I have virtualbox-4.1.0 with centos-5.6 installed in. Now I would like to extend the VM image, which I previously allocated for virtual machine installation, it was 8Gb, that\'s
At some point the VBoxManage utility changed the syntax a little bit. It's worth noting that this doesn't work on all vm types so beware if you have a *.vmdk. An example command to change your HD to 40GB is:
$ VBoxManage modifyhd MyVirtualImage --resize 40960
For reference I am on VirtualBox 4.2.1, Mac 10.8.2
