                   srsName: "EPSG:900913",

You need to find the correct name for the layer you are trying to load. Try a getcapabilities request to the service like so:

http://demo.opengeo.org/geoserver/wfs?request=getcapabilities

Then search for 'countr' to find whether there are any layers with country geometries for you to use.

Edit:

I made a little JSFiddle for the layer. Depending on your connection it might take a little to load the whole of the WFS layer. In my case about 5 seconds.
