Can you check compute service is up ? Can you try telnet 192.168.1.12 8774. Does this work ?

Compute should be up right ? If not up, it will surely give the above problem. Please restart all your services and try again.

I got same error. I see that in all openstack based service include /etc/"service"/"service.conf". in which one line "connection = ..." In section [database]. if you forgot to update it to correct. you will get same error. so always first check it.

actually I discovered that the problem was due to the size of the RAM of the VM. In fact, when I increased it everything worked ordinarly. Thank you.

I used to use 1GB. But after getting into trouble with MySQL and this. I safely give my VM 1.5GB of memory.

Ensure that your nova-api service is running on host having IP 192.168.1.12 and is listening on port 8774.

if it is not the case, what should I do?

You need to check for the nova-api service logs (devstack defaults to /var/log/nova/api.log) to determine the cause of service start up failure. Paste the logs onto paste.openstack.org and provide the link here if you need help in tracking down the issue.

Hi! I have the same problem as yours. I use my laptop as host platform to install OpenStack via devstack and meet the same problem as yours. Did you mean if you increase the size of your host machine memory, then the problem will be solved? Thanks!

Ok, in my case, while I am trying this on Ubuntu 14.04 and Juno on the below command I would get the status as below and the logs were frozen.

service nova-api start

nova-api stop/waiting

For some strange reason nova-api had gone missing, reinstalling it fixed the problem.

It most likely due to having to little memory, check requirements on devstack dot org

I guess it all boils down to the OOM implementation of Linux. It's Linux handling out-of-memory situations. nova-api process is being killed. See console or grep messages for "killed process"

The behaviour can be altered. Read up by googling "OOM killer"
