README: "Red Hat and derivatives" and ruby-libvirt

[fxkr]

There's an error in the README

ruby-libvirt is called rubygem-ruby-libvirt in (at least) Fedora 23+

https://admin.fedoraproject.org/pkgdb/package/rpms/rubygem-ruby-libvirt/

[fxkr]

Additionally, it needs a some development tools. @development-tools should do it, but installs 24 packages, not all of which are needed for the "vagrant plugin install vagrant-mutate"

If you know what works for Fedora, please submit a PR that corrects the README.

Ok, will do. It will have to wait till next week though; I was trying to help a colleague get it up and running, it wasn't my machine (trying to get our department to introduce vagrant+ansible), but I have a private appointment and need to leave (its Friday 19:00 in my timezone).

Sorry; I thought it'd be just this one issue; I should have waited with opening an issue until I had a successful vagrant-mutate installation.

So running these commands:

docker run --rm -it fedora:latest /bin/sh
dnf install vagrant-libvirt qemu-img libvirt-devel rubygem-ruby-libvirt ruby-devel -y && vagrant plugin install vagrant-mutate && vagrant mutate http://files.vagrantup.com/precise32.box libvirt

it works fine
