Fig. 1 is referred to, a kind of virtual machine application moving method one embodiment includes in the embodiment of the present invention：
101st, the machine probability of currently delaying of target server system is obtained；
In the present embodiment, it is possible, firstly, to obtain the machine probability of currently delaying of target server system.Above-mentioned machine of currently delaying is general
Rate can by target server system is carried out previous machine situation of delaying carry out statistical analysis prediction obtain.
It is understood that the machine probability of delaying of target server system is relevant with the time that it runs, and in general, target
The time that server system has run is longer, then machine probability of delaying is bigger.Fig. 2 shows server system under an application scenarios
The relation schematic diagram of machine probability and the run time of delaying.In Fig. 2, transverse axis represents number of days, and the longitudinal axis represents machine probability of delaying, and curve can in figure
To be expressed as machine probability y=f (t) of delaying, knowable to curve, increase over time, the machine probability of delaying of server system is bigger.
Therefore, further, above-mentioned steps 101 specifically can include：Obtain the operation of the target server system
Time, then run time and default machine probability function of delaying obtain currently delaying for the target server system according to

It is determined that after each virtual machine application on the target server system, can obtain it is described each
The using value of virtual machine application.It is understood that the using value of these virtual machine applications can carry out in advance assessment and
Arrange, if the significance level of a virtual machine application is higher, the value of its corresponding using value is bigger；If a conversely, void
The significance level of plan machine application is lower, then the value of its corresponding using value is less.
104th, according to the using value and the target clothes described in machine determine the probability of currently delaying of each virtual machine application
The current drain value of business device system；
Getting the using value and the machine of currently delaying of the target server system of each virtual machine application

The application total value of individual virtual machine application isWhen there is delaying machine in the target server system, the destination server system
Virtual machine application on system will lose, and its loss value can be represented with S, then the current drain value of the target server system
Can be represented with loss value computing formula:
Therefore, when obtaining the application total valueAfter machine probability f (t) of currently delaying, can substitute into
State loss value computing formula and be calculated current drain value S.
If the 105, the current drain value meets default loss condition, described each virtual machine application is migrated
Process.
It is determined that after the current drain value of the target server system, if the current drain value meets default damage
Consumption condition, then carry out migration process to described each virtual machine application.
It is understood that specifically, in order to reduce machine loss of delaying, maximum loss value S can be presetmax, control should
Current drain value S of target server system meets S<Smax.During the routine use of target server system, with when
Between t increase, machine probability f (t) of currently delaying also can increase, then current drain value S can gradually approach Smax.As S >=SmaxWhen, then may be used
To think that current drain value meets default loss condition, now then need to carry out at migration described each virtual machine application
Reason, to reduce the machine loss of delaying that target server system is likely to occur.
Further, carrying out migration process to described each virtual machine application specifically can include：Each is virtual to described
Machine application carries out whole migrations；Or, the virtual machine application to meeting default transition condition is migrated.It is understood that
When needing to carry out migration process to virtual machine application, all of virtual machine application can be migrated, it is also possible to migrate the void of part
Plan machine application so that current drain value S is reduced.
Further, the virtual machine application to meeting default transition condition is migrated and specifically can include following two
Plant the one kind in migration pattern.
The first migration pattern is：Determine the virtual machine application of the using value more than default value threshold value；To true
The fixed virtual machine application is migrated, i.e., preferentially migrated the higher virtual machine application of using value.
Second migration pattern be：Obtain the last transit time of each virtual machine application；Determine described upper one
Secondary transit time meets the virtual machine application of default time conditions；Pair determine the virtual machine application migrate.
It is understood that second migration pattern tends to last transit time preferentially apart from the more long void of present system time
Intend application to be migrated.Due to for a virtual machine application, often repeatedly being migrated excessively, namely can be in multiple clothes
Corresponding data are remained with business device system.Therefore, twice transit time interval is longer before and after virtual machine application, then represent
The data loss probability of the virtual machine application is bigger.In order to twice transit time interval should not be long before and after controller, so as to can
To choose second migration pattern, preferentially to last transit time, earlier virtual machine application is migrated.
It is understood that two kinds of above-mentioned migration patterns can carry out selectively using according to actually used situation,
Can be combined together and be used.
In the present embodiment, first, the machine probability of currently delaying of target server system is obtained；It is determined that installed in target clothes
Each virtual machine application in business device system；Obtain the using value of each virtual machine application；Then, according to it is described each
The current drain value of the using value of virtual machine application and the target server system described in machine determine the probability of currently delaying；If institute
State current drain value and meet default loss condition, then migration process is carried out to described each virtual machine application.In the present embodiment
