differences between epel and official RHEL-OpenStack
by Florian La Roche 29 Nov '12

29 Nov '12

Hello, Seems like Red Hat is building the official Red Hat OpenStack product rpms sometimes with the exact same name as the ones within EPEL. The below difference shows that in this case EPEL seems to be a bit ahead, but it also looks like this fix is then also not yet merged into the Folsdom release that should show up for RHEL6.4. There are other rpms where also changes are done to dependencies without any changelog entry. Often with changing the version name, but not always. All this is usually a bad idea. Best regards, Florian La Roche P.S.: A big thanks for providing a current OpenStack in EPEL, that's a huge win for all cloud testers out there. --- Look at changes from python-daemon-1.5.2-1.el6.src.rpm to python-daemon-1.5.2-1.el6.src.rpm old: total 12 drwxrwxr-x. 2 laroche laroche 4096 Nov 29 11:40 . drwxrwxr-x. 4 laroche laroche 4096 Nov 29 11:40 .. -rw-r--r--. 1 laroche laroche 1618 Nov 29 11:40 python-daemon.spec new: total 12 drwxrwxr-x. 2 laroche laroche 4096 Nov 29 11:40 . drwxrwxr-x. 4 laroche laroche 4096 Nov 29 11:40 .. -rw-r--r--. 1 laroche laroche 1671 Nov 29 11:40 python-daemon.spec diff -urN old/python-daemon.spec new/python-daemon.spec --- old/python-daemon.spec 2012-11-29 11:40:02.184712732 +0100 +++ new/python-daemon.spec 2012-11-29 11:40:02.196714905 +0100 @@ -13,7 +13,7 @@ BuildArch: noarch BuildRequires: python-devel, python-setuptools -BuildRequires: python-nose python-lockfile +BuildRequires: python-nose python-lockfile python-minimock Requires: python-lockfile %description @@ -35,6 +35,10 @@ %{__python} setup.py install -O1 --skip-build --root $RPM_BUILD_ROOT +%check +PYTHONPATH=$(pwd) nosetests + + %clean rm -rf $RPM_BUILD_ROOT

no sig irc meeting today (but, aws conference!)
by Matthew Miller 28 Nov '12

28 Nov '12

I'm at AWS re:Invent. No SIG meeting -- sorry, I should have sent this out earlier. But, if you are at this conference, I'd love to meet you in person at some point. :) -- Matthew Miller ☁☁☁ Fedora Cloud Architect ☁☁☁ <mattdm(a)fedoraproject.org>

cloud-init package dependencies
by Matthew Miller 27 Nov '12

27 Nov '12

cloud-init pulls in some, um, not exactly minimal stuff. python-cheetah? (which then brings in, for example, freetype...) Can we narrow this down without significantly killing functionality? -- Matthew Miller ☁☁☁ Fedora Cloud Architect ☁☁☁ <mattdm(a)fedoraproject.org>

cloud-init update
by Garrett Holmstrom 27 Nov '12

27 Nov '12

Hi, everyone, I just pushed the final (i.e. non-snapshot) version of cloud-init 0.7.0 to F18 and rawhide, which fixes a great deal of compatibility bugs, makes most of the plugins work properly, and allows one to configure the users on the system using instance user-data a lot better than previous version. There is one fairly important change to be aware of relative to F17's version: this version allows you to change the user that it creates at startup time (and in fact add even more), so it is recommended to *not* pre-create a user when you build the image. What do we need to do to remove that from Fedora's cloud image kickstart before we start building test images? I'd like to push this to F16 and F17 as well to replace the horribly broken versions that those operating systems shipped with. Any objections? How about EPEL? This update fixes so many issues that I believe it's worth it. -- Garrett Holmstrom

Adding a compute node and quantum configurations
by nux＠li.nux.ro 20 Nov '12

20 Nov '12

Hello, The quantum network side is not covered in https://fedoraproject.org/wiki/Getting_started_with_OpenStack_EPEL#Adding_a… so I'm trying to clarify this. On a second node I've followed the instructions in the wiki minus the network obviously since I'm running quantum+openvswitch (hybrid). I'm applying some of the instructions found here: https://fedoraproject.org/wiki/QA:Testcase_Quantum_V2#Setup but when I'm doing "quantum-server-setup --plugin openvswitch" it's asking me to install mysql, the scripts should be modified to also ask if there's a DB running elsewhere (i.e. on the controller). Anyway, I let it do its thing, install mysql and setup nova.conf, then modified nova.conf with the quantum section from the controller's nova.conf. Now my question is - in this case quantum_admin_auth_url and quantum_url on the node should they point to localhost or to the controller's address? I'm thinking quantum_admin_auth_url should point to the keystone service on the controller's IP and quantum_url should be http://localhost:9696/? Additionally: quantum.conf - qpid_hostname should point to the controller's IP quantum/api-paste.ini - [filter:authtoken] auth_host should be the controller quantum/l3_agent.ini - auth_url should point to the controller plugins/openvswitch/ovs_quantum_plugin.ini - sql_connection should be using the controller's mysql server Let me know if any of that is wrong or I missed some other settings that should be notified.

NIC type (rtl vs virtio)
by nux＠li.nux.ro 19 Nov '12

19 Nov '12

Hi, I notice the VMs are not using the virtio type NICs, but some "Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+". In my experience the virtio device is quite stable, any reason why it's not default? I see that for block device virtio is default. -- Sent from the Delta quadrant using Borg technology!

