<p class="MsoNormal">I got a problem is I need to delete current instance which contains GPU to release device if I want assign GPU to another new instance temperately.<br>
<br>
I'll got "No valid host was found" if I creating new instance contains GPU flavor without delete present instance, even the instance is shutdown.<o:p></o:p></p>
