Hi Carlos,<div>Thanks a ton for all this information.</div><div>From the onevm saveas code, I have identified that a new image has to be allocated before it can be used to save a running VMs disk image. So I need to create a new virtual image before I can call the savedisk method on the VM by using the new image id.</div>
<div><br></div><div>Thanks,</div><div>Prakhar<br><br><div class="gmail_quote">2011/4/28 Carlos Martín Sánchez <span dir="ltr"><<a href="mailto:cmartin@opennebula.org">cmartin@opennebula.org</a>></span><br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
Hi Prakhar,<br><br>The Java OCA is a wrapper for the XML-RPC interface [1].<br>The image file manipulation done by the oneimage command is performed by the ImageRepository.rb [2] utility. You can take a look at the code to get an idea of the steps. Or even check this thread [3].<br>
<br>Your Java application has to be aware of that, and perform the same file operations, as described in [4].<br><br>Regards,<br>Carlos.<br><br>[1] <a href="http://opennebula.org/documentation:rel2.2:api" target="_blank">http://opennebula.org/documentation:rel2.2:api</a><br>

Hi,<div>When I run the command,</div><div> onevm saves VMID DISKID IMAGENAME</div><div>the image of the disk is successfully saved upon shutdown of the VM, however the the file with a hash string name in (/srv/cloud/one/var/images) is not created.
