Converting VMware disk images to use in KVM

From time to time, you may have a need to convert a VMware based virtual disk image into some other format.

If you use KVM as your virtualization technology or perhaps you are migrating from VMware to KVM, you will need to convert your VMware disk images (.vmdk files) into a supported image type that you can use in KVM.

 

Individual Image files

If you have a single vmdk file, you can convert it with the below command.

Just over a week ago I sat the VMware Install, Manage and Configure training course as a prerequisite to gaining my VCP accreditation. I have been using VMware products for around 10 years now, so I find a lot of things in the area of virtualization to be common knowledge.

It is truely astounding how many people still have no idea what virtualization is, let alone having any plans to deploy it in their infrastructure.

VMware have ruled the market in this area for over the past 10-15 years, however they have a serious competitor. Whilst VMware stay put over in the blue corner, not really offering much more than in recent years other than charging their customers through the nose for their solution, over in the red corner, is Red Hat offering a solution that not only significantly outperforms VMware’s products with obscene statistics, but the TCO is also obscenely cheaper than what VMware can offer.
