Description:

def migrate_non_shared(vm_, target, ssh=False):
    '''
    Attempt to execute non-shared storage "all" migration

    :param vm_: domain name
    :param target: target libvirt host name
    :param ssh: True to connect over ssh

    CLI Example:

    .. code-block:: bash

        salt '*' virt.migrate_non_shared <vm name> <target hypervisor>

    A tunnel data migration can be performed by setting this in the
    configuration:

    .. code-block:: yaml

        virt:
            tunnel: True
