Convert VMware .vmdk to KVM .qcow2 or Virtualbox .vdi

May 19th, 2009 by bodhi.zazen

이 문서는  qemu-img 를 이용하여 .vmdk 를 변환하는 것에 대한 내용을 담고 있습니다. 하지만 VMware 3 and 4 이미지 포맷과 호환성 있습니다.

At least that is what Google searching and reading the qemu man pages yielded after I got this error message :

qemu-img convert Ubuntu.vmdk -O qcow2 Ubuntu.qcow
qemu-img: Could not open ‘Ubuntu.qcow’

그리고 더 나쁜 것은 .vmdk가 나뉘어진 multiple 파일이라면 변경하기는 문서를 찾기가 어렵습니다.

이 문서는 Converting을 끝낼 수 있게 도와줄 것입니다.

First convert the .vmdk to a format compatible with qemu-img.

Turns out this can be done with vmware-vdiskmanager.

1. Converting from .vmdk

Use vmware-vdiskmanager to create a copy. This works with a single or multiple disks.

ls
Ubuntu.vmdk
Ubuntu-f001.vmdk
Ubuntu-f002.vmdk
Ubuntu-f003.vmdk ...

vmware-vdiskmanager -r Ubuntu.vmdk -t 0 Ubuntu-copy.vmdk

Note: If you have multiple disks, use Ubuntu.vmdk as well (you do not need to convert each Ubuntu-f001.vmdk).

Note: That is a -t Zero not a capital O. see man vmware-vdiskmanager.

Note: vmware-vdiskmanager is part of vmware server (and workstation, not sure about player).

2. Alternate – Converting “flat files”.

Flat files are used by vmware if you create a virtual disk (vmdk) with the “Allocate all disk space now” option (you have this option when creating disks for use with vmware). Flat files contain all the data from your .vmdk and can (usually) be converted directly.

Notice, flat files can be directly converted to .qcow. If you wish to convert to .vdi (VirtualBox) convert flat to raw.

KVM :

qemu-img convert Ubuntu-flat.vmdk -O qcow2 Ubuntu-copy.qemu

Note: That is a capital O qcow2

RAW (for VirtualBox)

qemu-img convert Ubuntu-copy.vmdk -O qcow2 Ubuntu-copy.qemu

Note: That is a capital O qcow2

3. Boot the image with KVM

kvm -hda Ubuntu-copy.qcow -net nic -net user -m 512

Caveats :

1. If you have vmware-tools installed, you will have mouse integration.
2. If you have vmware-tools installed, the guest desktop may well be larger then the kvm window. You will need to resize the guest display to 800×600 .
3. I could not convert a .vmdk which was using LVM (Fedora).

VirtualBox – Convert to .vdi

1. First use qemu-img to convert the copy .vmdk to raw.

qemu-img convert Ubuntu-copy.vmdk Ubuntu-copy.img

qemu-img with no options will make a raw image. If you prefer you can specify

qemu-img convert Ubuntu-flat.vmdk -O raw Ubuntu-copy.img

2. Then convert the raw image with VBoxManage

VBoxManage convertfromraw – -format VDI Ubuntu-copy.img Ubuntu-copy.vdi

Note: Two – - in front of “format” (Wordpress converts two – - to one long one).

3. Start VirtualBox, make a new machine or add the Ubuntu.vdi to an existing machine.

Caveats :

1. With VMWare-tools installed, Mouse integration did not work (as it did with KVM).
2. The resolution of the guest is also larger then the Virtualbox window.
3. I installed the VirtualBoxAdditions and guest resolution worked well, mouse integration, however, did not.

As always, I hope this helps. Converting usually went smoothly for me however there is the occasional .vmdk I could not convert.
