Hi!

So I actually chose the smallest/defaut size and that was a mistake. Now
I need to increase the size which I did through the GUI, but of course
the OS (GNU/Linux) doesn't see it. I do not want to delete the disk and
make a bigger one as I don't want to reinstall. I think the fs type is
ext4 but I went through automatic install and didn't pay attention...

I couldn't find out how to reboot for the iso file an already installed VM.

Thank you if you could tell me more.
