Hi,
Just to add a few considerations:
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.
Ok, I understood that file was created at that moment.
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.
The complete log for that machine, there is not MVDS message. From onevm
show image was created at REGISTER TIME : 11/27 11:36:26

Hi,
I'm struggling to understand the situation you are describing.
Correct
me if I am wrong.
You mention dom0. Are you using Xen? If that is true disregard
what I
said about changing dynamic_ownership parameter in libvirt as Xen
drivers do not use libvirt for hypervisor communication.
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.
But option save as still doesn't work, I tried it directly from
frontend shell instead SunStone and I got that:

From onevm help I understood that now it's supposed I have the file :
saveas <vmid> <diskid> <img_name>
Sets the specified VM disk to be saved in a new Image. The
Image is
created immediately, but the contents are saved only if
the VM is
shut down gracefully (i.e., using 'onevm shutdown' and not
'onevm delete')
But it does not exist:
[grid@cloud ~]$ file
/var/lib/one/datastores/100/08cee146d8bff43c6c61794f1ba947d3
/var/lib/one/datastores/100/08cee146d8bff43c6c61794f1ba947d3:

After a shutdown file still does not exist but image is marked as
READY

First line I see in the in the log file seems seriously broken:
426622-Mon Nov 26 14:06:42 2012 [ImM][I]: Creating disk at of
2216Mb
(type: save_as)
It's not saying where it is creating the image (source in
OpenNebula
parlance) and give an strange type. Could you please send us
the VM
and Image templates from onevm and oneimage show? Maybe I am
missing
something and other developers could help me here.
I also see this line that says the image was created:
426627:Mon Nov 26 14:06:42 2012 [ImG][D]: Message received: MKFS
SUCCESS 25
/var/lib/one/datastores/100/a3e076f377a855dc76f44ac373c9b0ca
But you are telling me that the image does not exist. Are you
checking
the hypervisor node or the frontend?

After delete machine image state is showed as READY in
Sunstone.
In dom0 deployment dir and file are still present and disk
files disk.0 and
disk.1 have their user and group changed to root.root and
image file doesn't
exist
A new file appears
# file /var/lib/one/datastores/0/123/checkpoint
/var/lib/one/datastores/0/123/checkpoint: data
This is really strange. After EPILOG (the state that comes after
successful shutdown, delete or cancel) the VM directory in the
system
datastore is deleted, so those files should not be there.
Also, then
only way OpeNebula tells Xen to create checkpoint is on SAVE,
STOP or
MIGRATE. Are you sure that you have deleted the VM? It looks to me
that the image was suspended or stopped. Bear in mind that
save_as is
not done in that state.
Also with root.root but 666 file permission and in this
case directory and
files of this machine are never deleted from running datastore
The non deletion of images is consistent my the SAVE/STOP theory.
