It's a simple process that consists of cloning the
vmdk file, formatting it to
vdi, resizing it, and then cloning it back to
vmdk (if that's the type you want to keep). I ended up keeping the
Run the following commands in the folder that contains the
vmdk file you want to resize. Assuming you want to resize to 70GB (70 * 1024)
VBoxManage clonehd "myfile.vmdk" "cloned.vdi" --format vdi VBoxManage modifyhd "cloned.vdi" --resize 71680 VBoxManage clonehd "cloned.vdi" "final.vmdk" --format vmdk
At this point you will want to attach "final.vmdk" to your VM. If you're running a Windows VM you will still need to resize the drive to take advantage of the new allocated space. Start your VM and go to "Disk Management" (on Windows 10 just right click on the Start logo and select Disk Management from the list). Right-click on the drive you want to resize (in my case it is "C:") and choose "Extend Volume". Follow the prompts and you're done.
