Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

FIG. 1 is a flow chart of Embodiment 1 of the virtual machine creation method of the present invention. As shown in Figure 1, the method includes the following steps:

101. The management node receives a first virtual machine creation instruction issued by a cloud management platform, where the first virtual machine creation instruction is used to instruct creation of at least one virtual machine.

In this embodiment, the user accesses the cloud management platform through a personal computer (PC for short), and the user initiates a request to the cloud management platform to create multiple virtual machines. In the request message initiated to the cloud management platform, the user can Specify to create a virtual machine on a certain host, or not to specify a host. When the user specifies to create a virtual machine on a certain host, the cloud management platform will send a first virtual machine creation instruction to the management node that manages the host.

In this embodiment, the user does not designate a host to create a virtual machine as an example for illustration. When the cloud management platform receives a user's request to create a virtual machine, it may issue a first virtual machine creation instruction to the management node.

Specifically, the first virtual machine creation instruction issued by the cloud management platform to the management node may be used to indicate the creation of at least one virtual machine, that is, may be used to indicate the number of virtual machines to be created, and may also be used to indicate the operation of creating a virtual machine type. Optionally, the first virtual machine creation instruction is used to indicate any one or a combination of the following virtual machine creation operations: linking a virtual machine, copying a virtual machine, starting a virtual machine, migrating a virtual machine, waking a virtual machine, restarting a virtual machine machine.

In the above operation of creating a virtual machine, a linked clone virtual machine means that multiple virtual machines have only one system volume (parent volume), while for ordinary virtual machines, each virtual machine has a system volume, that is, one system volume can be virtual machines at the same time. Virtual machine replication refers to completely copying an already created virtual machine to obtain another virtual machine, through which multiple identical virtual machines can be copied. Virtual machine migration refers to moving a virtual machine from one host to another without affecting the user's business during the move. Virtual machine wake-up means that the virtual machine restarts after hibernation, and the user can continue the operation performed before hibernation after startup. Rebooting a virtual machine means restarting the virtual machine. Virtual machine startup means that the virtual machine is turned off and powered on again. Restarting a virtual machine means recreating a new virtual machine. The above various operations for creating a virtual machine are all existing technologies, and will not be described in detail here.

102. The management node determines to create a virtual machine on at least one host according to the first virtual machine creation instruction and resource utilization information of managed hosts.

The management node is the service entrance, capable of receiving virtual machine creation commands issued by the cloud management platform, parsing the creation commands, and instructing the managed hosts to perform corresponding creation operations. The management node can manage multiple hosts, instruct the hosts to create virtual machines, monitor the resource usage of each host, etc.

After the management node receives the creation instruction of the first virtual machine, it may analyze resource utilization of each managed host. Optionally, the resource utilization information of the host may include any one or a combination of the following information: idle resource information of the host, CPU utilization information of the central processing unit of the host, memory utilization information of the host, network traffic information of the host . The idle resource information of the host includes remaining CPU and memory. The management node may periodically or aperiodically obtain resource information of each host managed by the management node, or each host may actively report its own resource information to the management node periodically or aperiodically.

The management node may determine to create a virtual machine on at least one host according to the number of created virtual machines determined by the first virtual machine creation indication, the type of creation operation, and the resource utilization information of each managed host. Specifically, the management node may determine a busy host and an idle host according to the acquired resource information of each host. For example: the management node can determine the busy host and the idle host according to the CPU utilization rate, the host whose CPU utilization rate is greater than or equal to a certain value can be determined as a busy host, and the host whose CPU utilization rate is lower than the value can be determined as As an idle host, the management node may select at least one idle host from the determined idle hosts to create a virtual machine. For a busy host, the management node may not issue a virtual machine creation instruction to the host. The above is only an example of determining the idle host and the busy host based on the CPU utilization. It is understandable that the busy host and the idle host can also be determined according to other resource information of the host, such as memory utilization, current network traffic information , or a combination of the above-mentioned various resource utilization information is determined, and is not limited thereto.

103. The management node delivers a second virtual machine creation instruction to the determined at least one host, where the second virtual machine creation instruction is used to instruct creation of at least one virtual machine.

Wherein, the second virtual machine creation instruction may be used to indicate any one or a combination of the following virtual machine creation operations: linking a virtual machine, copying a virtual machine, starting a virtual machine, migrating a virtual machine, waking up a virtual machine, restarting a virtual machine .

