libvirt on ceph - external snapshots?

    Hello all,
      I have a  VM system with libvirt/KVM on top of  a ceph storage
        system

      
      I can't take an external snapshot (disk + RAM) of a running vm.
        The option view->snapshots is disabled on the virt-manager
        application . On other VM, on the same hypervisor, that runs on
        local storage, I can take snapshots  on virt-manager
      Is it possible to do external snapshots with libvirt/KVM on top
        of  a ceph storage system? How to configure?
      Here is an example of a running VM (output from "libvirt
        dumpxml x"):

      
        .........

        
            <disk type='network' device='disk'>

              <driver name='qemu' type='raw' cache='none'
        discard='unmap'/>

        .........

              <source protocol='rbd'
        name='ostack_volumes/volume-ed46b7c7-676d-40a3-9c22-a4c90fbe294c'>

        .............

      
      thanks for any insight!
      best regards
      João
