Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Desktop Virtualization (VDI) refers to the virtualization of a computer's end system (also referred to as a desktop) to achieve security and flexibility of desktop use. Desktop systems belonging to our individual can be accessed over a network at any location and at any time through any device. And various physical devices are virtualized by utilizing a virtual technology, so that the utilization rate of resources is effectively improved, the cost is saved, and the application quality is improved. Under the support of the virtualization technology, the connection between the network software and the hardware equipment is more flexible, and the expandability is also greatly improved. The cloud desktop essentially stores and manages various user information in a unified way by using a virtualization technology, and through simple network access equipment, a user side can enter the cloud desktop to realize centralized management and realize efficient resource sharing.
VDI, in brief, virtualizes your desktop by running a Windows system on a cluster server in a data center. Users connect with virtual desktops (often referred to as virtual machines) through client computing protocols from client devices (zero terminals), users access their desktops through zero terminals just as traditional locally installed desktops, users can connect to their desktops at any time and anywhere, as long as there is a network, IT personnel can more easily manage desktop users and data, as all data is at the server, and the data of the clients is safer.
Referring to fig. 1, fig. 1 is a schematic diagram of a VDI architecture provided in the present disclosure, where a virtual machine may run in a cluster server, and a user may access, through a zero terminal, the virtual machine allocated to the virtual machine on the cluster server, thereby obtaining a desktop image, and control the obtained virtual desktop thereof in a reverse control manner. In fig. 1 it is exemplarily shown that a zero terminal 1 can access a virtual machine 1, that a zero terminal 2 can access virtual machines 2, … … and that a zero terminal N can be oriented to a virtual machine N.
With development and maturity of cloud computing, the use scene of the cloud desktop is wider and wider, and various industries such as universities, medical treatment, government and the like begin to gradually popularize the cloud desktop for office work, and the cloud desktop is an overall trend in the future.
For example, for an enterprise, a cluster server may be arranged to provide desktop services for a plurality of zero terminals. For some large enterprises, or for some enterprises that include multiple office locations, multiple cluster servers are often provided.
For virtualized architecture, virtual manifestations of server, storage, networking, etc. infrastructure are created by software technology. This enables IT organizations to run multiple virtual systems on a single server, allowing maximum use of computing resource utilization; however, the virtual machine services on a single server are different, so that the problems of blocking, even downtime and the like of all virtual machines on the server which belong to the server often occur due to insufficient server resources, and the use of users is affected.
For the problem, the common practice can only be that the user firstly gives the problem, and then the operation and maintenance personnel migrate the virtual machine on the server to the server with sufficient resources according to the existing conditions until the resources on the server are sufficient, so that the phenomenon of blocking and the like does not occur when the user uses the virtual machine.
The automatic migration method of the virtual machine provided by the embodiment of the disclosure can be applied to an automatic migration system of the virtual machine, and the automatic migration system of the virtual machine is introduced below.
Referring to fig. 2, fig. 2 is a schematic structural diagram of an automatic migration system of a virtual machine according to an embodiment of the present disclosure, where the automatic migration system of a virtual machine may include: cluster server, proxy server and zero terminal. Wherein the cluster server is exemplarily shown as cluster server 1, cluster servers 2, … … and cluster server N. Zero terminals are shown schematically as zero terminal 1, zero terminals 2, … … and zero terminal N. The automatic migration system of the virtual machine shown in fig. 2 is that a proxy (broker) server is added in the existing VDI system architecture, the proxy server is located between a cluster server and a zero terminal and is connected with a plurality of cluster servers and a plurality of zero terminals, all the cluster servers can be located in different local area networks in different areas, and the proxy server and each cluster server are in the same network. Each zero terminal can access the proxy server and obtain services from the proxy server. Each zero terminal can also access the corresponding cluster server through a login account.
According to the automatic migration method of the virtual machine, the proxy server can acquire the state information of the cluster server in the automatic migration system of the virtual machine in real time, and according to the state information and the resource information of the cluster server, whether the overload cluster server operated by overload exists currently or not is determined, the situation that the virtual machine operated by the overload cluster server is blocked or even down is likely to occur, and the proxy server automatically migrates one or more target virtual machines operated by the overload cluster server to an idle cluster server with sufficient current resources, so that the cluster server in the automatic migration system of the virtual machine is in a stable operation state, the workload of operation and maintenance personnel is saved, the migration efficiency is high, and the user experience is improved.
The technical scheme provided by the present disclosure is described in detail below with specific examples.
