When listing instances in the cellv2 world we look them up from three locations: 1. Build requests which exist before the instances are created in the cell database (after the scheduler picks a host to build the instance). Currently instances and build requests are both created before casting to conductor, but that's going away in Ocata with the support for multiple cellsv2 cells. 2. The cell0 database for instances which failed to get scheduled to a compute host (and therefore a cell). 3. The actual cell database that the instance lives in. Currently that's only a single traditional nova database, but could be one of multiple cellsv2 cells when we add that support in Ocata. If a marker is passed in when listing instances, if the instance lives in an actual cell database, we'll get a MarkerNotFound failure from cell0 because the instance doesn't exist in cell0, but we check cell0 before we check the cell database. This makes the instance listing short-circuit and fail with a 400 from the REST API. This patch simply handles the MarkerNotFound when listing instances from the cell0 database and ignores it so we can continue onto the cell database.
