目前，一个宿主机常常可以支持多个虚拟机，每个虚拟机都能为宿主机提供固态硬盘(Solid State Disk，简称：SSD)存储服务，为了确保每个虚拟机的I/O的服务质量(Quality of Service，简称：Qos)，如何对各个虚拟机进行流量控制成为了重点研究内容。At present, a host machine can often support multiple virtual machines, and each virtual machine can provide solid-state disk (SSD) storage services for the host machine.

However, when a user deploys multiple virtual machines of different service types at the same time, the user has different performance requirements for different virtual machines, and the traffic control results of the prior art are relatively fixed and cannot meet the actual control needs of the user.

下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本发明实施例进行描述。The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.
首先，对本申请所基于的虚拟机流量控制系统的结构进行说明：First, the structure of the virtual machine traffic control system on which this application is based is described:
本申请实施例提供的虚拟机流量控制方法、装置、电子设备及存储介质，适用于对部署在宿主机的虚拟机进行流量控制。如图1所示，为本申请实施例基于的虚拟机流量控制系统的结构示意图，主要包括多个虚拟机、数据采集装置和用于对虚拟机进行流量控制的虚拟机流量控制装置，其中，该虚拟机流量控制系统部署在宿主机。具体地，可以利用数据采集装置各个虚拟机的虚拟磁盘所对应的物理磁盘的属性信息和用户输入的虚拟机流量控制需求，然后再将采集到的数据发送到虚拟机流量控制装置，以使该虚拟机流量控制装置能够根据这些数据，对虚拟机进行流量控制。The virtual machine flow control method, device, electronic device and storage medium provided in the embodiments of the present application are suitable for flow control of virtual machines deployed on a host machine. As shown in Figure 1, it is a structural schematic diagram of the virtual machine flow control system based on the embodiments of the present application, which mainly includes multiple virtual machines, a data acquisition device and a virtual machine flow control device for flow control of virtual machines, wherein the virtual machine flow control system is deployed on the host machine. Specifically, the attribute information of the physical disk corresponding to the virtual disk of each virtual machine of the data acquisition device and the virtual machine flow control requirements input by the user can be used, and then the collected data can be sent to the virtual machine flow control device, so that the virtual machine flow control device can control the flow of the virtual machine according to these data.
本申请实施例提供了一种虚拟机流量控制方法，应用于宿主机，用于对部署在宿主机的虚拟机进行流量控制。本申请实施例的执行主体为电子设备，比如服务器、台式电脑、笔记本电脑、平板电脑及其他可用于对虚拟机进行流量控制的电子设备。The embodiment of the present application provides a virtual machine flow control method, which is applied to a host machine and is used to control the flow of a virtual machine deployed on the host machine. The execution subject of the embodiment of the present application is an electronic device, such as a server, a desktop computer, a laptop computer, a tablet computer, and other electronic devices that can be used to control the flow of a virtual machine.
如图2所示，为本申请实施例提供的虚拟机流量控制方法的流程示意图，该方法包括：As shown in FIG. 2 , a flow chart of a virtual machine traffic control method provided in an embodiment of the present application is shown, and the method includes:
步骤201，获取当前部署的各个虚拟机的虚拟磁盘所对应的物理磁盘的属性信息。Step 201: Acquire the property information of the physical disk corresponding to the virtual disk of each currently deployed virtual machine.
其中，物理磁盘的属性信息用于表征该物理磁盘的I/O服务能力，属性信息至少包括物理磁盘的IOPS上限值和带宽等相关信息。The attribute information of the physical disk is used to characterize the I/O service capability of the physical disk, and the attribute information at least includes relevant information such as the IOPS upper limit and bandwidth of the physical disk.
步骤202，按照用户虚拟机流量控制需求，根据各虚拟磁盘所对应的物理磁盘的属性信息，为各虚拟磁盘分配流量使用额度。Step 202: Allocate traffic usage quota to each virtual disk according to the traffic control requirements of the user virtual machine and the attribute information of the physical disk corresponding to each virtual disk.
