Multiple architectures requires either multiple nova-computes with the baremetal driver (each configured for one arch), or Ironic. Windows is not yet a feature for nova-baremetal or Ironic, but we'd love it to be :) Ditto OS X. DNS support in Nova - not sure of the current status but there was a plugin interface at once point where you could query your inventory app. DHCP - you'll need to write a Neutron plugin to override the DHCP allocation policy there.I suspect some refactoring will be needed. Network configuration - model it in Neutron, should be straight forward. > My hope is that we could add plugins that would glue OpenStack to some of the > tools we're already using.

Yes, one OpenStack region can handle multiple baremetal flavours, which seems to be the only variation you have between the machines - client OS is always a separate layer in OpenStack :) -Rob -- Robert Collins <rbtcoll...@hp.com> Distinguished Technologist HP Converged Cloud _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
