values of the M target VFs of which the network port state of the SR-IOV is the down state are updated to 0.
In the process of continuing detection, if the SR-IOV portal states of Y of the M target VFs are restored to the up state, the Neutron-sriov-agent updates the QoS bandwidth speed limit value of each target VF.
The QoS bandwidth speed limit values of (N-M + Y) target VFs whose SR-IOV network port states are up states may be set to Q/(N-M + Y), and the QoS bandwidth speed limit values of (M-Y) target VFs whose remaining SR-IOV network port states are down states may be set to 0.
In the process of continuous detection, if the SR-IOV network port state of the target VF is detected to be changed, the QoS bandwidth speed limit value of each target VF is continuously updated, and the dynamic update of the QoS bandwidth speed limit value of the target VF is realized.
