I am on Fedora with KDE (Kinoite) and use virt-manager.
I like to test a lot of stuff, but the VMs are not big. As they are dynamically allocated, I create them with 50GB or something.
But it seems that virt-manager and also KDE Dolphin see these qcow2 images as being full size, so I currently have only 20GB of “space left”.
Do you know anything about this?
My best guess is that you forgot the -f parameter to qemu-img.
Hmm. Maybe? This would be a virt-manager but though, as I stopped bothering with CLI and just use that again