需要说明的是，用户输入的虚拟机流量控制需求反映了各虚拟机在宿主机中的使用频率和重要程度等信息。It should be noted that the virtual machine traffic control requirements input by the user reflect information such as the usage frequency and importance of each virtual machine in the host machine.
具体地，首先可以按照用户虚拟机流量控制需求，确定各虚拟机在流量使用额度分配方面的权重，然后再结合各虚拟磁盘所对应的物理磁盘的属性信息，为当前宿主机上部署的各虚拟磁盘分配流量使用额度。Specifically, first, the weight of each virtual machine in the allocation of traffic usage quota can be determined according to the user virtual machine traffic control requirements, and then the traffic usage quota can be allocated to each virtual disk deployed on the current host machine in combination with the attribute information of the physical disk corresponding to each virtual disk.
步骤203，当任一虚拟磁盘的流量使用额度耗尽时，阻止该虚拟磁盘向对应的物理磁盘发送读写任务，以停止该虚拟磁盘的读写服务。Step 203: When the traffic usage quota of any virtual disk is exhausted, the virtual disk is prevented from sending read and write tasks to the corresponding physical disk to stop the read and write service of the virtual disk.
需要说明的是，在实际的网络环境中，若虚拟机出现超负荷运行，如接收的I/O任务超出了物理磁盘的实际服务能力等，将降低该虚拟机在宿主机中的I/O服务质量Qos。It should be noted that in an actual network environment, if a virtual machine is overloaded, such as the received I/O tasks exceed the actual service capacity of the physical disk, the I/O service quality Qos of the virtual machine in the host will be reduced.
具体地，当某虚拟机在运行一段时间后，耗尽了之前为其分配的流量使用额度，此时为了避免出现超负荷运行等情况，可以阻断该虚拟磁盘向对应的物理磁盘发送读写任务(I/O任务)，使该虚拟机无法向物理磁盘发送I/O任务，也就停止了该虚拟磁盘的读写服务。Specifically, when a virtual machine has exhausted the traffic usage quota previously allocated to it after running for a period of time, in order to avoid overload and other situations, the virtual disk can be blocked from sending read and write tasks (I/O tasks) to the corresponding physical disk, making it impossible for the virtual machine to send I/O tasks to the physical disk, thereby stopping the read and write services of the virtual disk.
在上述实施例的基础上，作为一种可实施的方式，在一实施例中，可以按照预设的额度更新周期，循环为各虚拟磁盘分配流量使用额度。Based on the above embodiment, as an implementable manner, in one embodiment, the traffic usage quota can be cyclically allocated to each virtual disk according to a preset quota update cycle.
具体地，在确定待为各虚拟机分配的流量使用额度的同时，还需要确定额度更新周期，后续按照该额度更新周期，循环为各虚拟磁盘分配流量使用额度。具体可以采用令牌桶技术，实现流量使用额度的循环分配。Specifically, when determining the traffic usage quota to be allocated to each virtual machine, it is also necessary to determine the quota update cycle, and then cyclically allocate traffic usage quotas to each virtual disk according to the quota update cycle. Specifically, token bucket technology can be used to achieve cyclic allocation of traffic usage quotas.
具体地，在一实施例中，虚拟磁盘包括虚拟磁盘处理器，用于向物理磁盘发送读写任务，具体可以在该虚拟磁盘待发送的读写任务上设置阻止标识，以使虚拟磁盘处理器不向物理磁盘发送该读写任务。Specifically, in one embodiment, the virtual disk includes a virtual disk processor for sending read and write tasks to the physical disk. Specifically, a blocking flag can be set on the read and write tasks to be sent by the virtual disk so that the virtual disk processor does not send the read and write tasks to the physical disk.
需要说明的是，虚拟磁盘在得到I/O任务后，将I/O任务添加到任务提交队列，以准备以队列的方式向物理磁盘发送I/O任务。It should be noted that after obtaining the I/O task, the virtual disk adds the I/O task to the task submission queue to prepare to send the I/O task to the physical disk in a queue manner.
