[0048] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] The method for constructing a virtual machine provided in an embodiment of the present application can be applied to an application environment as shown in Figure 1. Wherein, the computer device can be a server, and its internal structure diagram can be shown in Figure 1. The computer device includes a processor, a memory, an input / output interface (Input / Output, referred to as I / O) and a communication interface.

The database of the computer device is used to store the construction data of the virtual machine. The input / output interface of the computer device is used to exchange information between the processor and an external device. The communication interface of the computer device is used to communicate with an external terminal through a network connection. When the computer program is executed by the processor, a method for constructing a virtual machine is implemented.

[0050] Those skilled in the art will understand that the structure shown in FIG. 1 is merely a block diagram of a partial structure related to the solution of the present application, and does not constitute a limitation on the computer device to which the solution of the present application is applied. The specific computer device may include more or fewer components than shown in the figure, or combine certain components, or have a different arrangement of components.

[0051] In one embodiment, as shown in FIG. 2 , a method for constructing a virtual machine is provided, and the method is applied to the server in FIG. 1 as an example for explanation, including:

[0052] S201, determining a corresponding construction strategy according to construction requirements of a target virtual machine to be constructed.

[0053] The construction requirement may include the type of the target virtual machine; or the construction requirement may include the type and configuration parameters of the target virtual machine. The type of virtual machine includes a performance-based virtual machine and a bandwidth-based virtual machine.

[0054] In an embodiment of the present application, the server can pre-form a policy library with multiple construction strategies and store the correspondence between each construction requirement and the construction strategy, so as to determine the rated construction strategy corresponding to the construction requirement of the target virtual machine from the policy library based on the construction requirements and the correspondence of the target virtual machine.

[0055] S202: Build a target virtual machine on a target node of a physical machine according to configuration parameters and a build strategy of the target virtual machine.

[0056] The configuration parameters of the target virtual machine may include at least one of the number of virtual sockets, the number of virtual processor blocks in each virtual socket, the number of virtual cores in each virtual processor block, and the number of virtual threads in each virtual core, wherein the virtual socket may be represented as vSocket, the virtual processor block in each virtual socket may be represented as vDIES, the virtual core in each virtual processor block may be represented as vCores, and the virtual thread in each virtual core may be represented as vThreads; or, the configuration parameters of the target virtual machine may include the number of virtual threads, and the virtual thread may be represented as vCPU. The target node may be a node on a physical machine under a non-uniform memory access (NUMA) architecture.

[0057] In an embodiment of the present application, the server itself is a physical machine, and a virtual machine can be built in a physical node of the physical machine. The server can parse the build requirements to obtain the configuration parameters of the target virtual machine; or, the server can determine the default configuration parameters from a preset database; or, the server can parse the build requirements to determine at least one of the number of vSockets, the number of vDIES, the number of vCores, and the number of vThreads of the target virtual machine, and determine the remaining configuration parameters that are not in the build requirements from a preset database. Furthermore, according to the configuration parameters and build strategy of the target virtual machine, a preset build script can be run to build the target virtual machine on the target node of the physical machine.

[0058] Optionally, when the configuration parameters include the number of vSockets, the number of vDIES, the number of vCores, and the number of vThreads, the product of the number of vSockets, the number of vDIES, the number of vCores, and the number of vThreads may be determined as the number of vCPUs, thereby building the target virtual machine on the target node of the physical machine according to the number of vCPUs and the building strategy. When the configuration parameters include the number of vCPUs, the target virtual machine is built on the target node of the physical machine according to the number of vCPUs and the building strategy.

[0059] In the above-mentioned virtual machine construction method, the corresponding construction strategy is determined according to the construction requirements of the target virtual machine to be constructed; thus, the target virtual machine is constructed on the target node of the physical machine according to the configuration parameters and construction strategy of the target virtual machine. According to the construction requirements of the target virtual machine, the construction strategy is determined so that the constructed target virtual machine is more matched with the actual use requirements, so that the target virtual machine can exert better performance in actual use. At the same time, according to the configuration parameters and construction strategy of the target virtual machine, the matching degree between the target virtual machine and the actual use requirements is further improved, thereby further improving the performance of the target virtual machine.

[0060] In one embodiment, an implementation of the above S201 is provided, as shown in FIG3 , wherein the above “determining a corresponding construction strategy according to the construction requirements of the target virtual machine to be constructed” includes:

[0061] S301, determine whether the construction requirement is the construction requirement of a performance-type virtual machine or the construction requirement of a bandwidth-type virtual machine. If the construction requirement is the construction requirement of a performance-type virtual machine, execute S302; if the construction requirement is the construction requirement of a bandwidth-type virtual machine, execute S303.

