I just did a fresh F19 x86_64 install on my workstation, copied a

Now I would like to be able to ssh into the VM from another box on my

So how do I make firewalld allow pings and ssh from remote hosts?
For the archive:
In Fedora's default configuration, there is one virtual network for
hosts in a NAT configuration. In that configuration, you cannot achieve
what you asked. There's no way to allow PING to the internal hosts.
You *can* allow SSH, but only by forwarding specific ports.
There are other supported network configurations for libvirt. In
addition to NAT networks, you can have routed or bridged networks:
http://wiki.libvirt.org/page/VirtualNetworking#Examples_of_common_scenarios
In a routed network, the firewall configuration should be pretty
straightforward, but you'd need to add a route to the guest network at
every remote host, or at the router that they share.
In a bridged network, guests are on the same LAN as the host and
normally aren't subject to the host's firewall rules:

Bridged networking is the most straightforward configuration if you want
remote access to your guests.
