Hmm, not sure why it is trying to use /home/var/libvirt/images/ as the root
directory, Fedora doesn't do that.

Since the initial install didn't work, that disk image is completely blank,
and doing an import install will not work because the disk has nothing to boot.

You want to do a CDROM install, select the ISO like before, on the storage
page, type the path into the box: /home/var/libvirt/images/test.img   and
continue on, choosing br0 as your bridge device.
