It seems that openstack/devstack is capable of orchestration of such a heterogeneous system and could be customized according to the specific needs. I, however, am experiencing a lot of issues when including the resources e.g. when i try to create an ubuntu image and launch it, it results in errors that are quite complex to resolve and so i intend to reach out to the experts so as to resolve these issues at hand. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p><o:p> </o:p></p><p>Regards<o:p></o:p></p><p><o:p> </o:p></p><p><o:p> </o:p></p></div></body></html>
