Embodiment Construction

[0036] Such as figure 1 As shown, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0037] (1) Download the virtual machine-related files that need to be migrated from the VMware ESXi client

[0038] Its downloaded file contains the following vmdk files:

[0039] Web-000001.vmdk, Web-000002.vmdk, Web-flat.vmdk, etc.

[0040] (2) Obtain the virtual machine data files in the vmdk format of the latest time point of these files

[0041] Method 1: View the downloaded vmdk disk file information on the KVM platform, and you can view it with ls-al.

[0042] Method 2: View the latest vmdk file on the VMware client;

[0043] Through one of the above two methods, the vmdk file obtained at the latest time point is the Web-000002.vmdk file

[0044] (3) Query the dependencies between the files in the vmdk format through the qemu-img info comma...

Abstract

The invention relates to the field of cloud computing, and particularly relates to a method of migrating a virtual machine from VMware to KVM. The migrating method comprises the steps of first, downloading related files of a virtual machine to be migrated from a VMware ESXi client, wherein the files comprise virtual machine data files of a vmdk format; acquiring files of the vmdk format at a latest time point; inquiring a dependence between the files of the vdmk format according to a qemu-img info command; checking the integrity of the dependence; converting the vmdk files at the latest time point into files of qcow2 format according to a qemu-img convert command; and starting a KVM virtual machine through a libvirt configuration file. The invention provides a method of migrating a VMwarevirtual machine to KVM.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a method for migrating a virtual machine from VMware to KVM. Background technique [0002] The VMware platform is a foreign virtualization platform. The platform is relatively expensive, and the virtualization technology is not open source. There may be security risks and it is difficult to find the problem, which increases the operation and maintenance costs and security risks. The KVM virtualization platform is open source, and many companies, enterprises and institutions have participated in its projects. Its performance, stability and security have been verified, and problems can be quickly solved if they are discovered in time; therefore, cloud platform demanders will gradually start from The VMware platform is migrated to the KVM virtualization platform. At present, the commonly used method of migrating virtual machines from VMware to KVM is to first merge multiple files of ...
