nova.conf query

Hi All,

A quick question regarding nova.conf: How can I modify nova.conf and get it to work with devstack. The problem that I am facing is after modifying nova.conf, I have to reboot so as to restart services. But when I reboot, devstack needs to be reinstalled all over again using stack.sh and in the process it rewrites /etc/nova/nova.conf.

Also according to documentation we can set flags in nova.conf using --<flag_name>=<flag_value> format. Is that an obsolete format ? (because the nova.conf that devstack creates don't have any -- in it).

Please let me know how to effectively modify nova.conf so that the changes take effect (I am looking forward to change the network manager...)

Thanks!

Salman

Re: nova.conf query [In reply to]

devstack runs all nova services in a screen backgroud.you can sudo
stack,then screen -S stack,you can see all services here.what you
need do is change the nova.conf then stop the releative services,then
start it again.

You can restart services without reboot like this

sudo service nova-compute restart

Essex has new format for nova.conf without dashes.

Re: nova.conf query [In reply to]

Yaguang,

I think you shoud type screen -x stack

If -S, I believe a new stack screen session would start.

Also I remember that devstack runs its services on the account you ran
stack.sh by default in the recent versions.

Re: nova.conf query [In reply to]

Here is one example, that I actually intended to configure:

http://docs.openstack.org/incubation/openstack-network/admin/content/EnablingQuantumManager-d1e453.html

But there are plenty out there I guess...

devstack supports an EXTRA_OPTS flag in it's localrc that will let you
set additional values in there. You can set more than one flag by using
bash arrays, i.e.:

EXTRA_OPTS=(logdir=/var/log/nova auto_assign_floating_ip=True)

If you are using devstack, it's quite worth reading through the script
as well. It's pretty well documented, and there are lots of gems in
there like that.
