OpenStack Compute (nova)

I can`t get images from glance server

Asked by Hyuntae-Park

Hi all~

I have four physical servers and there is nova modules.

First node: nova-api,nova-objectstore,nova-scheduler,glance IP:10.250.0.1
Second node: nova-network IP:10.250.0.2
Third node: nova-compute IP:10.250.0.3
Fourth node: nova-volume IP:10.250.0.4

The problem is when I start run up a new instance, the Third node can`t get images from First node.

In Third node /var/lib/nova/instances/_base, there is only 0 byte file that name is 00000001.

If you are using trunk rev 1169 or newer, you need to change your two glance flags. They were consolidated into a single flag of <host[:port]> strings

--glance_host=10.250.0.1
--glance_port=9292

Would become:

--glance_api_servers=10.250.0.1:9292

Hi, Brian
Thanks for you answer.

I changed the two flugs as you said.

before
====================
--glance_host=10.250.0.1
--glance_port=9292
====================

after
====================
--glance_api_servers=10.250.0.1:9292
====================

and then I start run up a new instance, but I facing error too.

The result of the start instance operation in First node.

So it's pretty obvious from the log that the glance client is having trouble connecting to your glance server. Did you restart nova-api after making those configuration changes? Make sure you can access that ip/port from the API server, as well.

Thanks Brian Waldon, that solved my question.

You solved my problem.
But I don`t know why I failed first time.
I start up instance now, just 8 hours after.

Thank you Brian.

I have met the same question too. I have upgrade my openstack recently and it failed for the same reason. But I do the same before upgrade while it works.

my configuration file is :

--dhcpbridge_flagfile=/etc/nova/nova.conf
--dhcpbridge=/usr/bin/nova-dhcpbridge
--logdir=/var/log/nova
--state_path=/var/lib/nova
--lock_path=/var/lock/nova
--verbose

--s3_host=10.0.0.44
--rabbit_host=10.0.0.44
--cc_host=10.0.0.44
--ec2_url=http://10.0.0.44:8773/service/Cloud
--fixed_range=192.168.0.0/16
--network_size=60000
--FAKE_subdomain=ec2
--routing_source_ip=10.0.0.44
--sql_connection=mysql://root:sqlpasswd@10.0.0.44/nova
--glance_api_servers=10.0.0.44:9292
--daemonize=1

and the error message is the same as above.

Can you double-check that you restarted nova-api with that config file and that the ip/port are reachable?

Revision history for this message
xelatex (yzt356) said : 		#9

I have restarted all the service of nova- and the ip/port are reachable.
I can run the command "euca-describe-instance", but all the commands related to images fail.
I wonder if glance server is a must for openstack? In the old version glance server is not necessary to run nova.
Just with the same configuration, nova can run correctly before nova's last update, how could this happen?

The LocalImageService has been removed from Nova in favor of GlanceImageService with a local backend. Glance is a dependency and must actually be running at the ip/port defined in your config.

So, does that means I should explicitly install and configure glance server?

Revision history for this message
Brian Waldon (bcwaldon) said : 		#12

Yes. It is a pretty painless process. There's some helpful documentation here: http://glance.openstack.org/installing.html

Yeah, I installed glance and start the glance server with command "glance-control api start", then I can see the port 9292 is used.

Thanks.
