[one-users] oneimage QCOW2 problem: Error copying image in the datastore: Not allowed to copy image file

Wed Sep 11 03:51:17 PDT 2013

Hi,

Tue Sep 10 14:32:48 2013 [ImM][E]: cp: Not allowed to copy images from
> /var/lib/one/ /etc/one/ /var/lib/one/

The dir /var/lib/one is a restricted dir, and OpenNebula won't allow you to
copy images from there. Otherwise, you could copy the DB or other
authentication files. That's why it works from /datastores.

See [1] for more information.

Best regards.
