This question is outside the scope of OpenStack itself, unless you're using another OpenStack deployment to manage the physical servers (for example TripleO has an "undercloud" which uses Ironic to manage the servers which then comprise the "overcloud" presented to users). OpenStack's services start on already booted servers, so you can in theory use any mechanism you like, including PXEboot, to boot those physical servers. I understand OpenStack Ironic is a great solution to this problem though, and can be set up entirely stand-alone with its Bifrost installer. -- Jeremy Stanley
