Hi.
So, the problem here is a couple of things.
First: libvirt doesn't handle RBD storage pools without auth. That's my
bad, but I never resolved that bug: http://tracker.ceph.com/issues/3493
For now, make sure cephx is enabled.
Also, the commands you are using don't seem to be right.
It should be:
$ virsh secret-set-value $(cat uuid) <base64 secret key>
Could you try again with cephx enabled and setting the secret value like
mentioned above?

Hi Dave, Thank you so much for getting back to me.
the command returns the same errors:
[root@xen02 ~]# virsh pool-create ceph.xml
error: Failed to create pool from ceph.xml
error: Invalid secret: virSecretFree
[root@xen02 ~]#
the secret was precreated for the user admin that I use elsewhere with
no issues (rbd mount, cephfs etc.), and per the ceph documentation, i
just set the secret value with this command
virsh secret-set-value $(cat uuid) --base64 $(cat client.admin.key)
where the key is obtained from
ceph auth list
and uuid is generated by
virsh secret-define --file secret.xml
# cat secret.xml
<secret ephemeral='no' private='no'>
<usage type='ceph'>
<name>client.admin $(cat client.admin.key)</name>
</usage>
</secret>

I must confess that I've disabled auth in my test environment.
Clearly I should
go back and enable it again :-)

The "xe sr-create" call is handled by "xapi" which calls
"xapi-libvirt-storage" which
uses the libvirt API directly to create the pool. It _should_ do the
same as running
virsh pool-create ceph.xml
Could you try the "virsh pool-create" and see if that works? If it
does, then we need
to figure out what the "virsh" CLI is doing that my Pool.create
function call isn't. If
it doesn't then there might be some other missing step. Did you have
to pre-create
a secret (is that "virsh secret-create"?)
Cheers,
Dave Scott
