Exchanging images with VirtualBox / Qemu/KVM / VMWare

To convert a QEMU image for use with VirtualBox, first convert it to raw format, then use VirtualBox's conversion utility to convert and compact it in its native format. Note that the compact command requires the full path to the VirtualBox image, not just the filename.

1.a. RAW->VDI
qemu-img convert -O raw test.qcow2 test.raw
VBoxManage convertdd test.raw test.vdi
VBoxManage modifyvdi /full/path/to/test.vdi compact

1.b. RAW->VDI
VBoxManage convertfromraw -format VDI test.raw test.vdi

2.a. VDI->RAW
VBoxManage internalcommands converttoraw file.vdi file.raw

2.b. VDI->RAW (or any format)
VBoxManage clonehd image.vdi image.raw --format RAW

3. VMDK->RAW
qemu-img convert file.vmdk -O raw file.img

4. RAW->VMDK
qemu-img convert -O vmdk WindowsXP.raw WindowsXP.vmdk

LiveCD / SSH
dd if=/dev/hda | gzip | ssh user@host 'gzip -d | cat > disk.raw'
