Hi have you tested launching instances using cirros ? Are using Neutron with Linuxbridge or OpenVSwitch. How you have installed openstack it is manual installation of services or testing with Packstack?

Please check nova compute log, nova scheduler log, neutron server log, cinder volume log and cinder scheduler log for any ERROR . This may give you some clue about your issue..!!

BTW Is this multi node OpenStack setup ? seems like volume creation failed.. Are all the OpenStack services are up (active and enabled) ? You may try to launch instance being New Volume Creation set to No in GUI..!!
