Hi, I installed openstack using Devstack environment. But now i am not able to launch an instance. When i do so no availability zones are available plus it gives an error without any description when i launch it. I am not able to view any openstack services logs (nova, neutron etc.). In stack.sh.logs also i am not able to view anything. Is there any error?? I am not able to understand anything. Please help me what i am doing wrong.. I checked in var/log/syslog but i found nothing. Also tell me about local.conf, currently i am using localrc. Will it be sufficient? or should i use some local.conf by putting stackrc and localrc files together in it??? Please help.

Can you unstack, check all virutualization components are installed (libvirt server, kvm, qemu) as in this bug https://bugs.launchpad.net/nova/+bug/... and then stack again.

You need to have availability zones to launch VMs.

A quick check, see whether nova compute (n-cpu) is running by clicking on "system info" of Admin panel. If you are using ubutu, follow this bug link.

Thanks.

I am not able to find log files of nova. I checked in /var/log and there are no nova, neutron folders. Where are the logs available if i install during devstack? In "system info" of Admin Panel, i can see all services are enabled(nova-compute, nova-computev3, neutron-network and others). All network agents are also up and running. Please note that i did not have any errors during installation of devstack. It is only the instance creation which is encountering the problem.

If n-cpu is running, are you sure that there are no availability zones are available?

If you are using devstack, you can use the localrc for the present though the local.conf is recommended. As for the log stuff, if you did not specify the SCREEN_LOG env variable in localrc all logs will remain in screen session, you can check them by login into the screen

cd devstack
./rejoin-stack.sh

Please check every service in the screen make sure they are running without any error then provision instance again and check the nova-scheduler screen window to see if any error occured.

Hope that helps.
