Hi guys, I'm trying to troubleshoot why I can't launch an instance and I noticed that I only have this nova services listed:

nova-manage service list

Binary           Host                                 Zone             Status     State Updated_At
nova-consoleauth openstack-controller                 nova             enabled    :-)   2013-04-23 15:59:53
nova-cert        openstack-controller                 nova             enabled    :-)   2013-04-23 15:59:53
nova-scheduler   openstack-controller                 nova             enabled    :-)   2013-04-23 15:59:53

Is that right?

Thx.

Hey, where is your nova-compute service is running ? It should display in nova-manage service list o/p.

I don't see nova-compute listed but when I do # service nova-compute status # I get: # nova-compute stop/waiting #

Hello,

As of Grizzly, you should see the following services:

Binary           Host                Zone             Status     State Updated_At
nova-cert        cloud               nova             enabled    :-)   2013-04-23 16:50:43
nova-consoleauth cloud               nova             enabled    :-)   2013-04-23 16:50:43
nova-scheduler   cloud               nova             enabled    :-)   2013-04-23 16:50:43
nova-conductor   cloud               nova             enabled    :-)   2013-04-23 16:50:43
nova-compute     c01                 nova             enabled    :-)   2013-04-23 16:50:44

Depending on your OpenStack installation, nova-compute may be running on a separate server or the same server as the other services.

Hi, thanks for your answer, I am installing with Folsom release, I should have the same services too?

I have only this on Controller node: *-consoleauth, *-scheduler and *-cert On compute node: *-consoleauth, *-scheduler and *-cert

What am I doing wrong ? :s

Only nova-compute needs to be running on your compute node. If you're using Folsom, you won't have the nova-conductor service as it is new to Grizzly, but all of the other services are the same.

Thank you! .. now I'm trying to put nova-compute into the service list... when I try virsh list I get "Failed to connect to the hypervisr, No such file or directory"... I have reisntalled libvirt and configured everything again and nothing...

Hi jtopjian.. I decided to install Grizzly, I have installed everything according to the guide for grizzly in openstack documentation but when I run nova-manage service list I can't see nova-conductor not even nova-compute.. I verified and both services are in running status.. What can be wrong? Thx

Hi,

Openstack have a distributed architecture each of its components can run on separate machines like Quantum , Cinder , Nova ,Glance etc

If you have a single node setup then all the service should be running on a same machine and it should display the o/p of

nova-manage service list

  • nova-compute controller nova enabled :-)
  • nova-scheduler controller nova enabled :-)
  • nova-conductor controller nova enabled :-)
  • nova-cert controller nova enabled :-)
  • nova-consoleauth controller nova enabled :-)

If you have multinode setup then nova-compute is running on computeNode and

nova-manage service list should display:

  • nova-compute computeNode nova enabled :-)
  • nova-scheduler controller nova enabled :-)
  • nova-conductor controller nova enabled :-)
  • nova-cert controller nova enabled :-)
  • nova-consoleauth controller nova enabled :-)

TO make it work do the proper configuration and run the NTP server to sync both machine and check the rabbitMQ works properly.

Hi, thanks. I have multinode... how can I check if rabbitMQ works properly? And how can I sync the NTP ? I have configured all according to the guide for folsom in the openstack documentation... Sorry I'm a little "noob" ..

henrik16 gravatar imagehenrik16 ( 2013-04-24 08:11:32 -0500 )edit

nova-compute was not showing up because the machine where this service was installed did not support hypervisor

Hi again @RomilGupta, do I need "nova-network" running? I saw this in many people's configuration and my problem is about network.. I can't connect to my VM with an IP of 192.168.2.3 ... my physical machines have 192.168.0.1 - .3 and 192.168.1.2 - .3 what do I need to do to get this to work?

henrik16 gravatar imagehenrik16 ( 2013-05-02 06:14:49 -0500 )edit

I have done this according to the guide.. so, what am I doing wrong? Thanks.

henrik16 gravatar imagehenrik16 ( 2013-05-02 06:15:00 -0500 )edit

Hi henrik , if you are using nova-network then it should be running in your computeNode.
