(docker.x86_64    2:1.13.1-55.rhel75.git774336d.el7).

From the nova-conductor.log we see that the instance fails to get an IP address from the DHCP server, also from the ironic-conductor snippet(2), we see that the name server here is 192.168.24.1 which is invalid and deployment steps timeout trying to get an IP from the incorrect name resolution.
Comment 1 Bob Fournier 2018-02-27 13:47:00 UTC 
Shashank - based on the logs this appears to be a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1549170.

You'll need to pick up the latest puddle which has a fix.
