Hi,<div><br></div><div>Just to add a few considerations:</div><div><br></div><div>1.- Save_as images are not created on the datastore, just an ID is generated as a placeholder for the new image (this is the fstype: save_as). So, it is normal that no image (actual path) is created after a save_as operation, and the state is supposed to be locked (waiting for the real image) as reported. I do not see any issue here.</div>
<div><br></div><div>2.- The save_as image is moved to the final destination when the VM is shutdown, shutdown means onevm shutdown (delete or stop will not move the image, for example). Could you send the output vm.log of the image after the shutdown. You should look for messages about a MVDS command.</div>

Hi,<br>
<br>
I'm struggling to understand the situation you are describing. Correct<br>
me if I am wrong.<br>
<br>
You mention dom0. Are you using Xen? If that is true disregard what I<br>
said about changing dynamic_ownership parameter in libvirt as Xen<br>
drivers do not use libvirt for hypervisor communication.<br>
</blockquote></div>
It's kvm image and dynamic_ownership was wrong because I misunderstood and put it to 1, now is 0 and owner and group is not changed.<br>
But option save as still doesn't work, I tried it directly from frontend shell instead SunStone and I got that:<br>

It's not saying where it is creating the image (source in OpenNebula<br>
parlance) and give an strange type. Could you please send us the VM<br>
and Image templates from onevm and oneimage show? Maybe I am missing<br>
something and other developers could help me here.<br>

I also see this line that says the image was created:<br>

But you are telling me that the image does not exist. Are you checking<br>
the hypervisor node or the frontend?<br>
<br>

After delete machine image state is showed as READY in Sunstone.<br>
In dom0 deployment dir and file are still present and disk files disk.0 and<br>
disk.1 have their user and group changed to root.root and image file doesn't<br>
exist<br>
A new file appears<br>

This is really strange. After EPILOG (the state that comes after<br>
successful shutdown, delete or cancel) the VM directory in the system<br>
datastore is deleted, so those files should not be there. Also, then<br>
only way OpeNebula tells Xen to create checkpoint is on SAVE, STOP or<br>
MIGRATE. Are you sure that you have deleted the VM? It looks to me<br>
that the image was suspended or stopped. Bear in mind that save_as is<br>
not done in that state.<br>
<br>

Also with root.root but 666 file permission and in this case directory and<br>
files of this machine are never deleted from running datastore<br>

The non deletion of images is consistent my the SAVE/STOP theory.<br>
