OpenNebula will clone any non-persistent images, (that is the way to keep the image untouched). But you need to clone a persistent image, right? Why not changing the image to non-persistent then?. If you need to clone but preserve the changes you can save_as the image, or maybe stop / resume the VM.</div>
<div><br></div><div>Or, do you want to implement an special semantics for the clone operation? </div><div><br></div><div>Or maybe you want to take a template using an image, copy that image make it persistent and create a VM using the original VM but with the copied image? Something like (assuming img and tmpl are the image and template you are interested in):</div>
<div><br></div><div>#clone image</div><div>oneimage clone img new_img</div><div><br></div><div>#clone the the template</div><div>onetemplate clone tmpl new_tmpl</div><div><br></div>
<div>#change base disk in the new_tmpl, hakish I know </div><div> EDITOR="sed -i 's/IMAGE=\"img\"/IMAGE=\"new_img\"/g'"<br></div><div>onetemplate update new_tmpl</div>
<div><br></div><div>#instantiantiage the new tmpl</div><div>onetemplate instantiate new_tmpl</div><div><br></div><div>Hope it helps ....</div><div><br></div><div>Cheers</div><div>