Referring to fig. 3, fig. 3 is a flowchart of an automatic migration method of a virtual machine according to an embodiment of the present disclosure, where the automatic migration method of a virtual machine provided by the embodiment is executed by a server, and the server may be a proxy server in the automatic migration system of a virtual machine shown in fig. 2. The method provided by the embodiment may include the following steps.
Step 301, obtaining state information of each cluster server.
The state information of the cluster server is used for indicating the current resource occupation condition of the cluster server.
Alternatively, the status information of the cluster server may include, but is not limited to: processing at least one of resource consumption information, memory resource usage information, network resource occupation information, and input/output resource occupation information.
The proxy server can acquire the state information of the cluster server by sending a query message to the cluster server; the cluster server can also send the state information of the cluster server to the proxy server periodically or in real time in an active reporting mode.
Step 302, determining an overload cluster server from the cluster servers according to the state information of the cluster servers and the resource information of the cluster servers.
The resource information of the cluster server refers to the total amount of each resource of the cluster server.
Alternatively, the resource information of the cluster server may include, but is not limited to: at least one of a total amount of processing resources, a total amount of memory resources, a total amount of network resources, and a total amount of input/output resources.
The overload cluster server refers to overload of a currently running virtual machine, that is, the current resource occupation exceeds the amount that the cluster server can bear. The virtual machines running in the overloaded cluster server may get stuck and even down.
For each cluster server, the proxy server can judge whether the cluster server is overloaded according to the state information of the cluster server and the resource information of the cluster server, and if the cluster server is overloaded, the cluster server is determined to be the overloaded cluster server.
And 303, migrating the target virtual machine running in the overload cluster server to an idle cluster server.
The idle cluster server refers to that the resource occupation of the running virtual machine does not reach a saturated state, i.e. idle resources exist in the idle cluster server.
Wherein the target virtual machine is one or more virtual machines in the overloaded cluster server.
For each overloaded cluster server, the proxy server migrates the target virtual machine running in that overloaded cluster server to any of the idle cluster servers to transition that overloaded cluster server to a non-overloaded state.
According to the automatic migration method of the virtual machine, the proxy server can acquire the state information of the cluster server in the automatic migration system of the virtual machine in real time, and according to the state information and the resource information of the cluster server, whether the overload cluster server operated by overload exists currently or not is determined, the situation that the virtual machine operated by the overload cluster server is blocked or even down is likely to occur, and the proxy server automatically migrates one or more target virtual machines operated by the overload cluster server to an idle cluster server with sufficient current resources, so that the cluster server in the automatic migration system of the virtual machine is in a stable operation state, the workload of operation and maintenance personnel is saved, the migration efficiency is high, and the user experience is improved.
Further, step 302 may be implemented by the following step 3021, based on the embodiment shown in fig. 3.
And 3021, obtaining the resource occupation ratio of each cluster server according to the state information of each cluster server and the resource information of each cluster server.
In this embodiment, if the status information of the cluster server includes one type of information, the proportion of the status information to the resource information is the resource occupation proportion
If the state information of the cluster server contains two or more kinds of information, each kind of state information can be together with the corresponding resource information to determine the resource occupation proportion. Illustratively, when the state information includes processing resource consumption information and the resource information includes a total amount of processing resources, the ratio value of the processing resource consumption information to the total amount of processing resources is a processing resource occupation ratio.
Step 3022, judging whether the resource occupation ratio of each cluster server is greater than or equal to a saturation threshold.
If yes, go on to step 3023. If not, then step 3024 is continued.
The saturation threshold may be used to indicate that the proportion of occupied resources is beyond the range that the current cluster server can carry.
The saturation threshold may be preset, or may be determined according to the obtained smoothness of the virtual machine running in each cluster server and the resource occupation ratio of each cluster server. The smoothness of the virtual machines running in the cluster server may be obtained according to information fed back by the user using the virtual machines.
Correspondingly, if the state information of the cluster server contains one kind of information, judging whether the resource occupation proportion is larger than or equal to a saturation threshold.
If the state information of the cluster server contains two or more kinds of information, when judging whether the resource occupation proportion is greater than or equal to the saturation threshold, different kinds of resources can be respectively judged, namely, the resource occupation proportion determined by each kind of state information is compared and judged with the saturation threshold corresponding to the information. If the resource occupation proportion of any kind of information is larger than or equal to the saturation threshold of the kind, determining that the resource occupation proportion of the target cluster server is larger than or equal to the saturation threshold.
