You aren't giving us much to go on.  Have you looked at the
troubleshooting wiki page, to see if any of those symptoms appear to
match your situation?

http://wiki.libvirt.org/page/Troubleshooting

What versions of libvirt and qemu-kvm do you have installed?  What
command line are you executing when you hit your failure?  Have you
looked for log files, such as /var/log/libvirt/qemu/$dom.log, for clues?

Yes, virt-manager can reuse an existing disk instead of creating new
storage when using it to wire up a domain.  Another idea is to create a
domain using a scratch image location, then use 'virsh edit' and look
for the <disk> designation of that location, and edit it to point
instead to your pre-existing .img file.
