Ubuntu didn't used the whole disk while installation

Question

I'm using Ubuntu 20.04 LTS "Focal" with ppc64le architecture (mage was: http://cdimage.ubuntu.com/releases/focal/release/ubuntu-20.04.5-live-server-ppc64el.iso) in a qemu virtual machine with an Debian 11 (AMD64) as host. The VM has a 25GB emulated hard disk. But the guest only shows me round about 12GB.

Why?

I didn't increased the size of the virtual hard disk. It was 25GB from the beginning when I installed Ubuntu on it. I don't understand why Ubuntu didn't used the whole disk. I didn't modified the default values of the installer.

I need to increase the swapfile on hard disk.

Does this answer your question? How do I enlarge an encrypted LVM partition in Ubuntu 20.04? — guiverc, Oct 04 '22 at 08:15
No, sorry. Because I haven't increased my disk. The problem here is that Ubuntu didn't used the whole 25GB while installing and I don't understand why. — buhtz, Oct 04 '22 at 08:22
"I need to increase the swapfile on hard disk." Does this answer your question? Increase swap in 20.04 — graham, Oct 04 '22 at 09:48
No it did not. I know how to increase swap. But I can't because there is no much space on the disk available because Ubuntu us only 12 GB of 25. — buhtz, Oct 04 '22 at 10:07
Please edit your question to include the output of lsblk in your Ubuntu VM. — Tilman, Oct 04 '22 at 10:14
sudo lvresize -l +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv did not work. "No free space left" I didn't tried the partitionmanager because no X installed and no live CD available. — buhtz, Oct 04 '22 at 11:18
