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