You can get a better idea of what's going on by looking at the other nova log files as Vikash suggested. I would start with the nova-scheduler log if your nova-api log looks clean. This slideshow is a bit dated, but has a decent overview of how nova works when provisioning a VM. While it is old and doesn't include a placement API, it's still a useful reference for troubleshooting VM provisioning: https://www.slideshare.net/anandnande/openstack-nova-deep-dive I hope that helps :) On Sun, Mar 19, 2017 at 6:35 PM, jt628910 at 163.com <jt628910 at 163.com> wrote: > thanks，this has resolved。 > > But the vm is still schedulering，and have no error log，what happen？ > > > ------------------------------ > jt628910 at 163.com > > *From:* Jay Pipes <jaypipes at gmail.com> > *Date:* 2017-03-16 22:25 > *To:* openstack <openstack at lists.openstack.org> > *Subject:* Re: [Openstack] Placement service credentials do not work > The error is: > > On 03/16/2017 07:01 AM, Vikash Kumar wrote: > > Placement service credentials do not work > > Check that the user "placement" in the project "service" having the > password "testetst" can access the Keystone authentication endpoint at > "http://10.1.110.98:5000". > > Best, > -jay > > _______________________________________________ > Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/ > openstack > Post to : openstack at lists.openstack.org > Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/ > openstack > > _______________________________________________ > Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/ > openstack > Post to : openstack at lists.openstack.org > Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/ > openstack > > -------------- next part -------------- An HTML attachment was scrubbed...
