Wherein, after sequential encoding generates, sequential encoding is unique in the whole life cycle of this virtual machine to be determined, i.e. sequential encoding in this virtual machine identifier can be with the attribute change of this virtual machine, as: when virtual machine moves, the attribute such as clone or Hot Spare is while changing, the sequential encoding of this virtual machine does not change.
Attribute coding:
Wherein, attribute coding is determined by corresponding virtual machine real-time property; Constituent content, constituent number and the constituent of the present invention to attribute coding puts in order and do not do any restriction, and attribute coding's composition concrete form can be determined according to user's actual needs and the attribute coding who pre-sets standard scale.Below only simple as example taking a kind of attribute coding's possible composition form.
For example: obtain a certain virtual machine real-time property as shown in Table 1, according to user's actual needs and attribute coding's standard scale of pre-seting, determine that attribute coding can be encoded by system property, security attribute coding and service attribute coding form.
The corresponding virtual machine time encoding of system property coding, physical attribute coding and operating system attribute coding composition; Time encoding is 46 bits; Time encoding represents the corresponding virtual machine creating time; Physical attribute coding physical location attribute coding and computer node coding composition; Physical location attribute coding is 8 bits; Physical attribute coding represents the physics machine room scope at the current place of corresponding virtual machine; Computer node is encoded to 20 bits; Computer node coding represents the computing node of corresponding virtual machine in the physics machine room of current place; Operating system attribute coding is 4 bits; Operating system attribute coding represents corresponding virtual machine current operation system type.Security attribute coding security domain attribute coding and migration attribute coding composition; Security domain attribute coding is 8 bits; Security domain attribute coding represents the current place of corresponding virtual machine security domain; Migration attribute coding is 4 bits; Migration attribute coding represents the migration grade of corresponding virtual machine.Service attribute coding type of service coding and service application scope coding composition; Type of service is encoded to 4 bits; Type of service coding represents the type of service of the current carrying of corresponding virtual machine; Service application scope is encoded to 5 bit compositions; Service application scope coding represents the range of application of the current bearer service of corresponding virtual machine.
Wherein, carry out virtual machine attribute coding according to the each attribute coding's standard scale pre-seting, usually, a cloud computing platform arranges a set of each attribute coding's standard scale, the standard that arranges of attribute coding's standard scale is definite according to active user's actual needs, and the present invention only may illustrate with one.
Wherein, time encoding computational methods be by current time taking millisecond as interval, be converted into start 0: 0: 0 on the 1st January in 2000, according to the binary system timestamp of millisecond counting.The for example creation-time of virtual machine A is 12: 32: 50 on the 3rd April in 2013, calculates the current distance initial time time difference to be: 13 years 3 months 2 days 12 hours 32 minutes 50 seconds; Time difference is converted into millisecond number: (3*,365,*24,*60,*60,+3*,30*,24*,60*,60+,2*2,4*6,0*6,0+1,2*6,0*6,0+2,4*6,0+5 0) * 1000=102,601,490,000; Millisecond number is converted into 46 bits and is: 0000000001011111100011100001100111111001010000, and the time encoding in virtual machine attribute coding is: 0000000001011111100011100001100111111001010000.
Unique computing node in physics Host equipment room of computing node code identification.For example the computing node of virtual machine A is 1024, converts 20 bits to be: 00000000010000000000, and the computing node of virtual machine A is encoded to 00000000010000000000.