Illustratively, when the state information includes processing resource consumption information and the resource information includes a total amount of processing resources, it is required to determine whether the ratio of occupied processing resources is greater than or equal to a processing resource saturation threshold. If the current processing resource occupation ratio is greater than or equal to the processing resource saturation threshold, whether the occupation ratio of other kinds of resources is greater than or equal to the kind of resource saturation threshold or not can be determined that the occupation ratio of the resources of the target cluster server is greater than or equal to the saturation threshold.
And 3023, determining the cluster server as a target cluster server, and taking the target cluster server as an overload cluster server.
Step 3024, determining that the cluster server is not an overloaded cluster server.
According to the embodiment, whether the target cluster server is overloaded is determined by comparing the resource occupation proportion of the cluster server with the saturation threshold, and the overloaded cluster server can be accurately and quickly determined, so that the overloaded cluster server is accurately and quickly processed. Therefore, the cluster server in the automatic migration system of the virtual machine is in a stable running state, the workload of operation and maintenance personnel is saved, the migration efficiency is higher, and the user experience is improved.
In some scenarios, the proxy server may maintain in real time which of the current cluster servers are idle cluster servers and saturated cluster servers, so that when the overload cluster server needs to be processed, virtual machines running in the overload cluster server are moved to the idle cluster server in time. Specific examples are described in detail below.
Further, step 3030 may be included prior to step 303 on the basis of any of the method embodiments described above.
Step 3030, determining an idle cluster server and a saturated cluster server according to the state information of each cluster server and the resource information of each cluster server.
The free cluster server refers to a cluster server that has free resources currently available and can be used for a newly built virtual machine without causing virtual machine blocking.
The saturated cluster server refers to a cluster server which has few free resources at present and is provided for a newly built virtual machine to use, so that the virtual machine is blocked and the like.
Further, step 3030 may be implemented by the following steps.
Step 30301, determining the cluster server with the unassigned resource as an initial idle cluster server according to the status information of each cluster server and the resource information of each cluster server, and determining the cluster server without the unassigned resource as an initial saturated cluster server.
The cluster servers are divided into an initial idle cluster server and an initial saturated cluster server according to whether unallocated resources exist.
Step 30302, judging whether the resource occupation ratio exceeds the saturation threshold after the virtual machine is added to the initial idle cluster server.
If yes, go on to step 30303. If not, proceed to step 30304.
There are various implementations of the determination process in step 30302, and two implementations are shown below by way of example.
In one possible implementation, the determination may be based on resources occupied by a single virtual machine and resources already occupied by an initial idle cluster server.
In another possible implementation, the determination may be made by simulating an newly added service virtual machine to test whether the initial idle cluster server will reach a resource bottleneck.
Step 30303, updating the initial idle cluster server to a saturated cluster server to obtain the idle cluster server and the saturated cluster server.
And 30304, the initial idle cluster server is used as an idle cluster server to obtain an idle cluster server and a saturated cluster server.
In this embodiment, the initial idle cluster server may have few idle resources and cannot support the running of the newly added virtual machine, so that the initial idle cluster server needs to be updated to a saturated cluster server. The other initial idle cluster servers are idle cluster servers. Therefore, the idle cluster server is accurately and clearly determined, and migration processing is accurately carried out on the target virtual machine running in the overload cluster server. Therefore, the cluster server in the automatic migration system of the virtual machine is in a stable running state, the workload of operation and maintenance personnel is saved, the migration efficiency is higher, and the user experience is improved.
On the basis of any of the above method embodiments, further, step 303 may be implemented by the following steps.
Step 3031, judging whether the overload cluster server and the idle cluster server adopt shared disks to store virtual machine files.
If yes, go on to step 3032. If not, then step 3033 is continued.
Step 3032, migrating the service state information of the target virtual machine running in the overload cluster server to the idle cluster server.
Step 3033, judging whether the target virtual machine in the related power-on state is operated in the overload cluster server.
If yes, go on to step 3034. If not, then step 3035 is continued.
And step 3034, migrating the target virtual machine running in the overload cluster server to an idle cluster server.
And step 3035, migrating the target virtual machine running in the overload cluster server to an idle cluster server after the target virtual machine is powered off.
