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.

nova-compute

You can see how each Nova service is run here: http://wiki.openstack.org/XenServerDevelopment?action=subscribe#Run_Nova (http://wiki.openstack.org/XenServerDe...)

Hope it helps!

Looks like Glance is not installed: No module named glance.client

Vish ... didn't know about that 'raise' trick. Good to know.

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

[root@localhost dowmload]# ps -aux | grep nova Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.7/FAQ root 6628 0.3 0.7 211512 27588 pts/2 S+ 09:23 0:03 /usr/bin/python /usr/bin/nova-network --flagfile /etc/nova/nova.conf root 6682 0.0 0.6 207192 23564 ?

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.

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. :)
