CirrOS 0.4.0 image in glance and 3.6 compatibility

Hi, when I run OST basic-suite-master with DC/cluster version 3.6, import_template_from_glance fails with the following error: RequestError: status: 400 reason: Bad Request detail: Cannot import Virtual Disk. QCOW2 compat version is not supported for Data Center version. When I use the former CirrOS 0.3.4 image instead, it works fine. Would it be possible to provide CirrOS 0.4.0 glance image compatible with 3.6 DC/cluster version, until we stop supporting (i.e. testing) it? Thanks, Milan
