    qemu/rbd: improve rbd device specification · 5745dc12
    Sage Weil 提交于
    This improves the support for qemu rbd devices by adding support for a few
    key features (e.g., authentication) and cleaning up the way in which
    rbd configuration options are passed to qemu.
    
    An <auth> member of the disk source xml specifies how librbd should
    authenticate. The username attribute is the Ceph/RBD user to authenticate as.
    The usage or uuid attributes specify which secret to use. Usage is an
    arbitrary identifier local to libvirt.
    
    The old RBD support relied on setting an environment variable to
    communicate information to qemu/librbd.  Instead, pass those options
    explicitly to qemu.  Update the qemu argument parsing and tests
    accordingly.
