Further still!

[root@pp-xen-dev ~]# TMPLUUID=$(xe template-list | grep -B1
'name-label.*Red Hat.* 6.*64-bit' | awk -F: '/uuid/{print $2}'| tr -d "
")
[root@pp-xen-dev ~]# VMUUID=$(xe vm-install new-name-label="CentOS6"
template=${TMPLUUID})
The SR has no attached PBDs

[root@pp-xen-dev ~]# virsh pool-info Ceph

[root@pp-xen-dev ~]# xe sr-list

    name-description ( RW):

                type ( RO): libvirt
        content-type ( RO): 

So close!  Any help, please, I don't know what that error means; "The SR
has no attached PBDs".
