Detailed Description
The technical solution of the present invention is further described in detail with reference to the drawings and the specific embodiments of the specification.
As shown in fig. 1, the present embodiment provides a virtual machine deployment method, including:
step S110: responding to request information created by a request virtual machine, and determining a currently available floating network protocol IP address;
step S120: when more than one physical network corresponding to the currently available floating IP address is available, acquiring a network state parameter of the physical network corresponding to the currently available floating IP address;
step S130: selecting a current available floating IP corresponding to the physical network which is most suitable for configuring the virtual machine at present as a target IP address according to the network state parameter;
step S140: and binding the target IP address and the created virtual machine.
The embodiment provides a virtual machine deployment method, which is applied to the deployment process of a virtual machine.
The floating IP address is a dynamically allocated IP address. The IP address where the floating IP address is located can realize the establishment of a corresponding relation with a physical network, or a plurality of floating IP addresses form a floating IP address section which establishes a corresponding relation with the physical network. For example, a floating IP address segment is assigned to a physical network.
The currently available floating IP address is a floating IP address that is currently in an unused state. In this embodiment, the network state parameter of the physical network corresponding to the currently available floating IP address is obtained, where the network state parameter is information reflecting the network state of the corresponding physical network. The network state may include a current load rate of the physical network, an available transfer rate, an available transfer bandwidth, and a configured number of virtual machines, a configurable maximum number of virtual machines. These network state parameters may be used to characterize whether the current physical network is suitable for configuring the virtual machine.
In step S130, a physical network meeting a preset condition is selected as the binding IP address of the virtual machine according to the network state parameter. The binding IP address is the target IP address. If the virtual machine binds the target address, the virtual machine is configured in the physical network of the target IP address. In step S140, binding the target IP address with the virtual machine is equivalent to deploying the virtual machine in the currently most suitable physical network, so as to implement optimal deployment of the virtual machine, and reduce the problems of slow transmission of the virtual machine, unbalanced loads of different physical networks, excessive load of some physical networks, idle resources of some physical networks, and the like caused by randomly deploying the virtual machine.
In some cases, there may be currently available floating IP addresses that all belong to the same physical network, and at this time, one currently available floating IP address may be randomly selected as the target address. In some cases, there may not be a floating IP address currently available, and a new floating IP address needs to be created at this time as the target IP address. When creating the virtual IP address, the network state parameters can be obtained, the physical network which is most suitable for deployment is selected, and the newly created floating IP address is allocated to the physical network of the virtual machine which is most suitable for deployment.
In some embodiments, the step S120 may include:
acquiring at least one of a network load rate, an available transmission rate and a ratio of the number of configured virtual machines to the number of configurable virtual machines of the physical network corresponding to the current available floating IP address;
the step S130 may include:
and selecting the target IP address according to at least one of network load rate, available transmission rate, ratio of the number of configured virtual machines to the number of configurable virtual machines and application service attribute.
At least one of the following may be included in step S130:
and selecting the currently available floating IP address in the physical network with the lowest network load rate as the target IP address. The network load rate is a ratio of the current load capacity of the physical network to the maximum load capacity that can be provided, and the lower the network load rate is, the larger the data of the virtual machine that can be deployed by the physical network is, which is suitable for the deployment of the virtual machine.
Selecting a currently available floating IP address in the physical network of available transmission rates as the target IP address. Here, the available transmission rate is a remaining network transmission rate obtained by subtracting a currently occupied network transmission rate from a maximum transmission rate of the physical network. The larger the available transmission rate is, the more the virtual machine is deployed in the physical network, and the higher transmission rate can be obtained.
And selecting the currently available floating IP address corresponding to the physical network with the lowest ratio of the number of the configured virtual machines to the number of the configurable virtual machines as the target IP address.
The number of connectable virtual machines here represents the maximum number of virtual machines that can be configured in the physical network, and the number of configured virtual machines is the number of virtual machines that have been configured in the corresponding physical network. If the ratio is larger, it indicates that there are many virtual machines configured in the physical network, and continuing to configure may cause a problem of excessive configuration. The currently available floating IP address of the physical network with the lowest ratio is selected to be the most suitable physical network for configuring the virtual machine in terms of the dimension of the number of configurations.
In particular implementations, any of the above dimensions may be combined to select the physical network of the most optimally configured virtual machine at the present time.
For example, the step S130 may specifically include:
and calculating a deployment appropriateness value S of the physical network corresponding to the currently available floating IP address according to the following functional relation. The deployment suitability value S represents the suitability of the corresponding physical network for deploying the virtual machine.
S ═ T × N + P × m + N × i; wherein T represents the ratio of the number of configured virtual machines to the number of configurable virtual machines; the n is the weight corresponding to the T, and the value is positive; the P represents the network load rate; m is the weight of P, and the value is an integer; the N represents the available transmission rate; the i is the weight of the N and takes a negative value;
and selecting the currently available floating IP corresponding to the physical network with the minimum S as the target IP.
In the embodiment, the deployment proper value is calculated by utilizing the functional relationship, so that the method has the characteristic of simple and convenient implementation.
For example, the function min(s) may be used to select the physical network where the target IP address is located.
Further, the step S130 may further include:
acquiring network attribute parameters which can be provided by the physical network and correspond to the current floating IP address; wherein the network attribute parameters include application services provided by the physical network;
and taking the current floating IP address corresponding to the physical network matched with the application service type required by the virtual machine according to the network attribute parameter as the target IP address.
This step may be used in conjunction with the functional relationships previously described. If the currently available floating IP address corresponds to a plurality of physical networks, part of the physical networks which cannot provide the application service type required by the virtual machine to be deployed are screened out through the network attribute parameters. In the above functional relationship, a physical network most suitable for deploying the virtual machine currently is selected from physical networks which can provide application services required by the virtual machine, and a currently available floating IP address of the most suitable physical network is selected as the target IP address.
In some cases, if there is no floating IP address currently providing the application service required by the virtual machine, the created floating IP address is used as the target IP address for providing the floating IP address of the application service network required by the virtual machine.
In some cases, the method further comprises: if the application service required to be provided by the virtual machine changes, the floating IP address bound by the virtual machine is changed into a physical network providing the corresponding application service, so that the migration of the physical network where the virtual machine is located is simply and conveniently realized, and the simple migration and expansion of the virtual machine are realized.
The step S110 may include: responding to the virtual, namely creating request information, and inquiring a floating IP address list; a currently available floating IP address is selected from the list of floating IP addresses that is unused in use.
In the embodiment, the floating IP is managed by using the floating IP address list, so that on one hand, the effective management of the floating IP address is realized, and meanwhile, the query of the currently available floating IP address can be facilitated;
the method further comprises the following steps:
changing the usage status of the target IP address in the floating IP address to used after the binding of the target IP address with the created virtual machine.
After a floating IP address is assigned to a newly deployed virtual machine, in order to facilitate the deployment of a subsequent virtual machine, the use state of the floating IP address assigned to the corresponding virtual machine is configured to be used, so as to facilitate the deployment of a subsequent new virtual machine.
