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.
qemu-img convert -f vmdk disk-image.vmdk -O raw disk-image.img