[0062] The construction requirements of the target virtual machine include the construction requirements of a performance-type virtual machine or a bandwidth-type virtual machine. A performance-type virtual machine can provide powerful central processing unit (CPU) computing power to meet workloads with high computing requirements. It is suitable for application scenarios that require a large amount of computing resources, such as scientific computing, big data analysis, and complex engineering simulations. A bandwidth-type virtual machine is a high-memory bandwidth virtual machine that can provide high memory bandwidth and a large amount of random access memory (RAM) to support memory-intensive workloads. It is suitable for large databases, memory caches, and real-time big data analysis.

[0063] In the embodiment of the present application, the first construction strategy and the second construction strategy are pre-stored in the server, so as to match the corresponding construction strategy for the target virtual machine according to the construction requirements.

[0064] S302, determining that the construction strategy is a first construction strategy; the first construction strategy includes building a target virtual machine on a centralized node on a physical machine.

[0065] In an embodiment of the present application, the first construction strategy includes constructing a target virtual machine on a centralized node on a physical machine, wherein the centralized node is a node or a plurality of consecutive nodes on the physical machine. Since performance-oriented virtual machines require powerful CPU computing power, virtual machines established on centralized nodes can perform operations such as computing and processing in a centralized manner in the memory corresponding to the centralized node, so the first construction strategy is determined as the construction strategy corresponding to the performance-oriented virtual machine.

[0066] S303, determining that the construction strategy is a second construction strategy; the second construction strategy includes constructing a target virtual machine on nodes dispersed on the physical machine.

[0067] In an embodiment of the present application, the second construction strategy includes constructing a target virtual machine on dispersed nodes on a physical machine, wherein the dispersed nodes are multiple nodes corresponding to one slot on the physical machine, or multiple nodes corresponding to multiple slots on the physical machine. Since a bandwidth-type virtual machine can provide high memory bandwidth, when constructing a target virtual machine on dispersed nodes, the target virtual machine can simultaneously access the memory corresponding to multiple nodes, so the second construction strategy is determined as the construction strategy corresponding to the bandwidth-type virtual machine.

[0068] In the above application embodiment, when the construction requirement is a construction requirement for a performance-type virtual machine, the construction strategy is determined to be the first construction strategy, and when the construction requirement is a construction requirement for a bandwidth-type virtual machine, the construction strategy is determined to be the second construction strategy, which improves the matching degree between the construction requirement and the construction strategy, thereby improving the matching degree between the target virtual machine and the application scenario, so that the target virtual machine can perform better performance during use.

[0069] In one embodiment, an implementation of the above S202 is provided, the construction strategy is a first construction strategy, as shown in FIG4 , and the above “constructing the target virtual machine on the target node of the physical machine according to the configuration parameters and construction strategy of the target virtual machine” includes:

[0070] S401, determining whether the number of virtual threads in the configuration parameters is less than the number of physical threads corresponding to each socket of the physical machine.

[0071] In an embodiment of the present application, it is determined whether the number of virtual threads in the configuration parameters is less than the number of physical threads corresponding to each slot of the physical machine. If not, the construction of the target virtual machine fails. If less, the server can continue to build the target virtual machine according to the first construction strategy.

[0072] For example, as shown in FIG5 , FIG5 includes two slots of a physical machine, namely slot 1 and slot 2, each slot includes two nodes, namely node 0, node 1, node 2 and node 2, each node includes 8 physical threads, that is, each slot of the physical machine includes 16 physical threads. If the number of virtual threads is 15, it is determined that the number of virtual threads is less than the number of physical threads.

[0073] S402, when the number of virtual threads is less than the number of physical threads, determine the target node according to the number of virtual threads and the number of physical threads, and allocate the virtual threads of the target virtual machine to the physical threads of the target node; the target node is a node or multiple consecutive nodes on the physical machine.

[0074] In the embodiment of the present application, when the number of virtual threads is less than the number of physical threads, it is determined whether the number of virtual threads is less than the number of physical threads corresponding to each node. If the number of virtual threads is less than the number of physical threads corresponding to each node, the number of target nodes is determined to be 1, and the target node is determined from multiple nodes of the physical machine according to the construction order of the target virtual machine. Further, a physical thread with the same number as the virtual thread is randomly selected from the target node, and the virtual threads of the target virtual machine are allocated to the physical threads of the target node in a one-to-one correspondence manner.

