Description
Technical Field
The invention belongs to the technical field of virtual machines, and particularly relates to a method for improving the scheduling efficiency of physical nodes of a created virtual machine.
Background
At present, Openstack creates a scheduling algorithm of a virtual machine for a physical node. Firstly, screening the physical nodes on the level of the residual resources according to a filter; then, calculating the weight of each physical node passing the screening, and sequencing according to the weight; and finally, selecting the physical node with the maximum weight to create the virtual machine. The method fixes the situation that the physical node is traversed twice, and is not efficient.
Disclosure of Invention
In view of the above, the present invention provides a method for improving scheduling efficiency of creating a virtual machine physical node, aiming to overcome the above-mentioned defects in the prior art.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a method for improving the scheduling efficiency of creating a virtual machine physical node comprises the following steps:
s1, sorting physical nodes according to weight;
s2, selecting a physical node with the highest weight, and judging whether the physical node meets the requirement;
s3, if yes, returning; otherwise, the next physical node is selected according to the sorting in the step S1 until one node can meet the requirement, and then the process returns.
Further, in the step S1, a weight of each physical node needs to be calculated, and the physical nodes are sorted according to the weight.
Further, if the physical node selected in the step S2 and the step S3 does not satisfy the requirement, the weight of the physical node is modified to 0.
Compared with the prior art, the invention has the following advantages:
the physical node with higher weight has better resource residual condition and higher probability of filtering through the filter. In most scenes, the first physical node can pass through filtering, so that secondary filtering is avoided, the scheduling efficiency of the physical node can be improved, and the creation efficiency of the virtual machine is improved; the operation and maintenance can also design different weight calculation formulas according to the actual physical nodes and the filter characteristics, and further improve the probability that the high-weight physical nodes are filtered by the filter.

Detailed Description
It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.
In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings, which are merely for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be construed as limiting the invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the invention, the meaning of "a plurality" is two or more unless otherwise specified.
In the description of the invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be construed broadly, e.g. as being fixed or detachable or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.
The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.
As shown in fig. 1, a method for improving scheduling efficiency of creating a physical node of a virtual machine includes the following steps:
s1, sorting physical nodes according to weight;
s2, selecting a physical node with the highest weight, and judging whether the physical node meets the requirement;
s3, if yes, returning; otherwise, the next physical node is selected according to the sorting in the step S1 until one node can meet the requirement, and then the process returns.
In step S1, the weight of each physical node needs to be calculated, and the physical nodes are sorted according to the weight.
And if the physical node selected in the step S2 and the step S3 does not meet the requirement, modifying the weight of the physical node to 0.
The schematic diagram of the virtual machine scheduling algorithm adopted by Openstack at present is shown in fig. 2, when a physical node passes through Filters, one traversal is performed, after Host1 and Host4 are filtered out, the Weighting process performs another traversal on the remaining physical node, and therefore the two traversals in the whole process are essential.
The weight calculation and the sequencing of the physical nodes are placed to the first step of the scheduling algorithm by adjusting the scheduling algorithm of the physical nodes in the virtual machine creating process, and the screening process of the physical nodes is placed to the second step,
generally speaking, the physical nodes with higher weights have better resource remaining status and higher probability of being filtered by the filter. Therefore, in most scenes with relatively reasonable weight calculation, the first physical node can pass through filtering, and the second filtering in the attached figure 2 is avoided, so that the scheduling efficiency of the physical node can be improved, and the creation efficiency of the virtual machine is improved. The operation and maintenance can also design different weight calculation formulas according to the actual physical nodes and the filter characteristics, and further improve the probability that the high-weight physical nodes are filtered by the filter.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
