Hi Carlos.<br>
<br>
Very strange: After running ttylinux and enabling the saveas-feature
('onevm saveas 318 0 "318_archived"') I get the following error
message (vm.log) after deleting this instance:<br>
Thu Feb 10 12:24:31 2011 [VMM][W]: Ignored: CANCEL SUCCESS 318
Domain one-318 destroyed<br>
Thu Feb 10 12:24:31 2011 [HKM][I]: Command execution fail:
/srv/cloud/one/share/hooks/image.rb 318<br>
Thu Feb 10 12:24:31 2011 [HKM][I]: STDERR follows.<br>
Thu Feb 10 12:24:31 2011 [HKM][I]: ExitCode: 255<br>
Thu Feb 10 12:24:31 2011 [HKM][E]: Error executing Hook: image.<br>
<br>
After debugging $ONE_LOCATION/share/hooks/image.rb there might be a
problem with the proper image location:<br>
line 75 in $ONE_LOCATION/share/hooks/image.rb (result =
img_repo.update_source(image, source_path) outputs<br>
"No such file or directory - /srv/cloud/one/var/318/disk.0 or
/srv/cloud/one/var//images/7c6f81fcb5b4dec12ab3fa63913b16b4ba1e2d12"<br>
<br>
All disk images of my vm's are deployed to
$ONE_LOCATION/var/<vm_id>/images/<br>
If I get the error message right, it tries to lookup for the disks
in $ONE_LOCATION/var/<vm_id>/<br>
<br>
I need your help. Can that be right? <br>
<br>
(detailed logs see below)<br>
<br>
<br>
Thanks in advance<br>
Marco<br>

Hi.<br>
<br>
Thanks Carlos! I have managed to reproduce the behaviour by xmlrpc
calls.<br>
But for the long term it would be very handy to access the
"saveas" feature in one single xmlrpc call too so that it won't be
necessary to duplicate (onevm ruby) source code and validate it
for each new Opennebula release.<br>
<br>
<br>
regards<br>
Marco<br>

<div>The XML-RPC call requests an image id because the image has

<div>You can check how it is done in the oneimage command (it's
a straight forward ruby script), and then replicate the same

<br>
What is the best way to map the "onevm saveas" command [1]
to OCCI or<br>
XMLRPC-Request? I need to save vm images but want to avoid
using the<br>
command line interface.<br>
<br>
I cannot simply use the xmlrpc-call "one.vm.savedisk" [2]
since I then<br>
would need to know the "image id where the disk will be
saved". But this<br>
ID will be dynamically created by the "onevm saveas"
command, right?<br>
Furthermore where should I place the <image_name> in
the XMLRPC-call?<br>
The same problem with OCCI: Are there any attributes
(perhaps for the<br>
<CONTEXTUALISATION> section) I can use for the
"onevm saveas"?<br>
<br>
<br>
<br>
Thanks<br>
Marco<br>
