[one-users] Images from Images (Ceph) Datastore Not Deploying

A couple of things:
* You shouldn't need the port, that should be generated
appropriately
* I'm not seeing your secret definition within the deployment.0
file. That must exist if using the newer versions of Libvirt w/CephX
authentication (Libvirt assumes if you are specifying hosts that a secret
should be there). You should have an entry in that file like so (right
after the </source>):
<auth username='libvirt'>
<secret type='ceph'
uuid='ebc9c744-016d-40af-ae73-621f558398f0'/>
</auth>
* You've defined the secret/user on the Datastore within
OpenNebula using the appropriate configuration attributes CEPH_HOST,
CEPH_USER, and CEPH_SECRET?
o And also defined the appropriate secret in Libvirt within each
hypervisor in your configuration?
Outside of verifying the above, I'm not sure what else can be attempted.
You could try disabling CephX authentication, removing the CEPH_HOST
configuration attributes, and copying the /etc/ceph/ceph.conf and admin
keyring to each hypervisor and see if you can connect that way (however
newer versions of libvirt will probably prevent that from happening).

Hi Ruben,
So I've been trying to experiment a bit. I started over. Re-imported
ttylinux into ceph datastore. Created new template and new vm and I
logged in as oneadmin and defined the secret as instructed on all hosts.
In creating the new VM, the process failed as before.
I tried as you suggested:
[oneadmin at cloud2 54]$ virsh create -c qemu:///system deployment.0
error: unexpected data 'qemu:///system'
But as you can see I got an error message I'm not sure what to do with.
Also, I have a new log that looks different -- seems adding the port to
the CEPH_HOST was the distinguishing factor.

Hi
I've tested with the very same environment and it should work. Could you
try to define the secret with the oneadmin account and:
-c qemu:///system
option for virsh command.
Also to manually test it, once the vm is in failed state go to the vm
directory in the host and simply execute:
virsh create -c qemu:///system deployment.0
Cheers

Hi Bill,

Also, Ruben -- how do I:
"1.- could you try manually to add port to the <source attribute, and
check if the VM boots with virsh create"
Thank you,

Are you using CentOS/RHEL? Are you using CephX Authentication?
There have been a few changes in how Libvirt handles the configurations of
Ceph images, and I'm not sure if that version of Qemu is compiled with RBD
support.

Well
The deployment file seems to be properly generated, so given the error
message complaining about the missing port:
1.- could you try manually to add port to the <source attribute, and check
if the VM boots with virsh create
2.- I've not seen this required by ceph, here it is working with the
libvirt packages from the ceph guys (libvirt 0.10.2 and qemu-kvm-0.12.1),
Could it be a version problem?
Cheers

Hi
Could you send /var/lib/one//datastores/125/32/deployment.0? Also could
you double check you ceph datastore configuration, specially the CEPH_HOST
attribute to read something like
CEPH_HOST="cephmon1:6789 cephmon2:6789"
Cheers

Hi,
I've added successfully images from the marketplace to the default image

I've continued to add a Ceph datastore and retrieved an image from
