What am I doing wrong ? The background doesn't set properly.
<svg version="1.1" id="Layer_2" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
width="1101px" height="617px" viewBox="0 0 1101 617" enable-background="new 0 0 1101 617" xml:space="preserve">
<defs>
<pattern id="image" patternUnits="userSpaceOnUse" height="150" width="150">
<image x="30" y="0" height="150" width="150" xlink:href="http://i.imgur.com/7Nlcay7.jpg"></image>
</pattern>
</defs>
<circle fill="url(#image)" stroke="#676467" stroke-width="3" stroke-miterlimit="10" cx="186.051" cy="489.94" r="63.29"/>
</svg>