具体地，在确定某虚拟磁盘的流量使用额度耗尽时，可以在其任务提交队列的标记位，添加阻止标识，以阻止该任务提交队列的发送操作，即不发送到对应的物理磁盘。Specifically, when it is determined that the traffic usage quota of a virtual disk is exhausted, a blocking flag can be added to the mark bit of its task submission queue to prevent the sending operation of the task submission queue, that is, not sending to the corresponding physical disk.
在上述实施例的基础上，作为一种可实施的方式，在一实施例中，在为各虚拟磁盘分配流量使用额度之后，方法还包括：Based on the above embodiment, as an implementable manner, in one embodiment, after allocating traffic usage quota to each virtual disk, the method further includes:
步骤301，监控各虚拟磁盘接收到的读写任务信息；Step 301, monitoring the read and write task information received by each virtual disk;
步骤302，针对每个虚拟磁盘，根据该虚拟磁盘接收到的读写任务信息，确定该虚拟磁盘的流量使用值；Step 302, for each virtual disk, determine the traffic usage value of the virtual disk according to the read and write task information received by the virtual disk;
步骤303，当该虚拟磁盘的流量使用值达到流量使用额度时，确定该虚拟磁盘的流量使用额度耗尽。Step 303: When the traffic usage value of the virtual disk reaches the traffic usage quota, it is determined that the traffic usage quota of the virtual disk is exhausted.
具体地，可以通过监控各虚拟磁盘接收到的读写任务信息，确定虚拟机在当前额度更新周期内的流量消耗情况，并确定其对应的流量使用值，在监控读写任务信息的过程中，比较虚拟磁盘的流量使用值和流量使用额度之间的关系，当该虚拟磁盘的流量使用值达到流量使用额度时，确定该虚拟磁盘的流量使用额度耗尽。Specifically, by monitoring the read and write task information received by each virtual disk, the traffic consumption of the virtual machine during the current quota update cycle and its corresponding traffic usage value can be determined. In the process of monitoring the read and write task information, the relationship between the traffic usage value and the traffic usage quota of the virtual disk is compared. When the traffic usage value of the virtual disk reaches the traffic usage quota, it is determined that the traffic usage quota of the virtual disk is exhausted.
其中，流量使用额度分为读写操作次数额度、读吞吐量额度和写吞吐量额度三种类型。Among them, traffic usage quotas are divided into three types: read and write operation quotas, read throughput quotas, and write throughput quotas.
相应地，虚拟磁盘的流量使用值包括IOPS累计值、读总吐量累计值和写吞吐量累计值三种指标，若该虚拟磁盘的IOPS累计值、读总吐量累计值和写吞吐量累计值中的任一指标达到对应类型的额度，则确定该虚拟磁盘的流量使用值达到流量使用额度。Correspondingly, the traffic usage value of the virtual disk includes three indicators: IOPS cumulative value, total read throughput cumulative value and write throughput cumulative value. If any of the indicators among the IOPS cumulative value, total read throughput cumulative value and write throughput cumulative value of the virtual disk reaches the quota of the corresponding type, it is determined that the traffic usage value of the virtual disk reaches the traffic usage quota.
示例性的，假定令牌更新时间(额度更新周期)为5ms，如果一个虚拟机的虚拟磁盘的流量使用额度中的读写操作次数额度为500K，读吞吐量额度为5000M/s，写吞吐量额度为4000M/s，则在一个额度更新周期(例如5ms)中，可以使用的令牌数量(流量使用额度)为2500IOPS，25000M度吞吐量,20000M写吞吐量。在实际应用中，这些流量使用额度参数可以基于物理磁盘的虚拟磁盘控制通道的私有Admin管理命令对各个虚拟磁盘进行设置，并且只有物理磁盘的虚拟磁盘控制通道具备这个设置权限。For example, assuming that the token update time (quota update cycle) is 5ms, if the read and write operation quota in the traffic usage quota of a virtual disk of a virtual machine is 500K, the read throughput quota is 5000M/s, and the write throughput quota is 4000M/s, then in a quota update cycle (e.g. 5ms), the number of tokens (traffic usage quota) that can be used is 2500IOPS, 25000M throughput, and 20000M write throughput. In actual applications, these traffic usage quota parameters can be set for each virtual disk based on the private Admin management command of the virtual disk control channel of the physical disk, and only the virtual disk control channel of the physical disk has this setting authority.
