Hi,

Recap. You have two HDDs:

[1] One 160GB with the OS on so '/'.
[2] Second 1TB.

Correct?

Does [2] get mounted as '/home' or are you using it as a extra data drive? How
are you mounting it in '/etc/fstab'?

You can use the command 'df -h' in the terminal to see mount points.

If [1] is the OS drive as you suggest, the VM HDD is on there. Look at the
screenshot. There is a default pool for VM disk images at
'/var/lib/libvirt/images' and that is where you created the 20GB image.

Regards

Phil
