I like using
vboxmanage for disk conversions. When dealing with major formats it often can do everything I need. For example, if I wanted to convert raw disk image to .vmdk, it’s easy:
vboxmanage convertdd in.raw --format VMDK out.vmdk
However, sometime this simple tool is too simple. For example, using that image with ESXi, any modern version will just give you “
Not a supported disk format (sparse VMDK version too old)“.
But it’s not like
vboxmanage is the only game in town. For example one can use
qemu-img convert -f raw -O vmdk in.raw out.vmdk
Different tool, same error.
For ESXi to work, we need to tweak options a bit.
qemu-img convert -f raw -O vmdk \
-o adapter_type=lsilogic,subformat=streamOptimized,compat6 \
And this one does the trick.
