Subject [jira] [Commented] (CLOUDSTACK-6825) [Automation] Create template from snapshot fails with NPE in KVM
Date Wed, 11 Jun 2014 22:55:02 GMT

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-6825?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14028538#comment-14028538
] 

Min Chen commented on CLOUDSTACK-6825:
--------------------------------------

Just looked at automation setup with Rayees, CLOUDSTACK-6825 is not really
an issue of createTemplateFromSnapshot, the real issue is that the
snapshot passed to createTemplate command has its owner removed in DB,
thus causing checkAccess failure. As for why the snapshot is still not
removed when the account is removed on automation setup, that should be a
different issue.
