I was following this tutorial and got stuck at the point where I was to connect to the libvirtd using SSH. After a looking into this matter a little I found that the SSH service was not active on my machine as default. I just installed the OS right before starting this tutorial. After enabling and starting the SSH service in the services window, I was able to connect. Just thought that you may want to add this as a side note in your tutorial.
