Wherein, described overall scheduler module 300 is additionally operable to: hangs source host I/O and recovers described source host I/O.
Wherein, described overall scheduler module 300 includes:
Delete unit, migrate online after successfully for the virtual machine in unshared storage, delete source host disk.
Wherein, between without two storage pools of share host, automatically set up intermediate transmission media, be used for performing virtual machine storage data and internal storage data migration, control module by the migration in overall scheduler module and source host to coordinate, it is achieved the virtual machine complete machine thermophoresis between unshared storage.Therefore, here source host is all relative with destination host, the main frame carrying out migrating is needed to be called source host, receive the main frame migrating main frame and be called destination host, therefore each main frame in this system can be provided with intermediate medium management services module and migrates and control module, and intermediate medium management module here can complete the repertoire of above-mentioned first intermediate medium management module and the second intermediate medium management module i.e. intermediate medium management module here and comprise the first above-mentioned intermediate medium management module and the second intermediate medium management module；Wherein, intermediate medium management services module is based on specific local share directory, and management NFS shares storage service, and virtual machine utilizes this intermediate medium management services module to realize online complete machine to migrate after associative operation completes, and NFS service is closed in management；Migrate and control module and utilize and perform I/O mirror image between different pieces of information storage file, and replicate valid data, it is achieved on-line storage data syn-chronization replicate, the virtual machine of running status is serviced the opposite end store path of carry from the unshared locally stored NFS that moves to online.Whole system also includes an overall scheduler module, is used for controlling the online complete machine of unshared storage and migrates execution flow process, intermediate medium management services module and migration are controlled the scheduling of module rationalization.Combined with virtual machine migrating technology, it is achieved the unshared storage complete machine of virtual machine migrates online.Wherein, intermediate medium management services module and migration control module and are deployed in host node, and overall scheduler module can be deployed in virtual management platform service.As it is shown in figure 5, main frame 1 can for source host can also for the purpose of main frame.
The characteristic of intermediate medium management services module, it is primarily referred to as and automatically manages intermediate storage medium, automatically controlling medium connection between source host and destination host, to realize the shared transmission medium that storage migrates, additionally configurable overlapping trees realizes the purpose of flexibility management more；Migrating the characteristic controlling module, be primarily referred to as and use the on-line storage that I/O mirror image performs between unshared storage and intermediate medium storage to migrate, this module is first carried out opposite end accessible detecting before migrating, it is to avoid waits as long for time-out and exits the waste execution time.The characteristic of overall scheduler module, is primarily referred to as control intermediate medium management services module and migrates control module work, dispatching unshared storage and migrate overall flow online, it is ensured that abnormal rollback success, it is ensured that migrate deletion source magnetic disk of virtual machine after successfully.
Based on technique scheme, here using main frame 1 as source host, when main frame 2 is as destination host, above-mentioned transition process specifically may is that
When the virtual machine of presence performs by main frame 1, local unshared storage 1 to when migrating in main frame 2, local unshared storage 2, after overall scheduler module receives migration message, first sending a message to the intermediate medium management services module of move target main frame 2, intermediate medium management services module can be set up, at destination host 2, the NFS being share directory with purpose storage address and service.Now overall scheduler module sends instruction to the intermediate medium management services module on source host 1, uses the NFS service of the newly-built catalogue carry destination host 2 of local disk.After carry completes, overall scheduler module migrates to source host 1 and controls module transmission on-line storage migration instruction, the migration of main frame 1 controls module will perform the magnetic disk of virtual machine file magnetic disc i/o mirror image operation to shared NFS service catalogue new files, and copy valid data, repeatedly dish virtual machine performs this operating process repeatedly.After on-line storage migration operation terminates, overall scheduler module sends virtual machine host to source host 1 and migrates instruction, and virtual machine performs host migration, and now, the unshared storage complete machine of virtual machine migrates successfully online.Migrating after successfully, overall scheduler module to be sent to the intermediate medium management services module of source host 1 and disconnect NFS service connection, and sends stopping NFS service order to the intermediate medium management services module of destination host 2.Disconnect NFS to connect and before and after stopping NFS service execution in process, it is necessary to hung the virtual machine I/O short time, in order to avoid virtual machine is impacted by the operation stopping NFS service.
Based on technique scheme, the system that the virtual machine of the unshared storage that the embodiment of the present invention provides migrates online, realize source host end to the storage migration of destination host end and host migration, realize the online virtual machine (vm) migration of unshared storage, low cost mainframe cluster especially for unshared storage, the introducing of the method achieve virtual machine different main frames locally stored between same management and running, solve the problem that virtual machine cannot migrate.
