Hmm, I think there is a step missing in that tutorial (actually running the nova services and which nova.conf to use).

Let me ask around.

shihangwei,

I'm not really familiar with that tutorial, but here's what I would check:

1. make sure you source novarc
. novarc

2. you may need to restart the nova services. Do a 'ps' to find them and then /etc/init.d (assuming they're running as part of the package install) ... or are you running them all manually?

3. Regardless, make sure the services are running with a --flagfile=nova.conf statement in there. Could you post a copy of your nova.conf file please?

Let's see where that gets us. :)

hello, shihangwei is my colleague ,we are doing the same project.

as you said,

1, we really do ". novarc " to source novarc;

2,we restart nova services manually , when do "ps -A", the part of result as follows:

It the same as nova-scheduler --flagfile /etc/nova/nova.conf;

and the last post a copy of my nova.conf file:

hoping for your help, thank you very much!

I would suggest running nova with the flag files option. The output looks fine. I don't see any errors coming from it. Running without the .conf will certainly cause problems. Could you paste a 'ps -aux | grep nova' just so we I can ensure the correct nova.conf is being picked up?

From your process list above, compute and object-store aren't running, so that will definitely cause problems.

OK, here is the list of "ps -aux | grep nova":

[root@localhost dowmload]# ps -aux | grep nova

and I think that it's necessary to copy the result using nova-objectstore --flagfile /etc/nova/nova.conf and nova-compute --flagfile /etc/nova/nova.conf.

there seems some errors happen when opening nova-compute service.

and when we run or describe instances , some other errors occur like this:

Warning: failed to parse error message from AWS: <unknown>:1:0: syntax error

Add this to your nova.conf

--connection_type=libvirt

and cross your fingers :)

I am sorry to tell you, after add --connection_type=libvirt to nova.conf,

when nova-compute --flagfile /etc/nova/nova.conf , it's the same errors:

Generally this is from a missing python package (python-cheetah for example) if you add the following line:

raise

to line 56 of nova/utils.py (above the other exception) it will tell you which module it is failing to import.
