Thanks for your reply,

everything is ok on my side.
virsh -c qemu:///system list --all
show only our test vm not opennebula vm.

and as root :

grep -i oneadmin -r /etc/libvirt/*
/etc/libvirt/qemu.conf:user = "oneadmin"
/etc/libvirt/qemu.conf:group = "oneadmin"

I’ve checked the deployment.x file in /var/lib/one/datastore/100/6
I see that no information about ceph auth like:

<auth username='libvirt'>
        <secret type='ceph' uuid='47961330-cd81-458e-a426-c6dec192f0f1'/>
</auth>

I had this information on the datastore ceph, and it’s present on the file ds.xml.
I’ve always the same message:

I don’t understand the message: XPath set is empty

We’ve succeeded to create vm manually using ceph disk on the host.

Thanks for your help
