Description
Technical field
It is specifically a kind of to realize what is migrated between virtual platform the present invention relates to cloud computing administrative skill field
V2V methods.
Background technology
V2v migratory system and data and handles main frame difference and virtual hardware between virtual machine, the source virtual machine in v2v
System can such as be moved with purpose dummy machine system type with identical or different between VMware and KVM or inside respective
Move.V2v moving methods include offline migration, online migration and internal memory migration.Offline migration is needed virtual machine before carrying migration
Pause, and virtual machine image and state are copied to destination host simultaneously, offline migration has certain service unavailable time, but
It is simple and easy, suitable for the less demanding occasion of service availability.Offline migration is that solve to move between different type virtual machine
The effective way of shifting, the Migration tools virt-v2v that such as increases income are exactly to use this mode by the virtual machine of VMware and KVM types
Migrate to KVM platforms and load KVM driving successful operation.Online migration can guarantee that virtual machine is normally transported in transition process
OK, migration initial stage provides service by source host, then adapter service, switching after destination host possesses the necessary resource of runtime
Process is extremely short, and transition process is transparent to user, suitable for requiring higher occasion to service availability.Internal memory migration can use pre-
Copy strategy, source host virtual machine memory data is sent to destination host virtual machine by circulating, pre-copy strategy, passes through circulation
Source host virtual machine memory data is sent to destination host virtual machine, pre-copy circulation enters after terminating shuts down copy stage, source
Main frame, which is hung up, no longer updates internal memory, and pre-copy mechanism greatly reduces the internal memory transmission quantity in shutdown stage, and downtime contracts significantly
It is small.
The virt-v2v instruments of Red Hat companies exploitation.It is the script write by perl language, can be automatic
The virtual machine that will be created on Xen, KVM and VMware ESX of change copies virt-v2v main frame to, and automatically
Change configuration, enable to be managed by libvirt.At present, virt-v2v supports the following virtual machine of static migrating：
RHEL4, RHEL5, RHEL6, Windows XP, Windows Vista, Windows 7, Windows Server 2003
With Windows Server 2008.
Virt-v2v instruments are deployed on a KVM main frame, and are come using a local directory is created to store migration
Virtual machine image, in addition to realizing automation migration virtual machine, first pre-set virt-v2v.conf files, set one
The rule of a little virt-v2v migrations, including the mapping after network interface migration, the mode of migration, the position of storage, the lattice of output
Formula etc..These rules can also be inputted in a manner of command line parameter, such as -- network ,-o ,-os ,-of etc..To be automatic
Log in VMware ESX servers and create .netrc files.And 0600 authority, file content machine are set
Esx.example.com login root password xxxxxx form.
Virt-v2v orders are reused to be migrated.
KVM is moved to from Xen：virt-v2v-ic xen+ssh://root@xen0.demo.com -os pool -b
brnamevm-name。
KVM is moved to from VMware：virt-v2v-ic esx://esx.demo.com/ -os pool --
bridegebramevm-name。
Prior art has the drawback that：（1）, each manufacturer virtual machine be unable to flexible conversion；（2）, do not support each manufacturer
Virtual machine between mutually migrate.
Patent No. CN 106406979A patent document disclose it is a kind of by XenServer platform virtual machines migrate to
The method of KVM virtualization platform.The method of the present invention comprises the following steps：Host where into XenServer virtual machines；It is logical
Vdi files corresponding to crossing script command lookup virtual machine, local file is exported to by DD orders by vdi files；Will local text
Part copies host where KVM platforms to；By ordering derived file translations into qcow2 files, created by qcow2 files
Build KVM platform virtual machines.But the virtual machine that the technical scheme can not solve each manufacturer is unable to flexible conversion and not supported each
The problem of mutually being migrated between the virtual machine of manufacturer.
The content of the invention