[0075] For example, if a total of 6 virtual machines are built, namely virtual machine 0, virtual machine 1, virtual machine 2, virtual machine 3, virtual machine 4, virtual machine 5 and virtual machine 6, and the physical machine includes 4 nodes, namely node 0, node 1, node 2 and node 3, then the target node of virtual machine 0 is node 0, the target node of virtual machine 1 is node 1, the target node of virtual machine 2 is node 2, the target node of virtual machine 3 is node 3, the target node of virtual machine 4 is node 0, and the target node of virtual machine 5 is node 1.

[0076] Exemplarily, if the number of virtual threads of a virtual machine is 4, the schematic diagram of the virtual threads of the target virtual machine at the target node can be as shown in Figure 5, where VM0, VM1, VM2, VM3, VM4, and VM5 in Figure 5 represent the virtual threads of virtual machine 0, virtual machine 1, virtual machine 2, virtual machine 3, virtual machine 4, and virtual machine 5, respectively.

[0077] In the embodiment of the present application, if the number of virtual threads is not less than the number of physical threads corresponding to each node, the number of virtual threads is divided by the number of physical threads corresponding to each node, and the ceiling function is constructed and rounded up to determine the number of target nodes, and multiple target nodes are determined from multiple nodes of the physical machine according to the construction order of the target virtual machine. Further, physical threads with the same number of virtual threads are randomly selected from the multiple target nodes, and the virtual threads of the target virtual machine are allocated to the physical threads of the target node in a one-to-one correspondence manner.

[0078] Exemplarily, if the number of virtual threads is 9 and the number of physical threads corresponding to each node is 8, then 8 is divided by 9 and a ceiling function is constructed to round up to determine the number of target nodes to be 2. Further, if a total of 4 virtual machines are constructed, namely virtual machine 0, virtual machine 1, virtual machine 2, and virtual machine 3, and the physical machine includes 4 nodes, namely node 0, node 1, node 2, and node 3, then the target nodes of virtual machine 0 are node 0 and node 1, the target nodes of virtual machine 1 are node 2 and node 3, the target nodes of virtual machine 2 are node 0 and node 1, and the target nodes of virtual machine 3 are node 2 and node 3.

[0079] It should be noted that one virtual thread corresponds to one physical thread, but one physical thread can correspond to multiple virtual threads.

[0080] In the above application embodiment, a performance-based virtual machine is constructed on the target node based on the number of virtual threads and the number of physical threads, thereby improving the centralization of the node where the performance-based virtual machine is located, thereby improving the performance of the performance-based virtual machine.

[0081] In one embodiment, an implementation of the above S202 is provided, the construction strategy is a second construction strategy, as shown in FIG6 , and the above “constructing the target virtual machine on the target node of the physical machine according to the configuration parameters and construction strategy of the target virtual machine” includes:

[0082] S501, determining a target slot corresponding to a target virtual machine according to the number of virtual threads in the configuration parameters and the number of physical threads corresponding to each slot of the physical machine.

[0083] In the embodiment of the present application, it is determined whether the number of virtual threads in the configuration parameters is less than the number of physical threads corresponding to each slot of the physical machine. If so, the number of target slots corresponding to the target virtual machine is determined to be 1; if not, the number of target slots is determined based on the number of virtual threads and the number of physical threads corresponding to each slot. Further, the corresponding number of target slots is determined in the physical machine based on the number of target slots.

[0084] Optionally, the number of virtual threads is divided by the number of physical threads corresponding to each slot, and a ceiling function is constructed to round up. For example, as shown in Figure 7, the number of physical threads corresponding to each slot is 16. If the number of virtual threads is 4, the number of target slots is determined to be 1; if the number of virtual threads is 18, 18 is divided by 16 and a ceiling function is constructed to round up to determine the number of target slots to be 2.

[0085] S502, evenly distribute the virtual threads of the target virtual machine to the physical threads of each node in the target slot.

[0086] In an embodiment of the present application, if the target slot is 1, the virtual threads of the target virtual machine are evenly distributed to each node in the target slot. For example, if the number of virtual threads is 5, namely virtual thread 0, virtual thread 1, virtual thread 2, virtual thread 3 and virtual thread 4, and the target slot includes 4 nodes, namely node 0, node 1, node 2 and node 3, then virtual thread 0 can be distributed to any physical thread in node 0, virtual thread 1 can be distributed to any physical thread in node 1, virtual thread 2 can be distributed to any physical thread in node 2, virtual thread 3 can be distributed to any physical thread in node 3, and virtual thread 4 can be distributed to any physical thread in node 0; if the number of virtual threads is 2, namely virtual thread 0 and virtual thread 1, and the target slot includes 4 nodes, namely node 0, node 1, node 2 and node 3, then virtual thread 0 can be distributed to any physical thread in node 0, and virtual thread 1 can be distributed to any physical thread in node 1.

