Just a heads up for those of you that use KVM and the wonderful kvm (83) SlackBuilds script. The current script will not work with version 85 even after you update the kvm.SlackBuild script from version 83 to 85.
The maintainers of KVM have permanently removed the kvm python script from the tar.gz distribution which is used by the kvm (83) SlackBuild script in the following line:
cp -a kvm scripts $PKG/usr/doc/$PRGNAM-$VERSION/
It's documented in the kvm changelog and I verified it on the Freenode kvm IRC channel.
My dirty solution was to add the kvm-84 version of the kvm python script back into the kvm-85.tar.gz. I'm not skilled enough to change the kvm.SlackBuild script but I did send an email to the script maintainer.
Hope this helps others until the scripts are updated.
