This formula for `virt-manager` does not include the `openssh-askpass` dependency and does not prompt for passwords in a popup window. Here are two workarounds:
1. Run `virt-manager` with either the `--debug` or `--no-fork` option to get password prompt via the CLI.
2. Set up SSH keys between your local and remote system to avoid the prompt.
#### Why can't I connect to a local URI (*e.g.*, qemu:///system)?
I've not yet tested `virt-manager` against any local URIs/hypervisors. If you get `virt-manager` working with a local hypervisor and needed to take any special steps, feel free to share the details.
#### Everything was working yesterday, but it's not working today, can you help?
If `virt-manager` or its dependencies have been upgraded recently (`brew upgrade`), it's possible that a reinstall may fix the issue (see [#39](https://github.com/jeffreywildman/homebrew-virt-manager/issues/39)).
