There's no real 'right' answer here, but I'd recommend 1. really.
There might not be a right answer but 1 is definitely a wrong answer.
Changing /etc/libvirt/storage/default.xml to point to a directory in a
separate partition with lost of free space was easy. However, when I tried to
create a new guest using virt-manager and the creation "wizard", for the disk
image, it still showed the free space available in the root partition (8GB)
rather than that of the other partition (120GB),
So I resorted to 2 which appears to work OK.
My current thinking is to use option 3 ultimately. That way, I can get things
configured when I install a new system.
If you believe that option 1 should work then there appears to be a bug.
Please clarify. If there is a bug, I will bugzilla it.
