dubsquaredanyone around this evening?01:12
kstewardI am01:12
kstewarddubsquared: are you a regular here?01:13
kstewarda question for the group...01:14
dubsquaredgoing to be, just getting heavily involved with openstack at work01:14
kstewardwhat's the best way to try OS out?   Will one server or two servers be needed?01:14
kstewardmore than two needed?01:15
kstewarddubsquared: where do you work?01:15
dubsquared  — anyone seen the resolution to this01:15
dubsquaredmy /tmp is writable, and all services are started01:16
dubsquaredi work at Rackspace01:16
kstewardah, the central instigators of OS01:17
kstewardnice that Rackspace took the leadership role and got OS going01:17
*** chmouel has quit IRC01:17
dubsquaredAh, it wasn't just us….many many many folks :D01:17
kstewardright, but it sounded like you guys started the ball rolling, right?01:18
*** rsampaio has quit IRC01:18
dubsquaredOpenstack came from the Rackspace Cloud Files (Swift), and NASA's nebula project (Nove)01:18
kstewarddubsquared: did you attend the Design Summit?  If so, how was it?01:18
dubsquarednebula is built on KVM, and Rackspace Cloud is Xen based atm...01:19
dubsquaredthere is a lot of work that is going into the dev of OpenStack, as Rackspace will eventually be running it in our production env once it's more mature01:19
dubsquaredI did attend, it was very, very, informative!01:20
kstewardlots of enthusiasm and momentum building?01:20
dubsquaredMet a lot of good folks, and def seeing the rally come together01:20
dubsquaredYep :)01:20
*** chmouel has joined #openstack01:20
kstewardwhat other big name companies besides Citrix, Dell were there showing support?01:20
dubsquaredNTT from Japan had quite a few folks in town, RedHat and Ubuntu had a pretty good showing01:21
kstewardIntel too, i belive01:21
dubsquaredI didn't meet anyone from there, but there were hundreds there, probably so01:22
kstewardso... do you think Amazon will eventually support OS?01:22
dubsquaredpersonally, yes01:22
kstewardwhat about Microsoft?  Will they abandon Azure in favor of OS?01:23
dubsquaredNot likely, but they did recently say that HyperV was on-board for OS dev01:23
dubsquaredI'm pretty excited to see how that works into future integration01:24
kstewardI personally think Azure is doomed.  I heard that only 50 customers are on it.  And Ray Ozzie, the CTO who led the dev of Azure, has stepped down recently.01:24
dubsquaredThat will really scale the reach of OS int'lly01:24
dubsquaredYeah, I'm shocked that Ozzie is out!01:24
dubsquaredMS leadership is running out of ppl :)01:24
kstewardand MS isn't replacing him with another CTO01:24
kstewardtheir proprietary operating system under / in the cloud will be an expense and lock in that people will avoid like the plaque01:25
kstewardnot to mention the unreliability of a Window's operating system will only reduce interest in their cloud.01:26
dubsquaredHonestly, MS doesn't make 'bad' products...01:27
dubsquaredbut you're spot on with the vendor lock in scares01:28
kstewardwell I'm not impressed at all with Windows 7 64-bit .... I'm suffering with that at work01:28
dubsquaredI think that familiarity that HyperV brings to the table, and being able to integrate that HV into OS will really help MS scale into parts of the cloud possibly previously untouched01:29
kstewardI'd much prefer a LINUX machine, but the company doesn't support that (yet)01:29
*** hornbeck has joined #openstack01:29
kstewardso what happened to the other open cloud effort (CCID i think it was called)?01:30
kstewardit was started about a year ago with some fanfare and then fizzled?  Any of that work move over into OS?01:30

