There are countless guides and SO questions related to this question, but as far as I can find, they all use a GUI for at least some part of the answer.
I have an Ubuntu 14.4 server, to which I only have SSH access. I use this Ubuntu 14.04 as host to run a Ubuntu 12.04 guest. As such, I only use the command line for both the guest and host.
The guest is running out of disk space, and as such I whish to increase the current 200gb to 400gb.
VBoxManage modifyhd /data_nfs/VM/Ubuntu.vdi --resize 400000
Increasing the vdi size is easy, but for the next steps, I can only find instructions on how to do it using a GUI, like in this question. How can I do this from the command line?
