Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole embodiments.Based on this
Embodiment in invention, those of ordinary skill in the art are without making creative work, obtained every other
Embodiment belongs to the scope of the present invention.
Core of the invention is to provide a kind of band snapshot virtual machine complete machine dynamic migration method and device.
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Fig. 1 is a kind of flow chart with snapshot virtual machine complete machine dynamic migration method provided by the invention.Fig. 2 is the present invention
The corresponding building-block of logic of a kind of source storage equipment provided.Fig. 3 is that a kind of destination provided by the invention stores equipment pair
The building-block of logic answered.As shown in Figure 1, including: with snapshot virtual machine complete machine dynamic migration method
S10: the logical construction in detection source magnetic disk of virtual machine between source disk file and snapshot, and save.
S11: after receiving migration order, source storage equipment is opened with the transmission channel of target side storage equipment to pass
The defeated transmission data being made of source disk file and snapshot.
S12: extensive in target side storage equipment according to logical construction after transmitting the basic data end of transmission in data
The logical relation of multiple source virtual machine disk.
S13: after basic data is recovered, using mirror function the dynamic data synchronization in data will be transmitted extremely
Target side stores the target virtual machine disk in equipment, and current virtual machine operating status is switched to mesh by source storage equipment
It marks end and stores equipment.
After receiving migration order (having band snapshot virtual machine complete machine dynamic migration demand), detection source storage first is set
Logical construction in the source virtual machine disk set between source disk file and snapshot, and save.As shown in Fig. 2, source disk is literary
Part is the inherent data that source stores disk in equipment, if not carrying out beating snapshot, source disk file is exactly above to move
State data (transmission data are divided into dynamic data and basic data), are exactly basic data otherwise.If having carried out beating snapshot,
First snapshot Snap-1 is exactly dynamic data, if as soon as making a call to Zhang Kuaizhao again, then first snapshot Snap-1 becomes basic number
According to second snapshot Snap-2 is exactly dynamic data, if as soon as making a call to Zhang Kuaizhao again, then second snapshot Snap-2 becomes basis
Data, third Zhang Kuaizhao Snap-3 is exactly dynamic data, and so on.It can be seen that being moved in band snapshot virtual machine complete machine dynamic
Always with the presence of dynamic data and basic data during moving.
The preparation being equivalent to after having detected logical construction before completing migration, at this time if receiving migration order
Afterwards, the transmission channel of source storage equipment and target side storage equipment is opened.
In specific implementation, the moving method of dynamic data and basic data is different, and the moving method of basic data can be with
It is directly to transmit, but the moving method of dynamic data needs to utilize mirror function.The migration of dynamic data cannot be adopted directly
With the mode of reading, need to synchronize using mirror function.
It is the transmission for carrying out basic data first, source storage equipment can be read directly in the transmission of basic data here
Data in magnetic disk, after basic data end of transmission, the logical construction saved according to step S10 is extensive in target side storage equipment
The logical relation of multiple source virtual machine disk, i.e., place whole basic datas according to original structure.
Then, using mirror function, by target virtual machine disk of the dynamic data synchronization into target side storage equipment.
As shown in Figures 2 and 3, the corresponding building-block of logic of target side storage equipment building-block of logic phase corresponding with source storage equipment
Together, it only in this way just can guarantee that transmission data are not chaotic.
At this point, whole transition process is completed, since current virtual machine operating status still stores in setting in source,
Therefore, it is necessary to current virtual machine operating status is switched to target side storage equipment by source storage equipment.
As a preferred embodiment, further include: transmission channel is adjusted in transmitting the transmission data procedures
Transmission rate.
It in transmission process, needs to adjust the transmission rate of transmission channel at any time, high speed data transfer is avoided with this, occupy
Physical server upper layer network I/O specific gravity is excessive, and influences physical server performance.It is understood that transmission rate how
Depending on adjustment needs the operating status according to physical server upper layer network, the present invention is repeated no more.
As a preferred embodiment, further include: band snapshot virtual machine complete machine dynamic migration process is completed in prompt.
Since above-mentioned steps need certain execution time, in order to allow user recognize in time transition process into
Degree exports prompt information after the completion of transition process to prompt user's transition process to finish.
A kind of band snapshot virtual machine complete machine dynamic migration method provided in this embodiment, first detection source disk file and fast
Logical construction according between, and save；Then the basic data in data will be transmitted, and logically structure restores logical relation, then
Remaining dynamic data is synchronized using mirror function, the mistake with snapshot virtual machine complete machine dynamic migration is completed with this
Journey.

According to；
Data in magnetic disk logic recovery module 12 is connect with Data Migration transmission module 11, for when the basis in transmission data
Logical relation after data end of transmission, according to logical construction recovery resource magnetic disk of virtual machine in target side storage equipment；
Mirror synchronization module 13 is connect with data in magnetic disk logic recovery module 12, for being recovered when basic data
Afterwards, using mirror function target virtual machine magnetic of the dynamic data synchronization in data into target side storage equipment will be transmitted
Disk, and current virtual machine operating status is switched into target side storage equipment by source storage equipment.
After receiving migration order (having band snapshot virtual machine complete machine dynamic migration demand), detection source storage first is set
Logical construction in the source virtual machine disk set between source disk file and snapshot, and save.As shown in Fig. 2, source disk is literary
Part is the inherent data that source stores disk in equipment, if not carrying out beating snapshot, source disk file is exactly above to move
State data (transmission data are divided into dynamic data and basic data), are exactly basic data otherwise.If having carried out beating snapshot,
First snapshot Snap-1 is exactly dynamic data, if as soon as making a call to Zhang Kuaizhao again, then first snapshot Snap-1 becomes basic number
According to second snapshot Snap-2 is exactly dynamic data, if as soon as making a call to Zhang Kuaizhao again, then second snapshot Snap-2 becomes basis
Data, third Zhang Kuaizhao Snap-3 is exactly dynamic data, and so on.It can be seen that being moved in band snapshot virtual machine complete machine dynamic
Always with the presence of dynamic data and basic data during moving.
The preparation being equivalent to after having detected logical construction before completing migration, at this time if receiving migration order
Afterwards, the transmission channel of source storage equipment and target side storage equipment is opened.
In specific implementation, the moving method of dynamic data and basic data is different, and the moving method of basic data can be with
