If folks are going to use the virt* tools to install f8test2 guests,
something has to change.

I don't know what you tested, but dom0's running 7.90 and earlier will not
be able to install 7.91 guests because 7.91 renamed the Fedora directory to
Packages in the iso.

>From python-virtinst-0.200.0-3.fc7: 
/usr/lib/python2.5/site-packages/virtinst/DistroManager.py:
# Fedora distro check
class FedoraImageStore(RedHatImageStore):
    def isValidStore(self, fetcher, progresscb):
        if fetcher.hasFile("Fedora", progresscb):
            logging.debug("Detected a Fedora distro")
            return True
        return False

If you're going to change the layout of distro in the iso, you're going to
either need to make a symbolic link from /Fedora to /Packages in the iso,
release new versions of python-virtinst for earlier versions of Fedora and
RHEL so that they recognize the new layout, or some other scheme in
python-virtinst to reliably identify the Fedora distro.

Changing line 213 of

/usr/lib/python2.5/site-packages/virtinst/DistroManager.py

from 

if fetcher.hasFile("Fedora", progresscb):

to

if fetcher.hasFile("Packages", progresscb):

And rerunning virt-install or virt-manager for a F8test2 guest now lets the
installer start up.

Do I need to submit a bug?
