Abstract
The present invention relates to the technical field of cloud computing, and particularly relates to a method of migrating a virtual machine of a XenServer platform to a KVM virtual platform. The method comprises the following steps of entering a host in which the XenServer virtual machine is; searching a vdi file corresponding to the virtual machine according to a script command; exporting the vdi file to a local file according to a DD command; copying the local file to a host in which the KVM platform is; converting the exported file into a qcow2 file according to a command; and creating a KVM platform virtual machine according to the qcow2 file. In the prior art, the operation is complex, the data is easy to loss, the occupation time is long when a P2V migration tool is used, and the migrated service stops for a long time. Through adoption of the method, problems in the prior art are solved.
Description
Technical field
The present invention relates to cloud computing administrative skill field, particularly relate to a kind of by XenServer platform virtual machine migrate to
The method of KVM virtualization platform.
Background technology
Under cloud computing environment, XenServer is the enterprise-level virtual platform in cloud computing environment through checking, can
There is provided the institute creating and managing needed for Virtual base framework functional.It is firmly got a lot of enterprises requiring harshness and trusts, and is used for
Run the application of most critical；And adopted by the cloud computing environment of maximum-norm and xSP.Domestic in early days also a lot of enterprises use
XenServer virtual platform, such as tide, Huawei etc..But XenServer is commercial version, expense costly, with
The emergence of KVM virtualization platform；Increasing enterprise uses KVM virtualization platform at present.So how that XenServer is empty
The virtual machine (vm) migration of planization platform to KVM virtualization platform also will be the big difficult point that we face.Compare the side of main flow at present
Method has following two：
(1) derive XVA file, by being decompressed to XVA file and being combined into image file mode.
(2) P2V Migration tools are passed through, virtual machine is treated as physical machine derives ISO mirror image, then imports KVM platform again.
There is following drawback in both the above mode：
(1) derive the mode complex operation that XVA file remerges, be easily caused loss of data.
(2) more long by P2V Migration tools holding time, the business downtime simultaneously migrating is longer.
In order to from truly realizing XenServer virtual machine (vm) migration to KVM virtualization platform, need a kind of safety
Stable, operate easy method.
Content of the invention
Present invention solves the technical problem that being to provide one kind to migrate XenServer platform virtual machine to KVM virtualization
The method of platform, solves the deficiency that conventional method exists, is that under cloud computing environment, XenServer virtual machine (vm) migration is virtual to KVM
Changing platform provides a kind of safe and reliable solution.
The present invention solves the technical scheme of above-mentioned technical problem：
Comprise the steps：
Step 1：Enter XenServer virtual machine place host；
Step 2：Virtual machine corresponding vdi file is searched by script command；
Step 3：Vdi file is exported to by local file by DD order；
Step 4：Local file is copied to KVM platform place host；
Step 5：Local file is changed into by qcow2 file by order；
Step 6：By qcow2 document creation KVM platform virtual machine.
Described step 2, specifically refers to what use was combined based on XenServer Virtual Machine Manager order itself
Linux script, perform script can find out virtual machine corresponding vdi file.
Described Linux script, including：
Check virtual machine correlation vdi uuid；
Check vdi associated storage information；
Check vdi storage location.
Described DD order is：
Refer to provide #dd if=vdi storage location of=to export local file path bs=2097152 count=
378.
Described step 4, specifically refers to using FTP or SCP order copy local file to KVM platform host.
Described step 5, specifically refers to create a disk unit, and the local file carry that copy is come, then
Carry out file format conversion.
Described qcow2 file, provides a kind of disk mirroring supporting KVM virtualization platform and KVM virtual machine template literary composition
Part.
The present invention program has the beneficial effect that：
The method of the present invention provides one kind to use copy mode the staged files, has ensured the complete of virtual-machine data file
Property, safe.
The method of the present invention pass through derive, copy and conversion can direct access virtual machine template file mode, simple to operate,
Used time is short.
Brief description
The present invention is further described below in conjunction with the accompanying drawings：
Fig. 1 is the flow chart of the inventive method.
Specific embodiment
As shown in figure 1, essential core of the present invention is to change to realize by underlying virtual machine file, specific implementation process
As follows：
1st, enter XenServer virtual machine place host；
2nd, virtual machine corresponding vdi file is searched by script command；
Script getVHD.sh core code is as follows：
#xe vbd-list vm-uuid=$ 1//check that virtual machine correlation vdi uuid, $ 1 are virtual machine uuid
#xe vdi-list uuid=$ 2//check vdi associated storage information, $ 2 are vdi uuid
#lvscan|grep<vdi-uuid>// search vdi storage location
3rd, vdi is exported to by local file by DD order；
#dd if=vdi storage location of=exports local file path bs=2097152 count=378
4th, local file is copied to KVM platform host；
Here FTP or SCP order copied files can be passed through
5th, the file translations of derivation are become by qcow2 file by order；
Core commands
#xmblock-attach 0tap2：tapdisk：vhd：Copy the file path xvdb w 0 coming
// create a disk unit, and the file mount that copy is come.
#qemu-img convert-p-0qcow2/dev/xvdb NYJ_TDCB_WEB_system.qcow2
// carry out file format conversion
Step 6：By qcow2 document creation KVM platform virtual machine, qocw2 is KVM virtualization platform virtual machine template
File.
