I just tried adding -vvv to the ssh command, and it's hanging on: "Debug1: Connecting to (remote_IP) port 22." So I also tried adding a wget into rc.local, and wget fails with: "Resolving download.fedora.redhat.com... Failed: Host not found." So my guess is that Xen isn't bringing up the network for the VM until after login.
