[one-users] Cannot clone persistent image

[Javier Fontan]

>From the log file I'm seeing that you are using shred drivers and I
suppose you are using kvm. Can you check that in
/var/lib/one/var/datastores/1 there are images that belong to oneadmin
and other images which the owner is root?

If this is the case check that your libvirt configuration has
dynamic_ownership set to 0 and the correct user/group [1]:

$ grep -vE '^($|#)' /etc/libvirt/qemu.conf
user = "oneadmin"
group = "oneadmin"
dynamic_ownership = 0