进一步地，在对虚拟机进行流量控制的过程中，各虚拟机独立进行Token(令牌)的维护，即每当收到一个I/O请求时，IOPS令牌数减1，read/write Thoughput Token(读/写总吐量)也减去请求的长度。Token先到达者(流量使用额度先耗尽者)，停止服务，直到这个时间片(额度更新周期)结束。新的时间片到达时，将重新进行令牌资源的初始化分配，即重新为各虚拟磁盘分配流量使用额度。Furthermore, in the process of flow control for virtual machines, each virtual machine independently maintains the token, that is, every time an I/O request is received, the number of IOPS tokens is reduced by 1, and the read/write throughput token is also reduced by the length of the request. The one whose token arrives first (the one whose traffic usage quota is exhausted first) stops serving until the end of this time slice (quota update cycle). When a new time slice arrives, the token resources will be re-initialized, that is, the traffic usage quota will be re-allocated to each virtual disk.
示例性的，在监控各虚拟磁盘接收到的读写任务信息时，可以基于各虚拟机的虚拟磁盘处理器DM对虚拟磁盘的读写任务进行计数，因此涉及信息同步问题，假设用户虚拟机流量控制需求对读写任务计数的精度要求不高，因此采用每个CPU(虚拟磁盘处理器)独享一个变量的方式来处理，即虚拟磁盘处理器中的一个DM实例给虚拟磁盘保留一个Random，如IOPS令牌计数、读总吞吐量令牌计数和读总吞吐量令牌计数中的任意一个。Exemplarily, when monitoring the read and write task information received by each virtual disk, the read and write tasks of the virtual disk can be counted based on the virtual disk processor DM of each virtual machine, which involves information synchronization issues. Assuming that the user virtual machine traffic control requirements do not require high accuracy in the read and write task counting, each CPU (virtual disk processor) is treated as having an exclusive variable, that is, a DM instance in the virtual disk processor reserves a Random for the virtual disk, such as any one of the IOPS token count, the total read throughput token count, and the total read throughput token count.
进一步地，对于每个DM实例，在对虚拟磁盘的读写任务进行计数的过程中，每当收到一个SQM请求(I/O任务)之后，进行计数更新，且只更新自己CPU的令牌计数。更新完成后，同时获取其他DM实例的变量，进行累加，以根据累加结果，确定当前虚拟磁盘的流量使用额度是否用完。用完后进行反馈控制，关掉当前的虚拟磁盘VF的I/O服务SQ。为了能够支持1个虚拟磁盘控制通道PF+127VF，虚拟磁盘控制器有8个DM，需要1024个数组，每个数组3个元素对应3种令牌值；还需要有128个数组用于存放定时更新令牌桶的令牌reload值(重置值)，同样每个数组有个3个元素，即读写操作次数额度、读吞吐量额度和写吞吐量额度，也称最大IOPS令牌值、最大读读吞吐量令牌值和最大写吞吐量令牌值。Furthermore, for each DM instance, in the process of counting the read and write tasks of the virtual disk, each time an SQM request (I/O task) is received, the count is updated, and only the token count of its own CPU is updated. After the update is completed, the variables of other DM instances are obtained at the same time and accumulated to determine whether the traffic usage quota of the current virtual disk is used up according to the accumulated results. After it is used up, feedback control is performed to turn off the I/O service SQ of the current virtual disk VF. In order to support 1 virtual disk control channel PF+127VF, the virtual disk controller has 8 DMs, requiring 1024 arrays, each with 3 elements corresponding to 3 token values; 128 arrays are also required to store the token reload value (reset value) of the timed update token bucket, and each array also has 3 elements, namely the read and write operation quota, the read throughput quota and the write throughput quota, also known as the maximum IOPS token value, the maximum read-read throughput token value and the maximum write throughput token value.