Cinder issues with Openstack EPEL
by nux＠li.nux.ro 19 Nov '12

19 Nov '12

Hello chaps, I'm having some problems with Openstack Cinder (who doesn't :> ) Some info: OS: CentOS 6.3 + EPEL + EPEL-testing, default firewall on, selinux on I followed these instructions http://fedoraproject.org/wiki/Getting_started_with_OpenStack_EPEL skipping "Setup volume storage" because I have a physical LVM partition called "cinder-volumes" and also skipping "Nova Network Setup" because I want Quantum. As I said I do have a VG called cinder-volumes and have modified tgtd to include include /etc/cinder/volumes/* When I try to create a volume I see this in cinder/api.log: 012-11-17 19:11:50 AUDIT cinder.api.openstack.volume.volumes [req-22f1bfdc-67fd-4464-9a4b-1701e3547838 bb48f2ad7a45420ea80f8bdda97e0d54 cc3005e2733e423bbe1bf24931447294] Create volume of 1 GB 2012-11-17 19:11:50 AUDIT cinder.api.openstack.volume.volumes [req-22f1bfdc-67fd-4464-9a4b-1701e3547838 bb48f2ad7a45420ea80f8bdda97e0d54 cc3005e2733e423bbe1bf24931447294] vol={'availability_zone': 'nova', 'terminated_at': None, 'updated_at': None, 'provider_auth': None, 'snapshot_id': None, 'ec2_id': None, 'mountpoint': None, 'deleted_at': None, 'id': '0a29a3db-0b25-41bb-81c3-4e3d277e5a4a', 'size': 1, 'user_id': u'bb48f2ad7a45420ea80f8bdda97e0d54', 'attach_time': None, 'display_description': u'', 'project_id': u'cc3005e2733e423bbe1bf24931447294', 'launched_at': None, 'scheduled_at': None, 'status': 'creating', 'volume_type_id': None, 'deleted': False, 'provider_location': None, 'host': None, 'display_name': u'1', 'instance_uuid': None, 'created_at': datetime.datetime(2012, 11, 17, 19, 11, 50, 226521), 'attach_status': 'detached'} 2012-11-17 19:11:50 INFO cinder.api.openstack.wsgi [req-22f1bfdc-67fd-4464-9a4b-1701e3547838 bb48f2ad7a45420ea80f8bdda97e0d54 cc3005e2733e423bbe1bf24931447294] http://127.0.0.1:8776/v1/cc3005e2733e423bbe1bf24931447294/volumes returned with HTTP 200 2012-11-17 19:11:50 INFO cinder.api.openstack.wsgi [req-071e26ef-f710-4548-bf7a-da0518113dd6 bb48f2ad7a45420ea80f8bdda97e0d54 cc3005e2733e423bbe1bf24931447294] GET http://127.0.0.1:8776/v1/cc3005e2733e423bbe1bf24931447294/volumes/detail 2012-11-17 19:11:50 AUDIT cinder.api.openstack.volume.volumes [req-071e26ef-f710-4548-bf7a-da0518113dd6 bb48f2ad7a45420ea80f8bdda97e0d54 cc3005e2733e423bbe1bf24931447294] vol=<cinder.db.sqlalchemy.models.Volume object at 0x427bad0> 2012-11-17 19:11:50 INFO cinder.api.openstack.wsgi [req-071e26ef-f710-4548-bf7a-da0518113dd6 bb48f2ad7a45420ea80f8bdda97e0d54 cc3005e2733e423bbe1bf24931447294] http://127.0.0.1:8776/v1/cc3005e2733e423bbe1bf24931447294/volumes/detail returned with HTTP 200 This in cinder/scheduler.log: 012-11-17 19:14:48 3689 ERROR cinder.openstack.common.rpc.amqp [-] Exception during message handling 2012-11-17 19:14:48 3689 TRACE cinder.openstack.common.rpc.amqp Traceback (most recent call last): 2012-11-17 19:14:48 3689 TRACE cinder.openstack.common.rpc.amqp File "/usr/lib/python2.6/site-packages/cinder/openstack/common/rpc/amqp.py", line 276, in _process_data 2012-11-17 19:14:48 3689 TRACE cinder.openstack.common.rpc.amqp rval = self.proxy.dispatch(ctxt, version, method, **args) 2012-11-17 19:14:48 3689 TRACE cinder.openstack.common.rpc.amqp File "/usr/lib/python2.6/site-packages/cinder/openstack/common/rpc/dispatcher.py", line 145, in dispatch 2012-11-17 19:14:48 3689 TRACE cinder.openstack.common.rpc.amqp return getattr(proxyobj, method)(ctxt, **kwargs) 2012-11-17 19:14:48 3689 TRACE cinder.openstack.common.rpc.amqp File "/usr/lib/python2.6/site-packages/cinder/scheduler/manager.py", line 98, in _schedule 2012-11-17 19:14:48 3689 TRACE cinder.openstack.common.rpc.amqp db.volume_update(context, volume_id, {'status': 'error'}) 2012-11-17 19:14:48 3689 TRACE cinder.openstack.common.rpc.amqp File "/usr/lib64/python2.6/contextlib.py", line 23, in __exit__ 2012-11-17 19:14:48 3689 TRACE cinder.openstack.common.rpc.amqp self.gen.next() 2012-11-17 19:14:48 3689 TRACE cinder.openstack.common.rpc.amqp File "/usr/lib/python2.6/site-packages/cinder/scheduler/manager.py", line 94, in _schedule 2012-11-17 19:14:48 3689 TRACE cinder.openstack.common.rpc.amqp return driver_method(*args, **kwargs) 2012-11-17 19:14:48 3689 TRACE cinder.openstack.common.rpc.amqp File "/usr/lib/python2.6/site-packages/cinder/scheduler/simple.py", line 78, in schedule_create_volume 2012-11-17 19:14:48 3689 TRACE cinder.openstack.common.rpc.amqp raise exception.NoValidHost(reason=msg) 2012-11-17 19:14:48 3689 TRACE cinder.openstack.common.rpc.amqp NoValidHost: No valid host was found.