dubsquaredany more insight into that vishy?03:00
vishydubsquared: is thare a openssl.cnf in your CA dir?03:05
dubsquaredwhere/what step is that gen'd03:07
dubsquaredI'm rolling with these, "" and taking notes in what needs to be updated03:09
*** sirp1 has quit IRC03:25
vishythat should get run automatically with genrootca.sh03:30
vishywhich runs on start of nova-api03:32
vishydubsquared: did you guys ever get a working centos image?03:32
vishyi'm downloading some iso's to make one03:33
dubsquaredyeah, it appears that my nova-api is not starting03:34
dubsquaredand on the centOS image, no, we tried 3 and got a similar error on each03:34
dubsquaredwe could get all the way to the bundle part, through enc… part.X......03:34
dubsquaredthen we'd get an error 'expecting:CERTIFICATE' etc etc03:35
dubsquaredi have the error sitting around here somewhere…ill look for in a sec03:35
dubsquaredIOError: [Errno 2] No such file or directory: '/usr/lib/pymodules/python2.6/nova/virt/libvirt.rescue.qemu.xml.template'03:35
dubsquaredso all these files are showing up missing03:35
dubsquaredin our working cluster, i see those files exist03:35
dubsquaredi don't know where they came from thou :|03:36
vishydubsquared: people were reporting some files were missing03:36
vishyfrom austin03:36
vishythey are in trunk though03:36
dubsquaredwell i think I found two of them03:37
dubsquaredah, i think i recall Jordan saying something about that03:37
vishydubsquared: so the bundle image was working?03:37
vishy* not working03:37
dubsquaredit's start, format the filesystem, start creating the image, then spit out all the "part.X's"03:38
dubsquaredthen error right after that03:38 will grab from trunk?03:38
dubsquaredor what it the easiest way to get these missing bad boyus03:39
vishydubsquared: so the euca-bundle doesn't work on centos properly?03:39
vishymight have to use ec2-bundle :(03:39
dubsquaredyeah, that is #2 on my 'stuff to try' list03:40
dubsquaredgetting another image, from boxen is 1st03:40
dubsquaredi keep getting them from the net03:40
vishyi need a centos image by tomorrow, so i'm going to try it03:41
dubsquaredhaha nice03:43
dubsquarednothing like a little deadline to push the boundaries of "try harder"03:43
vishyunfortunately i've never actually used centos, so this could be exciting03:44
dubsquaredthat's how i felt installing on 10.04 ubuntu world03:44
dubsquaredi typed 'yum apt-get' a few times on accident when i first started...03:45

dubsquaredit's aight….not quite done04:06
dubsquaredi think i ran into the 'missing files' issue04:06
dubsquarednova-api is not starting04:06

dubsquaredand due to that, i cant run my command to get my nova.zip04:06
JordanRinkeand it will spit the error to screen04:06
JordanRinkewhich tells you what file is missing04:07

alekibangoannegentle: your screencast ended in a strange way. missing command 'killall'  went through the screen and right then you stopped the video. You should show how to navigate in those few screens to read logs (ctrl-a ctrl-n, ctrl-a "   etc)04:16
alekibangoand running few commands  would be also nice04:16

HUif i have install proxy and auth server in one machine 1, and install another proxy server in machine 2, how to configure "default_cluster_url"  of auth-server.conf?08:29
JordanRinkei would try setting it to the ip of machine 108:30
HUso no special setting for the second proxy server , just config it as proxy 1 and start the service, right?08:31
anticwHU: we run multiple proxies for performance reasons08:37
JordanRinkeyey, there you go... someone who knows for sure :D08:39
anticwyou also want to bump the # of workers up to something like 2x the number of cores on the system08:39

sandywalshhi y'all ... trying to get nova running on clean ubuntu 10.10 64bit install, but running into an issue with rabbitmq16:49
JordanRinkewhats wrong?16:50
sandywalshit hangs on "starting rabbitmq" after apt-get install16:50
tr3buchetyou've b een to texas recently havent' you sandy!16:50
sandywalshmy ps -aux list looks like
sandywalshthe rabbit archives suggest there's already a copy running, but I've killed off all the processes and tried again ... same problem16:50
sandywalshit works fine on 10.10 32 bit16:51
JordanRinkeive done it on a 10.10 64bit build16:51
gundlachsandywalsh: is that 10.10-64 on metal or virtualized?16:51
sandywalshvirtual on vmware16:51
sandywalsh10.10 server (I should be clear)16:52
sandywalshI've posted this in the #rabbitmq room, no response yet.16:52
JordanRinkefor the sake of time/reset etc do you have anything against just doing a dpkg -P rabbitmq-server, rebooting and installing it again?16:53
sandywalshnope ... I'll give it a shot ... sec16:54
sandywalshhmm, that worked ... odd. Thanks JordanRinke!16:56
JordanRinkeno problem, I did a 40 node install and once or twice just had some random package issues16:57
JordanRinkefound the easiest way was to reset it, if the problem still existed, dive in to it16:57
sandywalsh:) makes sense16:58

pikenhow hard is it to modify nova-compute to spawn custom vm instances that do not use the network manager, but spawn with given ip addresses?17:01
creihtmtaylor: ping17:02
pikenwe are looking at switching to sr-iov for infiniband to do pure device virtualzation for pure ib in the vm's.17:02
creihtmtaylor: you probably know what I'm going to ask about... :)17:02
JordanRinkeif you use the flatnetwork manage17:02
JordanRinkeit injects the IP from the DB and lets them go17:02
JordanRinkeI used that last week, gave all my VMs a public IP on a flat VLAN'd switch17:03
pikenI understand that, but in this setup, we can't have bridges as you can't bridge a 20byte mac network.17:03
JordanRinkeah I gotcha17:03
pikenwe are doing some weird things to get it now, but sr-iov with virtualized ib will double network performance.17:03
mtaylorcreiht: yes! will do as soon as I reboot after changing laptop batteries...17:05
creihtmtaylor: and thanks :)17:05
JordanRinkepiken: my bet is the best person to answer that question would be vishy17:06
pikenI will have to chat with him. Because if I do the work for it. I will make sure we can submit it back to have openstack as the first sr-iov supported cloud stack.17:07
annegentleI'm working on a man page for nova, but I'm not sure where it would be stored - tools? how would it get to the right location when someone installs?17:09