需要说明的是，在一个DM收到SQM请求后，获取不同SQ(I/O服务)命令中的对应SQE字段，根据物理SQ到虚拟SQ的映射表映射得到对应的VF，给这个(DM,VF)组合的元素累加额度值，加完之后，判断这个VF在所有DM上的额度累加值是否超过对应的令牌额度值，若是，则关掉这个VF的所有SQ。当到达令牌桶更新时间(额度更新周期)时，每个DM分别收到时间中断，每个DM更新自己CPU上的数据结构，使对应变量(指标)的累加值清零。其中，每个DM实例可以设置有一个定时器，在定时器中断中置位所有DM的reload flag(重置标识)，DM在循环中检测reload flag做reset重置操作即将当前每个VF的流量使用值量进行清零。It should be noted that after a DM receives an SQM request, it obtains the corresponding SQE field in different SQ (I/O service) commands, maps the corresponding VF according to the mapping table from physical SQ to virtual SQ, and adds the quota value to the elements of this (DM, VF) combination. After the addition, it determines whether the accumulated quota value of this VF on all DMs exceeds the corresponding token quota value. If so, all SQs of this VF are turned off. When the token bucket update time (quota update cycle) is reached, each DM receives a time interrupt respectively, and each DM updates the data structure on its own CPU to clear the accumulated value of the corresponding variable (indicator). Among them, each DM instance can be set with a timer, and the reload flag (reset flag) of all DMs is set in the timer interrupt. The DM detects the reload flag in the loop and performs a reset operation to clear the current traffic usage value of each VF.
进一步地，虚拟磁盘的每一个SQ对应一个32bit寄存器，称为SQEARBCTL，其中有一个bit为SKIP(标记位)，当置为1时，此SQ不再参与命令分发的仲裁，即此SQ中的命令不会再发相应的固件。当该虚拟磁盘的流量使用额度用完时DM找到这个VF对应的所有SQ，将SKIPbit置为1，关掉后续的请求。到时间片结束时，DM将要重新设置每一个VF对应的SQEARBCTL的SKIP bit。Furthermore, each SQ of the virtual disk corresponds to a 32-bit register called SQEARBCTL, which has a bit for SKIP (mark bit). When it is set to 1, this SQ no longer participates in the arbitration of command distribution, that is, the commands in this SQ will no longer send the corresponding firmware. When the traffic usage quota of the virtual disk is used up, the DM finds all the SQs corresponding to this VF, sets the SKIP bit to 1, and turns off subsequent requests. At the end of the time slice, the DM will reset the SKIP bit of the SQEARBCTL corresponding to each VF.
需要进一步说明的是，当分配的流量使用额度比较小时，可能存在比较大的误差，原因是流量控制是通过开关队列的方式进行流量限定的，但是在设定流量使用额度比较小时，将频繁进行流量使用额度重置的操作，在操作的过程中，漏进来的I/O任务对当前误差的影响就比较明显，为了减小这个误差，可以通过减少开关的次数，来减少漏入的I/O任务。It should be further explained that when the allocated traffic usage quota is relatively small, there may be a relatively large error. The reason is that traffic control limits traffic by switching queues. However, when the set traffic usage quota is relatively small, the traffic usage quota will be frequently reset. During the operation, the impact of the leaked I/O tasks on the current error is more obvious. In order to reduce this error, the number of switches can be reduced to reduce the leaked I/O tasks.
具体地，当流量使用额度小于某个阈值时，可以增大额度更新周期，在实际测试中发现100ms是一个相对比较好的额度更新周期。Specifically, when the traffic usage quota is less than a certain threshold, the quota update period can be increased. In actual tests, it was found that 100ms is a relatively good quota update period.
