| _nil | kpepple: i'm still not sure the best place for me to help | 01:57 |

| _nil | just direction | 01:57 |
| _nil | :) | 01:57 |
| winston-d | kpepple : hi | 01:58 |
| winston-d | kpepple : what would happen if certain instance_type was removed from database but there's an instance w/ that type still running? | 02:01 |
| *** rchavik has quit IRC | 02:04 | |
| kpepple | winston-d: hi | 02:04 |
| kpepple | winston-d: that shouldn't be a problem ... we originally didn't have a foreign key in the instances table back to instance_types but we added one just before cactus release ... still i think that we just get an empty list if we query for the instance_type that was removed. also, it's hard to actually remove an instance_type from the table, you have to use the --purge option not just delete | 02:06 |
| kpepple | _nil: hi | 02:06 |
| winston-d | kpepple : yeah, i know. i tested create/delete instance_types and found i could not add new one with that flavor id which was deleted. then i go check your blog and find out --purge must be used to actually remove it from DB. | 02:08 |
| kpepple | _nil: areas that can use help: document (see http://wiki.openstack.org/Documentation/HowTo), testing (learn python mox), answers (help at https://answers.launchpad.net/nova) and lastly coding (yes, you need to know Python but it's pretty easy to learn if you have some object oriented experience) | 02:09 |
| kpepple | winston-d: in the new version of nova (trunk), you actually get a nice new error message which shows you which instance_types are duplicates :) | 02:09 |
| _nil | kpepple: i know python | 02:11 |
| *** jakedahn has quit IRC | 02:11 | |
| _nil | but it doesn't seem like you need coders as you list it last. | 02:11 |

| _nil | well those are my favorites | 02:11 |
| kpepple | _nil: oh no, we need coders | 02:11 |
| _nil | ok | 02:11 |
| _nil | well i'm game to help when i can | 02:11 |
| _nil | i want to start using this on duckduckgo | 02:12 |
| _nil | s/on/for/g | 02:12 |
| kpepple | _nil: i jumped in with starting bug fixes ... it's a way to learn your way around codebase in small chunks | 02:12 |
| _nil | i just need to know where the hot spots are | 02:12 |
| KnightHacker | _nil: Are you planning on using Nova for duckduckgo? | 02:12 |
| _nil | considering it | 02:12 |
| _nil | more fun to work on open source stuff first and then see if it's useful | 02:13 |
| _nil | this project caught my eye and i need a break from the go compiler tbh | 02:13 |
| KnightHacker | wow .. that sounds cool :). I was just checking out the architecture used for duckduckgo | 02:13 |
| _nil | cool | 02:13 |
| _nil | growth has been pretty crazy over there for some time. | 02:14 |
| KnightHacker | Yeah, that's why I was interested to see how are you handling the scale with your infrastructure. | 02:14 |
| _nil | ;) | 02:15 |
| KnightHacker | I was surprised but glad to see you using *BSD systems there. | 02:15 |
| _nil | both the founder and myself are pretty big FreeBSD nerds | 02:15 |
| kpepple | _nil: i tend to work on the nova operational side (things like nova-manage, instance_types, etc that ops people like to use), but there is a ton of oppty everywhere. volume support is being worked on (nova-volume), there is a new load balancer project, networking is being expanded and reworked, authn/authz is becoming a new services ... i'd just look for something that interests you and dive in | 02:15 |
| _nil | though i've been using ubuntu a lot recently | 02:15 |
| _nil | ok | 02:16 |

| winston-d | kpepple : does nova trunk now expose the '--purge' parameter for instance_type delete command, IMHO, it should be. | 02:18 |
| _nil | kpepple: neat. thanks guys. | 02:18 |
| kpepple | _nil: np | 02:19 |
| kpepple | winston-d: what do you mean by 'expose' ? yes, it accept it | 02:20 |
| winston-d | kpepple : i thought '--purge' was already in Cactus release but 'nova-mange instance delete' only suggest one argument, that's name of instance_type. | 02:21 |
| kpepple | winston-d: oh, no it doesn't actually suggest that to you ... you have to read the man page to learn that sekrit :) | 02:24 |
| kpepple | winston-d: and yes, it should be how nova-manage is written, it doesn't do it automagically | 02:24 |
| winston-d | kpepple : so '--purge' was hidden secret agrument in Cactus :) | 02:25 |
| winston-d | kpepple : hmm, no man entry for 'nova-mange' | 02:25 |
| *** hadrian has quit IRC | 02:26 | |

