Nova service fails after rebooting

Question

Devstack installed on Virtualbox VM with Ubuntu 20.04

Succesfully created Cirros tiny VM. But after rebooting this 3 services are failed with similar errors: devstack@n-cond-cell1.service, devstack@n-sch.service, devstack@n-super-cond.service

stack@controller:~$ systemctl status devstack@n-cond-cell1.service --no-pager -l

How to fix it?

Answer 1

According to this error tip: Unable to establish connection to http://65.152.254.100/identity , make sure that you had source the right rc file such as admin-openrc.sh and check the environment parameter auth_url . Then check the.network connection whether success to (host='65.152.254.100', port=80) , maybe there is some firewall limit like iptables .

Mostly someone miss the IDENTITY_API_VERSION in the auth_url .

In my openstack development environment which deploy by kolla-ansible although, I guess it's similar with your issue. And you should check whether the endpoints value works or not.

# source /etc/kolla/admin-openrc.sh
# echo $OS_AUTH_URL 
http://10.10.10.100:35357/v3

# openstack endpoint list

| 1*b | RegionOne | keystone     | identity       | True    | admin     | http://10.10.10.100:35357   |

Answer 2

I using default source file. And there is no any firewall or iptables.

stack@controller:~$ source devstack/openrc admin admin