After the host receives the second virtual machine creation instruction issued by the management node, it may execute a corresponding virtual machine creation operation according to the creation instruction.

In this embodiment, the management node instructs at least one host to create a virtual machine according to the received virtual machine creation instruction issued by the cloud management platform and resource utilization conditions of each managed host. The management node can dynamically assign the task of creating a virtual machine to each host according to the resource utilization of each host, so as to achieve a reasonable allocation of network resources and improve the utilization rate of the entire network.

FIG. 2 is a flow chart of Embodiment 2 of the virtual machine creation method of the present invention. The method specifically includes the following steps:

201. The host receives a second virtual machine creation instruction delivered by a management node, where the second virtual machine creation instruction is used to instruct creation of at least one virtual machine.

Optionally, the second virtual machine creation instruction may be used to indicate any one or a combination of the following virtual machine creation operations: linking a virtual machine, copying a virtual machine, starting a virtual machine, migrating a virtual machine, waking up a virtual machine, restarting virtual machine.

In this embodiment, the host is determined by the management node according to the first virtual machine creation instruction issued by the cloud management platform and the resource utilization information of each managed host. For the specific determination process, refer to the relevant description in Embodiment 1. , which will not be repeated here.

202. The host correspondingly creates a virtual machine on the host according to the second virtual machine creation instruction.

In this embodiment, rebuilding a new virtual machine is taken as an example to describe the operation of creating a virtual machine performed by the host. The host receives the second virtual machine creation instruction, and the second virtual machine creation instruction rebuilds a new virtual machine. The host can first create a virtual machine through low-level commands that require disks, network cards, etc., and copy the operating system OS (Operate System, referred to as OS). Peripheral devices, including serial ports, optical drives, etc., after the software and hardware resources required by the virtual machine are created, finally call the Hypervisor (Hypervisor is a "meta" operating system in a virtual environment) to access the host, including disks and All physical devices including memory. Hypervisors not only coordinate access to these hardware resources. When the host starts and executes the hypervisor, it loads the operating system of all virtual machine clients and allocates the appropriate amount of memory, CPU, network and disk to each virtual machine. It should be noted that when creating a virtual machine, the disk of the virtual machine can be a local disk of the host, or various storage devices connected to the host, such as: network-based storage device IPSAN, fiber-based storage device FCSAN, etc.

FIG. 3 is a schematic structural diagram of a host server. As shown in Figure 3, the host hardware resources also include CPU, memory, Nic, and disk. There are multiple virtual machine VMs running on the host, and the Hypervisor supports the operation of the virtual machines. When the virtual machine is running, the Hypervisor calls the virtual central processing unit (VirtualCentral Processing Unit, VCPU for short), virtual memory management unit (Virtual Memory Management Unit, VMMU for short), and event channel (Event Channel) and other virtual resources on the host. The Hypervisor is invoked through the libvirt process to ensure the operation of the virtual machine. When the virtual machine is running, the Virtual Node Agent (VNA for short) module is mainly used to monitor the resource usage information of the host itself in real time. libvirt is a set of free and open source C function libraries that support mainstream virtualization tools, and aims to provide a set of convenient and reliable programming interfaces for various virtualization tools. The Qemu module is mainly used to monitor the processes of each virtual machine on the host. The OM is mainly used to manage the daily maintenance operations of the network, including monitoring the hardware resources of the host and sending alarm information. The watchdog is mainly used to monitor the running status of each process on the host.

On the other hand, the host monitors the resource usage information of the host itself while performing the operation of creating a virtual machine, which may specifically include any one or a combination of the following information: the current CPU utilization, memory, and network traffic of the host, according to the above resources Use the information to determine the free resources currently available from the host. The monitoring function can be completed by the VNA module in the host, and the VNA is mainly used to monitor the resource usage information of the host itself in real time. The VNA can report the monitored resource usage information to the management node. Specifically, it can be reported to the VRM on the management node. The management node can determine idle hosts and busy hosts according to the resource information of the hosts, so that at least one idle host can be determined for virtualization. machine-created operations.

