A set of homebrew formulae to install virt-manager and virt-viewer on Mac OSX.
Forked from jeffreywildman.
brew tap roeme/homebrew-virt-manager
brew install virt-manager virt-viewer
virt-manager -c test:///default
This fork is for my personal use and shared here for others to waste less time in getting the software up and running. That being said, I don't have the resources available for general user support. While I gladly accept PR's that solve problems that I encounter personally or are reproduced trivially within the confines of my setup, I cannot do this for anything else (upstream issues, for example). If you encounter an issue that is not dependent on your setup, it's likely that I have so as well or will soon. Then, the issue will be fixed.
Your google-fu is weak: That's an known issue, they've been migrated to homebrew-core. Uninstall osinfo-db & osinfo-db-tools, and either reinstall virt-manager or switch to one of the many forks of this formula.
