I am just running up a wall trying to figure this out.
I tried to follow this video, but I am not getting any success.
I don't know why, but I initially setup a VM to use 500GB. I only need about 100GB, so I ran GParted as live, reduced my ~500GB partition down to 100GB. I then went into the Unraid command line and ran `qemu-img resize --shrink vdisk1.img 150GB` to be safe. The image resized, but when I go to run the VM I get into the BusyBox terminal. The log doesn't seem to be saying anything is wrong, but I can post that if it would help.
Am I missing something? The image is just a standard 20.04 Ubuntu desktop.