| soren | toluene: Yeah, I know what the problem is. | 07:00 |
| soren | toluene: You're connecting from localhost, but the password is set for root@%. | 07:01 |
| soren | toluene: Why the instructions suggest that you use the mysql root user for nova is absolutely beyond me. | 07:01 |
| toluene | soren, what should I do ? | 07:01 |
| soren | toluene: Something like this: | 07:03 |
| soren | toluene: Fire up the mysql client, logging in as root. | 07:03 |
| soren | toluene: Then do this | 07:04 |
| soren | toluene: grant all on nova.* to 'nova'@'%' identified by 'somepassword'; | 07:04 |
| soren | toluene: ...and in your nova.conf, you change the sql_connection to: | 07:04 |
| soren | toluene: --sql_connection=mysql://nova:somepassword@127.0.0.1/nova | 07:05 |
| soren | That should do the trick. If not, I have one more thing that may need to be done, but I'm not sure it's necessary, so let's try this first. | 07:06 |

| pgregory | morning | 07:38 |
| pgregory | could someone tell me if it's possible/reasonable to allow multiple users to create instances for a project? | 07:38 |
| *** nacx has joined #openstack | 07:40 | |
| HugoKuo__ | pqregory : yes | 07:40 |
| HugoKuo__ | 1.add the user to project 2.allocate sysadmin role for both global and project environment | 07:41 |
| pgregory | HugoKuo__: would that give the user systemwide access? | 07:42 |
| HugoKuo__ | As I know , only sysadmin / projectmanager role has permission to lunch instance | 07:43 |
| HugoKuo__ | about your question : no | 07:44 |
| HugoKuo__ | user management depends on RBAC | 07:44 |
| pgregory | that seems to have worked. | 07:45 |
| pgregory | thanks | 07:45 |
| HugoKuo__ | sure .... | 07:45 |
| HugoKuo__ | see ya | 07:45 |
| pgregory | is that 'normal' or is it preferred that only one user can create instances for a project? | 07:45 |
| * pgregory is a bit confused about the role of the 'project' in the cloud scheme. | 07:46 | |
| HugoKuo__ | sysadmin is a little different from project manager | 07:47 |
| pgregory | I'm just wondering if it's better to have 1 project that multiple users can interact with, or give each user a project(s)? | 07:48 |
| HugoKuo__ | in my environment , per project / per user... | 07:48 |
| HugoKuo__ | I recommand each user a project | 07:49 |
| pgregory | I see | 07:49 |
| HugoKuo__ | btw a user can add to multi project | 07:49 |
| pgregory | so a project is an organisational level 'below' user. | 07:49 |
| pgregory | I was thinking of the project as being at a higher level. | 07:50 |
| HugoKuo__ | the reason is...... all project sysadmins are free to run or "terminate" instance | 07:50 |
| HugoKuo__ | it's quite danger | 07:50 |
| pgregory | for example, in my usage case we would have 'productions' and that would relate to a 'project' but it makes more sense I think to just have users, and create a default project for each user, and then create other projects for users who need more fine grained control. | 07:51 |
| HugoKuo__ | Actually , I made mistake before :\ , terminate my leader's intance | 07:51 |
| HugoKuo__ | yes , you r right...I agree with you | 07:51 |
| pgregory | thanks, that clears things up a bit. | 07:52 |
| HugoKuo__ | RBAC cost me lots of time ....before :) | 07:52 |

| pgregory | is there any way of assigning a more meaningful description to a published image (Dashboard) or is it always going to show the manifest name? | 08:10 |
| soren | pgregory: If you use glance, yes. | 08:12 |
| pgregory | oh, is that going to be a pain, or is it easy to switch? | 08:12 |
| soren | pgregory: I've not really used glance much myself, I'm afraid. | 08:13 |

