Virtual machine (vm) migration
Virtual machine migration technology provides easily method for server virtualization.Virtual machine (vm) migration refers to work as data center
Need to adjust the resource allocation of virtual machine between middle host, when certain host needs repairing, a virtual machine
System moves to the process of another physical host from a physical host.The essence of the migration of virtual machine is complete state
Migration, such as the content in CPU state, internal memory and disk.
It is as follows that virtual machine (vm) migration flow is carried out using internal memory pre-copy method in the prior art：
Step 0：After operation has virtual machine on host A, in order to be ready in advance to following possible virtual machine (vm) migration, provide
Target of what a main frame as migration, such as host B will be pre-selected in management system RMS.
Step 1：Resource management system RMS sends order, determines a virtual machine such as VM1 on migration host A to main frame
B, host B feedback information（As whether oneself can accommodate another virtual machine）Standard is decided whether according to feedback information to RMS, RMS
Standby migration.Resource abundance may also be determined in step 0, can migrate.
Step 2：Assuming that the result of step 1 is to migrate, migration management module performs virtual machine (vm) migration on host A.Such as
Fruit uses dynamic migration technology, then VM is still run on source host A, and host A is in an iterative manner by VM internal memory page copy
Onto host B, the first round copies all pages, and later each round only copies what is be modified in previous round iterative process
Page, by that analogy, until iterations reaches maximum iteration or remaining containing dirty pages are reduced to a predetermined value, Ran Houjin
Enter to the Stop-and-Copy stages.If using static migrating technology, the VM on source host A is shut down, and is entered directly into
The Stop-and-Copy stages.
Step 3：Entering the Stop-and-Copy stages, the VMM on host A hangs up source virtual machine, and network redirection
To target virtual machine, then remaining containing dirty pages and CPU state are moved to host B by migration management module in this stage.
Step 4：Host B sends message to host A and represents to be successfully received virtual machine, and host A is confirmed and destroyed
Source virtual machine, host B enable the virtual machine of migration.
Step 5：The virtual machine on host B is moved to using the device drives on B, and issues new ARP message.
