Hi Carlos,
I appreciate the security issues. I'm just wondering why
/var/lib/one/datastores is not a safe directory by default given it is
the default location for datastores?
Regards,
Gerry

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.

Hi,
This seems to be a general issue not specific to QCOW2. For the moment
I've solved the issue by mounting the datastores (which are NFS exports for
a filestore) on the root partition at /datastores and created a symlink
form /var/lib/one/datatstore to /datastores.
Is this correct?

Hi,
I get the following error when trying to create an image from a QCOW2
file: "Error copying image in the datastore: Not allowed to copy image
file /var/lib/one/datastores/1/**DELETEME.qcow2"
Below are the commands I use to create the QCOW2 file before trying
to create the image named DELETEME using oneimage. The QCOW2 file is has
been created with a backing file.
This used to work in Opennebula 3. I have made sure the use oneadmin
is also in the cloud group in case it is some kind of permissions file.
Any ideas?

Gerry