| pgregory | will it work with the Dashboard? | 08:13 |

| pgregory | soren: can I trust in the manual for this? | 08:14 |
| soren | For what, exactly? | 08:14 |
| soren | Hmm... | 08:15 |
| pgregory | setting up glance | 08:15 |
| soren | Whatever your response, I probably don't know the answer. I've not personally proofread the manual. | 08:15 |
| HugoKuo__ | pgregory : it's easy | 08:16 |
| pgregory | HugoKuo__: should I just follow the manual, or is there a better reference. | 08:16 |
| HugoKuo__ | just add three flags.... | 08:16 |
| HugoKuo__ | yes | 08:16 |
| HugoKuo__ | follow it | 08:16 |
| * pgregory feel confident enough now that he can rebuild this if it all goes pear shaped. | 08:16 | |

| pgregory | HugoKuo__: is it possible to get glance to use my existing objectstore, or do I need to re-publish my images? | 08:37 |
| HugoKuo__ | pgregory : you need to convert the image from objectstore | 08:37 |
| toluene | soren, here is the paste http://pastebin.com/hsaZfetp | 08:38 |
| pgregory | HugoKuo__: so does glance not work with objectstore? does it have to use file based storage? | 08:38 |
| HugoKuo__ | let me clear it, objectstore is nova-objectstore ? | 08:39 |
| HugoKuo__ | or swift ? | 08:39 |
| pgregory | yes | 08:39 |
| pgregory | no, just nova-objectstore | 08:39 |
| pgregory | it's what I've been using up to now, and seems to be ok for my requirements. | 08:39 |
| HugoKuo__ | https://answers.launchpad.net/nova/+question/153430 take a look | 08:40 |
| HugoKuo__ | you will know , I'm poor in engilsh.............. :\ | 08:41 |
| pgregory | HugoKuo__: I'm not really following that, it seems to suggest that you need to use the file based store. | 08:44 |
| HugoKuo__ | but nova-objectstore is file based store too | 08:45 |
| HugoKuo__ | or you can choose swift for store image | 08:45 |
| pgregory | hmm, I'm confused then. | 08:45 |
| HugoKuo__ | just a name nova-objectstore | 08:46 |
| pgregory | do I leave the glance.conf with 'file' as the default_store? if so, how do I get my existing images (in mybucket on objectstore) into glance, so that they show up in dashboard? | 08:46 |
| HugoKuo__ | a path to store object , not means objectstorage ... | 08:47 |
| HugoKuo__ | yes | 08:47 |
| HugoKuo__ | sure ....the easiest way | 08:47 |
| HugoKuo__ | convert !!! | 08:47 |
| pgregory | so just get the .tar.gz again, and register with glance, or upload with uec-publish-tarball? (I'm a bit confused) | 08:48 |
| HugoKuo__ | nova-manage image convert /path/to/images | 08:48 |
| HugoKuo__ | no | 08:48 |
| HugoKuo__ | your existing image is in /var/lib/nova/images | 08:48 |
| HugoKuo__ | choose one for testing | 08:49 |
| pgregory | so I can just do "sudo nova-manage image convert /var/lib/nova/images"? | 08:50 |
| pgregory | 'sok, I sorted it, I just used uec-publish-tarball, and it seemed to work fine. | 09:07 |
| soren | toluene: Is nova-api running? | 09:09 |
| toluene | soren, I have no idea, my apt is messup , I 'm now reinstalling the ubuntu, what a bad day. I have recorded the tips you had gave me. | 09:12 |

| toluene | soren, Yes, I doing thing using source. I'm a gentoo guy | 09:14 |
| soren | Now you've lost me. Are you doing this on Gentoo or Ubuntu? | 09:14 |
| toluene | soren, My team use ubuntu so I use ubuntu, at home I use gentoo. | 09:15 |
| toluene | soren, I'm using ubuntu to install openstack | 09:16 |
| soren | So why install from source? | 09:16 |
| toluene | soren, I think using source is the best way to use up-to-date openstack | 09:18 |