In this embodiment, the host monitors its own resource utilization information in real time when creating a virtual machine, and the management node dynamically assigns the task of creating a virtual machine to each host according to the resource utilization of the host, so that the resources of each host can be obtained. Reasonable and adequate use. Improve resource utilization across the network.

Fig. 4 is a flow chart of Embodiment 3 of the method for creating a virtual machine provided by the present invention. As shown in Fig. 4, the method includes the following steps:

401. The user initiates a virtual machine creation request to the cloud management platform.

In this step, the user can access the cloud management platform through a PC, and the user initiates a virtual machine creation request to the cloud management platform, and requests to create multiple virtual machines. Create a virtual machine on the host, and you can't specify the host. When the user specifies to create a virtual machine on a certain host, the cloud management platform will send a first virtual machine creation instruction to the management node that manages the host.

402. The cloud management platform delivers a first virtual machine creation instruction to the management node, where the first virtual machine creation instruction is used to instruct creation of at least one virtual machine.

The cloud management platform manages and controls the entire network resources. Specifically, the first virtual machine creation instruction issued by the cloud management platform to the management node may be used to indicate the creation of at least one virtual machine, that is, may be used to indicate the number of virtual machines to be created, and may also be used to indicate the operation of creating a virtual machine type. Optionally, the first virtual machine creation instruction is used to indicate any one or a combination of the following virtual machine creation operations: linking a virtual machine, copying a virtual machine, starting a virtual machine, migrating a virtual machine, waking a virtual machine, restarting a virtual machine machine.

403. The management node receives the first virtual machine creation instruction issued by the cloud management platform, and the management node determines to create a virtual machine on at least one host according to the first virtual machine creation instruction and resource utilization information of each managed host.

The management node is the service entrance, capable of receiving virtual machine creation commands issued by the cloud management platform, parsing the creation commands, and instructing the managed hosts to perform corresponding creation operations. The management node can manage multiple hosts, instruct the hosts to create virtual machines, monitor the resource usage of each host, and so on. The management node may be a server, and FIG. 5 is a structural diagram of the management node server. As shown in the figure, the management node server is mainly composed of software, OS and hardware. The hardware part includes CPU, memory, network interface card (NIC for short) and disk. The OS includes a virtual resource management (virtual resource management, referred to as VRM) module, an operation and maintenance (Operation Maintenance, referred to as OM) center, and a watchdog. VRM is mainly used to control the resource utilization of each host managed by the management node and the virtualized resources in the network; the watchdog is used to monitor the running status of each process in the host; OM is mainly used to manage the daily maintenance operations of the network .

After the management node receives the creation instruction of the first virtual machine, it may analyze resource utilization of each managed host. Optionally, the resource utilization information of the host may include any one or a combination of the following information: idle resource information of the host, CPU utilization information of the central processing unit of the host, memory utilization information of the host, network traffic information of the host . The management node may periodically or aperiodically obtain resource information of each host managed by the management node, or each host may actively report its own resource information to the management node periodically or aperiodically. Specifically, it can be completed by the VRM on the host. The VRM can periodically broadcast messages to each host managed by the management node. The message is used to obtain the resource information of each host. After receiving the broadcast message, each host sends the message to the management The node returns a response, which carries the resource information of the host, for example: the above-mentioned host's current idle resource information, the host's central processing unit CPU utilization information, the host's memory utilization information, and the host's network traffic information etc.

The management node may determine to create a virtual machine on at least one host according to the number of created virtual machines determined by the first virtual machine creation indication, the type of creation operation, and the resource utilization information of each managed host. Specifically, the management node may determine a busy host and an idle host according to the acquired resource information of each host. The management node may select at least one idle host from the determined idle hosts to create a virtual machine. For a busy host, the management node may not issue a virtual machine creation instruction to the host.

Since the host resources occupied by each virtual machine creation operation are different, optionally, the management node can set corresponding weights for different virtual machine creation operations according to the host resources occupied by different virtual machine creation operations, for example: A relatively high weight value can be set for a creation operation that occupies relatively high host resources, and a relatively low weight value can be set for a creation operation that occupies low host resources. On the other hand, the management node can execute the operation with a higher weight value on the host with a relatively higher idle rate among the selected hosts according to the idle resources provided by each host and the weight value set for each virtual machine creation operation. Create a virtual machine operation, and execute a virtual machine creation operation with a lower weight value on a host with a relatively low idle rate. The management node can monitor the resource usage of each host in real time. The resource idleness of each host may change due to the creation of a virtual machine. For example, when a host with high idle resources executes the corresponding creation of a virtual machine reduce. Therefore, the management node can re-determine the busy host and the idle host periodically or aperiodically, so as to make reasonable use of the resources provided by each host.

