Fig. 1 is the process flow diagram of the control method embodiment mono-of resource multiplex of the present invention.As shown in Figure 1, the control device that the executive agent of the present embodiment is resource multiplex, this control device can adopt the mode of software and/or hardware to realize, and preferred, this control device can be integrated in physical server, and this control method comprises:
S101, obtain the resource using information of each VCPU in virtual machine.
On physical server, can move a plurality of virtual machines, the plurality of virtual machine can be shared the resource of this physical server, but in order to control each virtual machine to the rational time-sharing multiplex of resource, need to know the use information of each virtual machine to resource, concrete, for each virtual machine, in obtaining virtual machine during the resource using information of each VCPU, can pass through the monitoring in one period of cycle, know the use information of each VCPU to resource in each virtual machine, as larger in the portfolio between 18:00 to 22:00 in found a VCPU of certain virtual machine by monitoring, for other VCPU, the resource duration more or use resource taking is longer, or can be by real-time monitoring, find the behaviour in service in the past one hour of each VCPU in each virtual machine.
S102, according to the resource using information of each VCPU, adjust the occupancy of each VCPU to resource.
As lower to the utilization rate of resource in certain VCPU, can shorten the take duration of this VCPU to resource, thereby other can have the more duration that takies to resource to the higher VCPU of the utilization rate of resource.
In the present embodiment, by the resource using information of each VCPU in the virtual machine obtaining, the occupancy of each VCPU to resource in the adjustment virtual machine of adaptation, does not change state and the specification of virtual machine, realizes the rational time-sharing multiplex of each VCPU to resource.
Fig. 2 is the process flow diagram of the control method embodiment bis-of resource multiplex of the present invention.As shown in Figure 2, the present embodiment is on the basis of the embodiment shown in Fig. 1, describes a kind of possible implementation, and concrete, this control method comprises:
S201, monitor the utilization rate of each VCPU to resource in virtual machine in real time.
In the present embodiment when carrying out S201, for each virtual machine, and specifically to take each VCPU be example to the utilization rate of resource to the resource using information of each VCPU in the present embodiment, in actual applications, the resource using information of each VCPU can also be the occupancy of each VCPU to resource, such as being allocated in the quantity of core of VCPU and other physical resources etc.
S202, according to the resource using information of each VCPU, adjust the occupancy of each VCPU to resource.
Concrete, the monitoring of above-mentioned S201 is to carry out according to the time period, by monitoring, find, if a VCPU is more than or equal to the first predetermined threshold value to the utilization rate of resource in very first time section, a VCPU is increased to lengthening duration to the duration that takies of resource by normal duration;
Wherein a VCPU is any one in above-mentioned each VCPU, and one section of duration that very first time section can start for any time such as 1 hour, 2 hours, for example, very first time section is that 6:00 was by one hour of 7:00, now controlling the duration that each VCPU takies resource is 10s, be called normal condition, and for each VCPU, VCPU is normal duration to the duration 10s that takies of resource; And within this very first time, it is above-mentioned the first predetermined threshold value that the utilization rate of finding a VCPU continues within 1 hour, to remain on 80%() more than, a VCPU is adjusted into and is increased 20%(20% only for giving an example by normal duration the duration that takies of core, the concrete ratio of adjusting can be preset as required), by normal duration, increase to lengthening duration;
Further, after described very first time section, if the second time period in a VCPU to the utilization rate of resource less than or equal to the second predetermined threshold value, a VCPU is reverted to described normal duration to the duration that takies of resource by lengthening duration.
That is to say, above-mentioned by normal duration, increased to lengthen duration after, the utilization rate of finding a VCPU after monitoring by S201 continues 2 hours (being above-mentioned the second time period), and to remain on 20%(be above-mentioned the second predetermined threshold value) below, a VCPU is taken to duration by reverting to described normal duration by lengthening duration to core; The time period now starting continues as understandable, above-mentioned by normal duration, increased to lengthen duration after, the one VCPU is not more than or equal to the first predetermined threshold value to the utilization rate of resource, and not less than or equal to the second predetermined threshold value, a VCPU remains unchanged to the duration that takies of resource.
Accordingly, the low situation of the utilization rate to resource for a VCPU under normal condition, similar to the above, even in very first time section, a VCPU is less than or equal to the 3rd predetermined threshold value to the utilization rate of resource, and a VCPU is reduced to shortening duration to the duration that takies of resource by normal duration;
Further, after very first time section, if a VCPU is more than or equal to the 4th predetermined threshold value to the utilization rate of resource in the second time period, a VCPU is reverted to normal duration to the duration that takies of resource by shortening duration.
Above-mentioned very first time section and the second time period are relative concept, along with each VCPU is constantly become and lengthened duration or shorten duration from normal duration, and revert to normal time by lengthening duration or shortening duration, very first time section and the second time period occur successively, thereby S201 and S202 are along with the arrival circulation of time period is each time performed, to realize the time-sharing multiplex of each VCPU to resource.
