qemu-img, virt-resize, and guestfish. It depends on whether you're shrinking or growing which you use and in what order. All of it can be done from the host using qemu-img and guestfish, without the VM being online. And guestfish can resize (well, delete then add) MBR and GPT partitions, resize LVs, and at least the three major filesystems. For sure the VM needs to be off when using guestfish.
Of course, you could boot the VM from some other image, and use the tools you're familiar with from inside the VM. For growing, it's possible to do this online even without booting from some other image, but it'll take one early reboot after changing the last partition size, or adding another partition, to capture the extra space from qemu-img resize.

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.