| Bat_ | Really, really important. | 10:09 |
| btorch | what's the issue ? i can try | 10:11 |
| pgregory | anyone know how I get a description into a glance image metadata that will show up in Dashboard in place of the location? | 10:31 |
| pgregory | I've looked into the Dashboard code, and it checks for the existence of 'description' and uses it if it's there, or uses 'location' if not. | 10:31 |
| pgregory | so I jumped through hoops with the glance cli tool (why on earth does it wipe any properties not specified in the update command?) to get a description property in there, and it doesn't make any difference, still shows the location. | 10:32 |
| soren | pgregory: It wipes the stuff not set in the update command, because that's the only useful way you can offer a way to delete properties. | 10:35 |
| *** dirkx_ has joined #openstack | 10:35 | |
| pgregory | soren: perhaps a separate command then, 'update' doesn't imply delete to me, perhaps that's just me. | 10:36 |
| pgregory | anyway, I've now tried 'description', 'image_description' none of them show up, any ideas? | 10:36 |
| soren | pgregory: Think of it as "update my set of properties to this". | 10:37 |
| pgregory | soren: I see | 10:37 |
| pgregory | fair enough. | 10:37 |
| soren | pgregory: I could probably stare at the code and work it out, but I need food to fuel my brain. | 10:37 |
| pgregory | I've looked at the code, Django is a bit of a maze, but still can't work it out. | 10:38 |

| *** Bat_ has quit IRC | 10:46 | |
| *** Bat__ has joined #openstack | 10:47 | |
| Bat__ | Ok, sorry | 10:47 |
| Bat__ | So my problem is | 10:47 |
| Bat__ | I'm using switf + S3 middleware written in python in order to get interface compatible to S3 for my application | 10:47 |
| Bat__ | Unfortunatelly, when I try to send files via s3curl I'm getting Invalid URI message | 10:48 |
| Bat__ | The problem only occurs if I try to upload a file, lets say /a/b/c.txt to the bucket, in which tere are no subdirecotires "a" and "b" | 10:49 |
| Bat__ | This is a big problem for me, since S3 was accepting those requests without a problem | 10:49 |
| Bat__ | My sys admin tried to upload the same file without s3 middleware and he told me that the request was processed OK. | 10:50 |
| Bat__ | So it lookl like the python tier is somehow broken | 10:50 |

| RichiH | load balancing swift... we are pondering DNS RR or pushing everytihng through a central IP and abusing inbound nat. obviously, dns rr scales linearly while inbound nat can't scale indefinitely unless you do "geo" ip in your backbone or similar. (or source-based routing, which sucks) that is, unless it's possible to seperate singnalling and data transfer (i.e. you have one or two dispatchers which tell the clients which host to connct to to ... | 16:20 |
| RichiH | ... actually get the data) | 16:20 |
| RichiH | tl;dr: how are people load balancing swift? | 16:20 |

| kpepple | RichiH: it's an interesting way to do it without resorting to big iron LB ... but ospf can be a bear to configure/troubleshoot. depends on how much traffic, i suppose | 16:23 |
| RichiH | and what i don't get is how ospf equal cost routing helps at all | 16:23 |

| kbringard | I'd actually be very interested people's thought's on KVM vs Xen | 16:36 |
| diegoparrilla | vishy: mmm... I guess rattlesnake is somebody from my team that just left the channel... we are testing NFS and KVM live migration and we were wondering what is a better solution: NFS sharing or Glance copy-on-deploy approach | 16:36 |
| vishy | seems to be roughly split, kvm is way easier to install | 16:36 |

