hi,all<div><br></div><div>I use Java api `domain.attachDeviceFlags(xml, 0);` to add a disk for domain. the xml file like this:</div><div><br></div><div><div> &lt;disk type=&#39;file&#39; device=&#39;disk&#39;&gt;</div><div>
      &lt;driver name=&#39;qemu&#39; type=&#39;raw&#39;/&gt;</div><div>      &lt;source file=&#39;/dev/sp1353486595267/v1353488096262&#39;/&gt;</div><div>      &lt;target dev=&#39;vdb&#39; bus=&#39;virtio&#39;/&gt;</div><div>
    &lt;/disk&gt;</div></div><div><br></div><div>then I use  command `virsh detach-disk $domain vdb` to remove the disk.</div><div><br></div><div>what  I said above have no any errors.but the problem is when I restart this vm ,the  disk still exist,because I see it from the command `virsh dumpxml $domain` ,how to remove the disk from this domain persistently.</div>
<div><br></div><div>thanks in advance.</div><div><br></div><div>&gt;zhijun</div><div><br></div>
