[Rdo-list] http server problem with openstack

I installed *openstack --allinone* on one computer (Say A). Then, I added two more compute nodes(Say B and C) on this. Everything is working fine. But now, for some other reason I want to start HTTPServer on computer B and access it from computer X and Y which are different from A,B & C. Now after running HTTPServer on computer B, I'm not able to access it from computer X and Y. Giving Error *'No route to host'* Although from computer B, I can access HTTPServer of computer B. Please help. -- Vedsar Kushwaha M.Tech-Computational Science Indian Institute of Science