[0087] Exemplarily, if the number of virtual threads of the target virtual machine is 18, the target virtual machine may be as shown in FIG. 7 , where the VM in FIG. 7 is the virtual thread of the target virtual machine.

[0088] In the embodiment of the present application, if there is one target slot, all nodes in the target slot are used as target nodes, and virtual threads are evenly distributed to the physical threads of each target node.

[0089] In the above application embodiment, a bandwidth-type virtual machine is constructed on the target node according to the number of virtual threads and the number of physical threads, thereby improving the bandwidth of the bandwidth-type virtual machine and thus improving the performance of the bandwidth-type virtual machine.

[0090] In one embodiment, as shown in FIG8 , the method for constructing the virtual machine further includes:

[0091] S203, dividing the memory on the physical machine into large pages for each node according to the hardware information of the node on the physical machine.

[0092] The hardware information of the node includes node information, the number of cores of each node, etc.

[0093] In an embodiment of the present application, the memory capacity corresponding to each node on the physical machine is determined, and the memory capacity corresponding to each node is divided. The number of large page memories corresponding to each node can be determined, and the total number of large page memories can be determined based on the number of large page memories corresponding to the node, and the number of large page memories corresponding to each node and the total number of large page memories are stored in a preset storage location.

[0094] Optionally, the correspondence between the hardware information of each node and the large page memory information can be pre-set. The large page memory information can include the memory capacity corresponding to each large page, etc., so as to determine the corresponding large page memory information based on the hardware information and the correspondence, and then divide the large page memory of each node on the physical machine according to the large page memory information.

[0095] S204, allocating corresponding large page memory to the target node after the target virtual machine is built.

[0096] In an embodiment of the present application, after the target virtual machine is built on the target node of the physical machine according to the configuration parameters and construction strategy of the target virtual machine, the pre-stored large page memory number corresponding to each node and the total large page memory number are written into the startup parameters of the target virtual machine, thereby allocating a corresponding number of large page memories to each node, so that the virtual thread can access the large page memory of the corresponding node.

[0097] In the above-mentioned application embodiment, the memory on the physical machine is divided into large page memory of each node, and the corresponding large page memory is allocated to the target node after the target virtual machine is built. The memory is allocated and managed through the large page memory, which improves the access speed and call speed of the target virtual machine to the memory, thereby improving the performance of the target virtual machine.

[0098] In one embodiment, an implementation of the above S203 is provided, as shown in FIG9 , wherein the above “dividing the memory on the physical machine into large pages of each node according to the hardware information of the node on the physical machine” includes:

[0099] S601, determining the memory requirement of the virtual machine on the node according to the memory requirement of the node on the physical machine and the preset allocation ratio; the preset allocation ratio represents the proportion of the memory allocated to the physical machine and the virtual machine on the node.

[0100] The memory requirement of the nodes on the physical machine is the memory capacity corresponding to each node.

[0101] In an embodiment of the present application, the product of the memory requirement of the node on the physical machine and the preset allocation ratio is used as the memory requirement of the virtual machine on the node, that is, the available memory of the virtual machine.

[0102] For example, if the memory requirement of the node is 512 GB and the preset allocation ratio is 90%, the memory requirement of the virtual machine on the node is 460.8 GB.

[0103] S602, determining the number of huge pages of the virtual machine on the node according to the memory requirement of the virtual machine on the node and the attribute information of the huge page memory.

[0104] The attribute information of the large page memory may include the content capacity corresponding to each large page.

[0105] In an embodiment of the present application, the ratio of the memory demand of the virtual machine on the node to the attribute information of the huge page memory is determined, and the integer part of the ratio is determined as the number of huge pages of the virtual machine on the node. For example, if the memory demand of the virtual machine on the node is 460.8G and the attribute information of the huge page memory is 2G, then the ratio of the memory demand of the virtual machine on the node to the attribute information of the huge page memory is 230.4G, and the number of huge pages of the virtual machine on the node is determined to be 230.

[0106] In the above-mentioned application embodiment, the number of large pages of the virtual machine on the node is determined based on the memory requirement of the node on the physical machine, the preset allocation ratio and the attribute information of the large page memory, so that the division of the large page memory is more accurate, and the memory requirement of the virtual machine on the node is determined based on the memory requirement of the node on the physical machine and the preset allocation ratio, so that the server can guarantee the memory requirements of both the physical machine and the virtual machine at the same time.

[0107] In one embodiment, a complete method for building a virtual machine is also provided, as shown in FIG10 , including:

[0108] S1, determining a corresponding construction strategy according to the construction requirements of the target virtual machine to be constructed.

[0109] S2, build the target virtual machine on the target node of the physical machine according to the configuration parameters and building strategy of the target virtual machine.
