You must set “user” and “group” to “oneadmin” like described in the
documentation[1].
This way the qemu process run as oneadmin and has write access to the images.
This trick does work to start the particular VM in question
in this particular use case of shared repo and cloning.
I think we didn't make this change in our ONE3.2 installation because
we had other reasons why we needed the qemu user to run KVM

I am trying to allocate a new image in OpenNebula using the

Once the disk is attached, it is up to the guest OS to detect and mount it.
In ubuntu, you can rescan the scsi bus with the command:

You may need to change host0 to other id.

Hello All,
Perhaps I'm misunderstanding how datastores work, but whenever I
instantiate a VM, the whole image is cloned into the default datastore.
I even went as far as creating a user/group, creating a datastore for that

datastore.

Here is how I would do it:
Create a VNet as oneadmin, and grant your users permission to USE it. This
can be done moving the vnet to the user's group (onevnet chgrp), changing
the permissions (onevnet chmod), or using ACL rules (oneacl). See [1] for
more information about all this.