404. The management node delivers a second virtual machine creation instruction to the determined at least one host, where the second virtual machine creation instruction is used to instruct creation of at least one virtual machine.

Wherein, the second virtual machine creation instruction may be used to indicate any one or a combination of the following virtual machine creation operations: linking a virtual machine, copying a virtual machine, starting a virtual machine, migrating a virtual machine, waking up a virtual machine, restarting a virtual machine .

405. The host receives the second virtual machine creation instruction delivered by the management node, and correspondingly creates a virtual machine on the host according to the second virtual machine creation instruction.

In this step, after the host receives the second virtual machine creation instruction issued by the management node, it can execute a corresponding virtual machine creation operation according to the creation instruction. Specifically, the host performs the following virtual machine creation operations according to the creation instruction of the second virtual machine: linking the virtual machine, copying the virtual machine, starting the virtual machine, migrating the virtual machine, waking up the virtual machine, and restarting the virtual machine.

On the other hand, the host monitors the resource usage information of the host itself while performing the operation of creating a virtual machine, which may specifically include any one or a combination of the following information: the current CPU utilization, memory, and network traffic of the host, according to the above resources Use the information to determine the free resources currently available from the host. The monitoring function can be completed by the VNA module, and the VNA is mainly used to monitor the resource usage information of the host itself in real time. The VNA can report the monitored resource usage information to the management node. Specifically, it can be reported to the VRM on the management node. The management node can determine idle hosts and busy hosts according to the resource information of the hosts, so that at least one idle host can be determined for virtualization. machine-created operations.

VNA is used to monitor the resource information of the host itself in real time. After the host performs a virtual machine creation operation, the resources of the host may change accordingly. The VNA can report the resource information of the host to VRM in real time, so that VRM can accurately determine the idle host. And busy hosts, reasonable allocation of network resources. In this embodiment, each operation of creating a virtual machine occupies different resources. Therefore, the management node can assign different weight values to each operation of creating a virtual machine. For example, the resource occupied when copying a virtual machine can be 100%. Link The resources occupied by the cloned virtual machine can be 25%, the resources occupied by the started virtual machine can be 30%, the resources occupied by the migrated virtual machine can be 20%, and the resources occupied by the awakened virtual machine can be 50%. For example, the current idle resource of the host is 100%. When VRM starts a virtual machine on the host, the idle resource of the host is reduced from 100% to 70%. If another virtual machine is migrated on the host, the idle resource of the host is reduced. 50%. VRM can increase or decrease the operation of creating virtual machines according to the resource conditions monitored by VNA. When the resources available from the host are high, the speed of creating virtual machines can be increased. When the resources available from the host are low, VRM will choose other options. Hosts with high resources create virtual machines. Specifically, for example, VRM selects three hosts for virtual machine creation. Suppose VNA1 monitors that the idle resources of host A are 90%, VNA2 monitors that host B’s idle resources are 80%, and VNA3 monitors that host C’s idle resources are 60%. %, then VRM first migrates a virtual machine on host A, and the resources occupied by the migrated virtual machine are 20%, and after the virtual machine is migrated, the resources of host A are reduced to 70%. At this time, the resources of host A are lower than those of host B. , then VRM will preferentially select host B for virtual machine creation during the next virtual machine creation operation. In this way, VRM can select hosts with high idle resources to create virtual machines based on the resource usage information of hosts monitored by each VNA, which not only improves the speed of creating virtual machines, but also does not affect other user services.

In the method for creating a virtual machine provided in this embodiment, the management node instructs at least one host to create a virtual machine according to the received virtual machine creation instruction issued by the cloud management platform and the resource utilization of each managed host. The host executes an operation of creating a virtual machine according to the received second virtual machine creation instruction delivered by the management node and simultaneously monitors its own resource utilization. The management node can dynamically assign the task of creating a virtual machine to each host according to the resource utilization of each host, so as to achieve a reasonable allocation of network resources and improve the utilization rate of the entire network.
