Hi,<div><br></div><div>The VMs themselves are not deleted, just moved to the DONE state. You can still execute a onevm show <id> and see the information of deleted VMs. To be consistent with this, we also leave the directories and log files (note that the disks and checkpoint files are stored in the system datastore).</div>
<div><br></div><div><br></div><div>About the Image, looks like the DB got corrupted. Did you have any problem with your front-end machine, like a full disk, or hard reset?</div><div>Anyway, to change the RUNNING_VMS attribute manually you need to:</div>
<div>- stop opennebula: one stop</div><div><br></div><div>- get the body column of your image from the DB. Assuming you use sqlite:</div><div>$ sqlite3 /var/lib/one/one.db "select body from image_pool where oid=<id>;"</div>
<div>Copy the text, and change the running vms xml element:</div><div><RUNNING_VMS>0</RUNNING_VMS></div><div><br></div><div>- update the DB</div><div> $ sqlite3 /var/lib/one/one.db 'update image_pool set body="<IMAGE>........</IMAGE>" where oid=<id>;'</div>
<div><br></div><div><br></div><div>Restart opennebula, and then you should be able to delete the Image</div><div><br></div><div>Regards</div><div>

Hello,<br>
<br>
my hard drive is running out of space. So i deleted some unused images in Opennebula via the sunstone gui.<br>
But i didn't get any additional free hard drive space. But the datastore contains only files with hash names.<br>
Why happen this? Is this a bug or a feature?<br>
<br>
Regards,<br>
<br>
Christoph Robbert<br>
