Thanks for this. Patches look fine to me minus some minor comments.

Though when I run this on stock f20, which seems to have libosinfo-0.2.8,
virt-manager just segfaults. I think it will be quite common for a while that
people try to run upstream virt-manager but won't have the latest required
libosinfo version on their machine. Can you add a check somewhere that will
detect if libosinfo isn't new enough, and provide a helpful message to the
user, then gracefully exit?

Also, we can probably drop the 'virt-install --os-variant list' handling, and
point man page/help output to whatever the libosinfo equivalent is.

So, plan for applying this. I want to get a new virt-manager release out
before mid February, and I'd like to hold off on applying these till after the
new release. Reason being is that a new enough libosinfo doesn't even exist
yet, so I want to give that some time to propagate, and at least exist in
fedora rawhide. And then we can have more time to try and take advantage of
the other libosinfo goodies for the follow up release.

So let's claim virt-manager.git osdict.py as officially fossilized, no new
changes will be applied there. And if you can find out when the next libosinfo
release is, and possibly nudge it sooner rather than later, thatll help too.
Once the new virt-manager release goes out, and libosinfo is released, we can
apply these patches to git and go from there.

Thoughts?

Thanks,
Cole
