Hi, I am running devstack on Ubuntu, when i am trying to run anything which is related to Nova such as :

nova list, nova service-list etc.

I am getting 

ERROR (ConnectFailure): Unable to  establish connection to  http://MY.IP.ADDRESS:8774/v2.1/533aa7ac0e544e83956fa55e2a0fa542

Can someone please assist with that?

---edit ----

matan@matan-virtual-machine:~$ sudo netstat -ntlp | grep 8774 returns nothing

The output of keystone endpoint-list is:

Hi, your compute service (nova) is not running. Please restart it and try again. It will work.

I can't understand how to restart nova specifically on devstack

Hello

1. cd to devstack home
2. run ./rejoin-stack
3. find the nova-api service by press crl+a +" then select the nova-api eg: n-api then press enter key
4. kill the nova-service by crl+ c then press up arrow key to find the command to start the nova api and press enter, you will see the nova-api service restarted.

Regards

best way to check if the services are running or not . Please install openstack-utils package in the server.

It will install the command openstack-status which will tell you what all the services are running or not.

In this case, nova-api might not be running. Did you check the logs in /var/log/nova ?

It is devstack, it doesn't have a /var/log/nova file..