annegentleeday: that would also be logical :)17:22
sandywalshhmm, this rabbitmq issue seems to be related to changing the hostname17:22
annegentleeday: one thing I don't understand is, how does the file gets to the /usr/ directory?17:23
JordanRinkethe package would do it17:23
annegentleJordanRinke: ok, do I need to notify mtaylor once it's done?17:24

mtaylorannegentle: that's right!17:26
*** Cromulent has quit IRC17:26
annegentlethanks all17:26
mtaylorannegentle: oh - what I meant was doc/source/conf.py17:27
mtaylorannegentle: see man_pages = in the swift docs17:27
annegentlemtaylor: ok17:27
annegentlemtaylor: oh good an example17:28
mtaylorannegentle: hrm. I may be lying to you...17:29
annegentlemtaylor: yeah I don't see one in swift yet17:29
mtaylorannegentle: in fact, it does appear that there are none in nova or swift :)17:29
annegentlemtaylor: exactly the opportunity I need on a Monday :)17:30
alekibangoman pages are needed17:30
alekibangoeven simple ones17:30
alekibangocould make it much better17:30
mtaylorannegentle: so - you want to add an entry to that looks like this:17:30
mtaylorannegentle: with one entry per manpage... the fields are (location_of_rst_file, man_page_name, man_page_title, author, section)17:32
annegentlemtaylor: ok, got it. I'll start with nova-manage (there are other nova commands but seems like a good starting point)17:32
JordanRinkeit would be nice to have a man page for each service that explains what flags they service takes in its .conf file17:34
JordanRinkeand if it depends on any other services to be running17:34
*** colinnich has quit IRC17:35
annegentleJordanRinke: yeah good idea, a way to connect-the-dots back to the flag files17:36
pikendo the components currently check to see if there is a config file for it in /etc/nova?17:37
*** dubs has joined #openstack17:37
pikenlike /etc/nova/nova-compute.conf for nova-compute17:37
JordanRinkeif you run them using the service controller, it sets the flag file17:37
JordanRinkeif it doesnt exist it just uses defaults and pukes all over itself17:37
pikenyeah, and that is only there in the ubuntu service files.17:37
JordanRinkeso i think the answer is no, but that is by design17:39
JordanRinkesince you can throw all the flags into the commandline if you want17:39

Ryan_Laneis there a guide somewhere for creating VMs for use with nova?18:55
*** grizzletooth has left #openstack18:56
JordanRinkeRyan_Lane: not that I have seen but it is needed18:57
JordanRinkeif you can find guides related to euca2ools those will work18:57
xtoddxRyan_Lane: do you mean installing nova inside a VM, or launching a vm within nova?18:58
Ryan_Lanewell, I made an image using vmbuilder, but I also need the ramdisk and kernel somehow18:58
jaypipesRyan_Lane: yes, right now only AMIs are supported, so you can use the Amazon docs in a pinch.18:58
Ryan_Laneah. ok. amazon docs will do18:58
jaypipesxtoddx: or do we support raw images now?  not sure that patch made it in...18:58

jaypipesRyan_Lane: feel free to create a page on the wiki for that and we can work as a community to add in "factory" images.18:59
xtoddxi think vishy's script also grabs some images18:59
JordanRinkeRyan_Lane: here is a guide I used over the weekend18:59
Ryan_Laneyeah, the images it grabs are the tiny ones18:59
jaypipesxtoddx: just the tiny one AFAIK.18:59
Ryan_Laneand the tiny one doesn't work with injected IPs19:00
JordanRinkeit is not exactly relevant, but all the commands at the end are useful19:00
JordanRinkei used this guide to make an ubuntu image from a running box19:00
Ryan_Lanein fact, the tiny one totally breaks when using flatnetworking (I submitted a patch for this)19:00

