Use Vboxmanage to turn the virtual machine format VDI, VMDK, VHD

Virtual machine As the name implies is virtual machine (virtual machines), virtualization technology is also the most popular IT industry technology, because it can more effectively use hardware resources, integration of IT applications, reduce TCO, energy conservation and environmental protection, plainly speaking is a hardware strong enough machine, Can be on its virtual multiple machines, such as a room in the original 100 servers to provide a variety of services, using a virtualization solution, we only need to be on a machine can be virtual out of these 100 machines on its running, so that the overall cost savings is certain, daily operation and maintenance is more green, Energy saving and emission reduction, maybe you would think, so that all the eggs in a basket to increase the risk factor, indeed, this is correct, but we do not have to worry about this, virtual technology vendors have been for us to consider, can adopt the relevant fault-tolerant, clustering technology (such as Microsoft Live Migration, VMware's vmotion technology, any technology without security, is not a qualified mature technology, it is not possible to launch to the market, some immature technology is only for testing use. ）

Of course, virtualization technology is not just a virtual computer, there are many, such as virtual network, virtual storage, virtual applications and so on ...

In this article, we'll just discuss how to use Vboxmanage to convert three common virtual machine file formats, first let's look at what these three formats are:

1. VDI format: VirtualBox created by default hard disk file format, (about VirtualBox was originally developed by a German software company Innotek virtual system software, then by Sun acquisition, and then Sun was acquired by Oracle, VirtualBox is a powerful virtual machine software, not only a rich feature, but also excellent performance.
2. VMDK format: Virtual hard disk File format created by VMware (for VMware, the world's most bull B Company in virtual machines, currently a wholly owned subsidiary of EMC)
3. VHD format: For Microsoft virtual machine hard disk file format, (about Microsoft virtual machine technology, from the initial vpc,vserver2005r2, HYPER-V2008,HYPER-V2008R2, to this will be the Hyper-V 8beta, after multiple improvements, In the new version of Hyper-V 8beta, you will find very exciting Feature, such as the advent of new hard disk format VHDX, space technology from 2T to 16T, protecting data and ensuring quality performance on large sector disks, etc.)

The conversion of these three virtual hard disk formats can be done through a number of third-party tool software, this article describes how to use VirtualBox's own vboxmanage for format conversion:

1.vboxmanage.exe in the VirtualBox installation directory, for example, we enter the VirtualBox installation directory to view the VBoxManage.exe

2. command line into the VirtualBox directory, run the relevant vboxmanage format conversion instructions, the syntax is as follows:

Vboxmanage Clonehd source Hard disk format file directory hard disk format file--format destination format suffix

3. Turn the VDI file into a VHD file, such as a command to convert a VDI virtual machine file into a Microsoft VHD virtual machine file:

Execution progress to 100% finish conversion, then we use Microsoft virtual machine software mount to run smoothly

At this point, the use of vboxmanage on three common virtual hard disk format conversion end, VMDK, VHD to VDI and so on format.
