On network attached volumes in which the qemu process directly access the device over the network, this device_path attribute does not exist that leads to an exception. https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L1636 ... state = guest.get_power_state(self._host) active_state = state in (power_state.RUNNING, power_state.PAUSED) if active_state: disk_path = connection_info['data']['device_path'] <===== LOG.debug('resizing block device %(dev)s to %(size)u kb', {'dev': disk_path, 'size': new_size}) dev = guest.get_block_device(disk_path) ...
