What is the best method for setting the virtual hard drive (VDI) of the primary controller for an existing virtual machine?
Does the syntax change if the VDI is really a child differencing disk of some other parent disk? Do you need to attach the parent VDI and then the child VDI in some way?
I have an existing VM --- I want to replace the hard drive it uses to boot - with either another normal virtual HD or possibly a differencing disk. Can this be done with VBoxManage?
