&gt; 1. Try to see the logs on Storage server for more information. What kind<br>
&gt; of<br>
&gt; errors you are getting?<br>

&gt;&gt; Thanks for the answer.<br>
&gt;&gt; &gt; I&#39;m not an expert on this, but here is what I would try:<br>
&gt;&gt; &gt;<br>
&gt;&gt; &gt; 1. Are you using the latest virtio drivers on your Windows guest(s)?<br>
&gt;&gt; &gt;      <a href="http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/" target="_blank">http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/</a><br>
&gt;&gt; Yes, this version is used<br>
&gt;&gt;<br>
&gt;&gt; &gt; 2. Is there any particular reason you use CentOS 6.4 on your storage<br>
&gt;&gt; &gt; server?<br>
&gt;&gt; &gt;      I would update it to CentOS 6.5 so you would have matching Linux<br>
&gt;&gt; &gt; kernels on both of your systems.<br>
&gt;&gt;<br>
&gt;&gt; OK, will try and schedule the maintenance, but when it was 6.4<br>
&gt;&gt; everywhere<br>
&gt;&gt; - all was the same.<br>
&gt;&gt;<br>
