Hello. Can you export an image or template from version 4.12 to be used in another OpenNebula version 4.14.2? If qcow2 is a file type with Windows 7, you already have all necessary drivers … Thanks.
You can obtain the actual path to the file by running this in the CLI:
oneimage show <ID>|grep ^SOURCE.
You will need to grab that path and export it manually, using linux, not OpenNebula.
By the way, in OpenNebula 5.0 we are including this functionality:
