<div>Hi everyone,</div>
<div><br>
</div>
<div>Whenever I try to launch an image instance beyond 'micro' (anything that has more than 0 GB disk space) I get the "no valid host found" error, even though my disk has 100+ GB of space, even displayed in the dashboard.</div>
<div><br>
</div>
<div>The error in the nova scheduler says "Flavor's disk is too small for requested image." Any suggestions as to what I should try or what may be happening?</div>
<div><br>
</div>
<div>FYI I'm running a DevStack based install of OpenStack.</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Mark</div>
<br>
