Common Errors:

Install DevStack, stack.sh fails “Keystone did not start!”

This error is usally happends after stack.sh has been going, the reason keystone can’t start up is likely because the HOST_IP parameter in local.conf is not correct, double check the address and make sure it matches the eth0 interface (ip addr show dev eth0)

Solution: fix the config typo and run ./unstack.sh and re-run ./stack.sh