JordanRinkeI will have to check with Piatt but I am almost certain all the gear dubsquared just got was for community openstack labs19:12
JordanRinkei don't know what he is planning to do in terms of swift/nova deployment etc19:12
jaypipesJordanRinke: should I still ask john purrier to get hardware allocated, or should I just talk to you guys?  Basically, all I need at first is one machine to run the test clients (CI program) and two other machines for the cloud (one for API/Scheduler/MQ) and another for compute/volume19:12
jaypipesJordanRinke: I'll check with john purrier on what he was planning, then, make sure I don't step on any toes.19:13
JordanRinkeI would say pop an email to him and Wayne Walls (dubsquared) to see what is up19:13

sandywalshHmm, trunk build. I run-instances and the instance seems to be stuck in "scheduling" ... no blatant errors in any of the service windows. virsh list is empty.20:50
sandywalshwhere's a n00b to go?20:51
sorenAre you running nova-schedule anywhere?20:51
sorenIf not, you should try it. It's all the rage.20:51
sandywalshnope, api, objectstore, compute and network20:51
sorenCan't schedule stuff without a scheduler. :)20:52
sorenWe really should add a timeout for that sort of thing.20:52
sandywalshah, I was just following a tutorial and didn't see any scheduler mentioned20:53
dendrobatesnew feature request: schedulerless scheduling20:53
sorensandywalsh: It wasn't always there. It used to live inside the api server.20:53
sorendendrobates: Not as crackpot of an idea as you may think :)20:53
sandywalshah, ok. any notes on that, I'll update the wiki20:53
dendrobatesI don't think it is a crackpot idea20:54
sorenWith certain restrictions, the message queue would make a very, very decent scheduler on its own.20:54
sandywalsh./bin/nova-schedule --flagfile=...  ???20:54
dendrobatesi agree, then let the nodes decide what to accept20:54
dendrobatessoren, any chance of you updating your blog post.20:55
sorendendrobates: Even better: Have separate topics for each VM size. If you can't handle a certain size, unsubscribe from it.20:55
sorendendrobates: that way, we don't even have to broadcast.20:55
JordanRinkesandywalsh: /bin/nova/nova-scheduler --flagfile=/etc/nova/nova-scheduler.conf (or wherever that file lives)20:56
dendrobatesthere are other things than size20:56
sorendendrobates: That's a muth.20:56
sorenOh, VM's?20:56
sandywalshJordanRinke, my nova-manage.conf is pretty basic ... are there special entries for scheduler?20:56
JordanRinkenot that I know of20:56
sandywalshI stated the scheduler and it doesn't seem to be picking up any jobs20:56
sorendendrobates: Right, those were the "certain restrictions" I was talking about.20:57
sorendendrobates: Well, some of them.20:57
sandywalshdoes the scheduler have to be running when the create request is first made?20:57
sorensandywalsh: I don't think so, no.20:57
sorensandywalsh: The request is probably sitting in the message queue, waiting to get delivered.20:57
JordanRinkesandywalsh: you need to have the basic stuff in it20:57

sandywalshswalsh@novadev:~/openstack/nova$ less /etc/nova/nova-manage.conf20:58
sandywalshsomething more?20:58
sorenAll that is just for nova-manage (which doesn't need most of it).20:59
sorenUnless, of course, you specifically point nova-scheduler at the same flagfile.20:59
sorennova-schedule, I mean.20:59

*** maple_bed has joined #openstack20:59
sandywalshshits and giggles20:59
sorenOh, those.20:59
sorenIt makes sense.21:00
sorenThings used to refuse to start if you passed unknown flags to them, so we had to have separate flagfiles for each worker.21:00
sorenNow they don't, so we should be able to use the same flagfile for everything.21:00
sandywalshso it seems to have picked up .../nova/nova.sqlite as the db and sqlalchemy as the backend, which seems fine.21:01
sorenthe flip side is that if you misspell sql_connection as "sql_conection" or whatnot, I can take a *looong* time to figure out why the bloody thing won't talk to your database.21:01
*** gundlach has quit IRC21:01

sorenBefore, you'd get an error about an unknown flag.21:01
sandywalshis there a wiki page on the scheduler config?21:01
sorenThere's really almost nothing to it.21:02
sorensql_connection and rabbit_host is all it needs to work.21:02
sandywalshdo you have a sample incantation?21:02
*** dizz|away has quit IRC21:02
sandywalshit's all on one machine, so it got rabbit correctly21:02
soren"nova-schedule --sql_connection=sqlite:////var/lib/nova/nova.sqlite" is what I use. It defaults to a local rabbit.21:03
sandywalshdoes scheduler pick jobs from the db or from the queue?21:03
sorenOh, it is actually nova-scheduler, not nova-schedule. Imagine that.21:03
sorensandywalsh: queue.21:03
sorensandywalsh: The api server collects the info from the request, puts it in the database, and sends a message that this particular VM needs scheduling.21:04
sorensandywalsh: So the bulk of the info is in the db, but the "scheduling job" I guess is a message queue thing.21:05
sandywalshok, I'll check that api and scheduler are using the same db. thanks soren!21:05
sorenNow that you've actually had a scheduler running, the message may have been received (and subsequentely dropped on the floor), so you may need to do another RunInstances.21:06

dragondmto be honest, I don't thing nova-volume is needed for basic function23:57

dubsquared1you can however, download the vanilla kernel source, and compile the modules separately23:57