In this embodiment, if the overload cluster server and the idle cluster server adopt the shared disk to store the virtual machine files, the live migration may be performed, that is, the virtual machine files stored in the shared disk may not be moved, and the service state information may be migrated. If the overload cluster server and the idle cluster server do not adopt the shared disk to store virtual machine files, cold migration can be performed, because the virtual machines needing to be migrated are interrupted by the cold migration, whether the virtual machines in the shutdown state exist in operation can be checked in the overload cluster server to reduce the influence on the operation of the virtual machines, if so, the virtual machines in the shutdown state can be directly migrated, and if not, one or more target virtual machines in the virtual machines need to be shutdown first and then the migration operation is performed.
The method provided by the present disclosure is described below with specific examples. The present example includes the following processing steps.
Step 1, a Broker server queries information and a state of a host, where the information includes, but is not limited to, hardware configuration (parameters such as cpu, memory, etc.) of the host, and the state is a current state (parameters such as cpu, memory, network, IOPS, etc. in the running process) of the host.
And step 2, detecting whether a certain parameter in the current running state of the host reaches the bottleneck or a performance alarm appears.
And step 3, executing migration operation.
Each step is described in detail below. Step 1 may include the following steps 1.1 to 1.5. Step 2 may include the following steps 2.1 and 2.2. Step 3 may include the following steps 3.1 and 3.2.
And 1.1, the proxy server monitors the environment information and the state of all the nodes, and the specific implementation can be that the proxy server inquires or automatically reports the nodes.
Step 1.2, the obtained node information comprises information such as the number of allocated physical cpus, the memory size and the like, and according to the information, the number of virtual machines supported by the current node on physical configuration can be judged.
Step 1.3, the obtained node state comprises the current running state, such as occupation conditions of cpu, memory, network and the like, and whether the node resource reaches the bottleneck state can be judged according to the parameters; specifically, whether the occupancy rate of the parameters reaches more than 90% or not can be judged, or the feedback fluency and the resource occupancy condition of the clients can be collected according to big data, and the resource bottleneck is calculated, if the current resource usage exceeds the bottleneck, the migration work can be judged to be needed, or the migration work can be started manually according to the feedback of the clients; the above policy implementations can be designed in detail by the architect according to the specific scenario, this time providing only a few options. Note that since each parameter affects the overall usage, migration is required when one parameter exceeds the bottleneck.
And 1.4, sorting the node information collected in the step 1.2, and dividing the node information into an a form and a b form, wherein the a form is a node list which is supported by physical configuration and is used for continuously establishing virtual machine resources, and the b form is a node list which is not supported by physical configuration and is used for continuously establishing the virtual machine resources (which can be judged according to the existing unassigned resources).
Step 1.5, optimizing the two forms a and b in the step 1.4, wherein the optimizing point is a node which is selected from the form a and has a new virtual machine exceeding the resource bottleneck, and then removing the node from the form a and adding the node into the form b; the method is specifically realized, the judgment can be carried out according to the occupied resources of a single virtual machine and the occupied resources of the nodes in the form a, or whether the nodes can reach the resource bottleneck can be tested by simulating the newly added service virtual machine; note here that the newly added node defaults to form a and the newly added virtual machine resource defaults to be added on the node in form a.
Step 2.1, triggering a resource bottleneck or giving a performance alarm when a user uses a cloud desktop; specific strategies may refer to the proposed strategy implementation scheme in step 1.3.
And 2.2, automatically triggering the migration operation, or manually starting the automatic migration operation by operation and maintenance personnel due to insufficient customer feedback performance resources.
Step 3.1, according to the processing scheme in step 1.5, the migration process is that the nodes in the form b migrate to the nodes in the form a, and an automatic migration scheme can be automatically judged and set according to the strategy, specifically, the migration action is automatically completed by the system, and the resource judgment is completed by the scheme in step 1.5; if the current virtualization scheme is a shared disk, a thermomigration scheme can be used, virtual machines on the nodes can use shared storage to store virtual machine files, so that the time for copying hard disks is saved, the current service state information, including upper-layer connection table items such as memory and TCP and the like, is only transferred between two nodes, the copying time of state synchronization is relatively short, and the original virtual machine can also provide services when in synchronization so that the service can not be interrupted; if the current virtualization scheme does not adopt a shared disk, cold migration is needed, and the cold migration needs to perform shutdown and re-migration on the virtual machine, which can cause user service interruption, and it is recommended that the virtual machine with other states on the node as shutdown can be migrated.
Step 3.2, reclassifying the two migrated nodes according to step 1.5, but note that the node migrating the virtual machine needs to judge whether to add the form b according to the actual situation, if the virtual machine with smaller calculation amount is required, the virtual machine resource can be continuously added on the node, and if the scene is not available, the virtual machine resource can be directly added into the form b.
