&gt; Hi Jim,<br>
&gt; Thanks for your reply!<br>
&gt;<br>
&gt; I use xm create to create a tap2 disk and it works well<br>
&gt;<br>
&gt; disk = [ &#39;tap2:vhd:/root/tapdisk/vhd-f12,hda,w&#39;]<br>
&gt;<br>
&gt;<br>
&gt; but virsh dumpxml can&#39;t get anything about the disk<br>
&gt;<br>
&gt;<br>
&gt; After i apply the patch, i can catch &lt;disk&gt; information by virsh dumpxml<br>
&gt; but it seems that it only recognize &quot;tap&quot; only but not tap2<br>
&gt;<br>
&gt; &lt;disk type=&#39;file&#39; device=&#39;disk&#39;&gt;<br>
&gt;       &lt;driver name=&#39;tap&#39; type=&#39;vhd&#39;/&gt;<br>
&gt;       &lt;source file=&#39;/root/tapdisk/vhd-f12&#39;/&gt;<br>
&gt;       &lt;target dev=&#39;hda&#39; bus=&#39;ide&#39;/&gt;<br>
&gt; &lt;/disk&gt;<br>
&gt;<br>
&gt; Afterwards i try to use this xml file to virsh create VM  and  no<br>
&gt; active disk is found.<br>
<br>
</div>Opps, I forgot to account for tap2 in functions that generate sexpr.  V2<br>
attached.<br>
<br>