| katkee | we are studying OpenStack in order to migrate our current xen installation on it but it seems that OpenStack and XCP are overlapping themselves... We would prefer OpenStack to XCP but use Xen as a hypervisor. | 16:39 |
| kbringard | do we think the NaaS stuff is going to address that? | 16:39 |
| kbringard | secondly, if I heartbeat IPs and replicate IPtables and the dnsmasq files (leases, pids, etc... probably via NFS) | 16:39 |
| diegoparrilla | jaypipes: we were considering NFS shared approach for images enabling dedup and thin provisioing in the NexentaStor system | 16:40 |
| kbringard | any reason you can think of that wouldn't work for failover? | 16:40 |
| *** zenmatt has joined #openstack | 16:40 | |
| diegoparrilla | jaypipes: But glance is a better approach. And more resilient, probably | 16:40 |
| jaypipes | diegoparrilla: I'm not too familiar with the NexentaStor system, but you should still be able to use NFS with Glance's filesystem backend. Just set filesystem_store_datadir to point to the NFS mount... | 16:41 |
| kbringard | that's what I do, on a netapp | 16:41 |

| grapex | So I'm wanting to use Rackspace's internal DNS services which are very simple. I could do this from RedDwarf dbcontainer create call, but I need to store the association between an instance and DNS entry somewhere (heck, it might even be "extra" data for now). | 22:45 |
| Ryan_Lane | so nova wouldn't update DNS? | 22:46 |
| *** jonkelly has quit IRC | 22:46 | |
| Ryan_Lane | just store data in the database about what is in DNS? | 22:46 |
| grapex | It would be easier for us if it did, but we could work around it in the short term by putting code to do that in the dbcontainer portion of our API that piggybacks off the Nova compute stuff. We'd still need the association to persist somewhere though. | 22:48 |
| *** joearnold has joined #openstack | 22:48 | |
| Ryan_Lane | how is DNS itself not the association? | 22:48 |
| Ryan_Lane | you know the private IP address of the instance | 22:48 |
| Ryan_Lane | by doing a reverse lookup you have the entry | 22:48 |
| Ryan_Lane | or were you saying it would be easier if nova updated DNS? | 22:49 |
| *** icarus901 has joined #openstack | 22:51 | |
| Ryan_Lane | are instance names unique? or only the instance id? | 22:51 |
| Ryan_Lane | I guess I could test that really quick :) | 22:51 |
| grapex | True, but if the instance got blown away the IP address would be gone. Then again if the DNS association was in the DB it'd probably disappear too- I think you're right, it may not be needed. If Nova updated DNS it would still be nice. Maybe even that isn't needed. | 22:51 |
| Ryan_Lane | I'm proposing nova manage the DNS entries | 22:51 |
| *** patcoll has quit IRC | 22:52 | |
| Ryan_Lane | that way if you create an instance, a DNS entry is added, and if you delete an instance, the DNS entry is also removed | 22:52 |
| grapex | I think thats a great idea. | 22:53 |
| Ryan_Lane | the way I'm going to propose won't require schema changes | 22:53 |
| *** tblamer has quit IRC | 22:53 | |
| Ryan_Lane | which is a plus, because I don't understand how that part of the code works :D | 22:54 |
| * Ryan_Lane never uses ORMs | 22:54 | |
| *** joearnold has quit IRC | 22:55 | |
| grapex | Yeah, now that I think about it putting another association in the db between an instance and DNS doesn't help anything at all as long as you have a way of knowing when the DNS stuff needs to change. | 22:56 |
| Ryan_Lane | well, the good thing is that you can always use the IP address to find the entry | 22:57 |
| Ryan_Lane | so deleting the entries is easy | 22:57 |
| Ryan_Lane | no database needed | 22:57 |
| Ryan_Lane | public DNS is more difficult, because an IP address can be in multiple entries ;) | 22:57 |
| Ryan_Lane | but nothing requires association in a database | 22:58 |
| Ryan_Lane | hmm. public DNS should likely allow multiple DNS zones too | 22:59 |

| grapex | So I was wrong- internally we can't depend on looking up the entry via IP for whatever reason so I think our application needs the association. We could get by just stashing it as meta data somewhere though, even if we had to just decorate the DNS driver based system you're proposing to do it. | 23:34 |
| grapex | Anyway, thanks for starting the blueprint. I look forward to talking more about it tomorrow. | 23:34 |
