Those defaults are coming from libosinfo now, hence the change. So if 
installing Fedora, 20GB is the recommended disk size, and I believe that comes 
from official Fedora docs. Of course a smaller disk is possible if you do a 
minimal install and very little

Hmm. The disk image name is supposed to match the name of the VM, and the 
defualt VM name was changed to match the chosen OS. There might be a bug here 
where we don't change the generated disk image name if the user changes the VM 
name from the default. Please file a virt-manager bug, with full steps to 
reproduce, and virt-manager --debug output when reproducing.

It should always suggest to delete the VM disk image. Please file a bug with 
virt-manager --debug output when reproducing, as well as a description of what 
the delete dialog is showing when you try to delete.
