Funnnnyand if it's not, is there any plan to support ?10:08

uvirtbotNew bug: #800593 in nova "Flash websocket emulation doesn't work with nova-vncproxy" [Undecided,New] https://launchpad.net/bugs/80059310:11
ccookeFunnnny: openstack does support xenserver as a hypervisor10:15
Funnnnyccooke: thanks, is there any document on it, I can't find any10:16
ccookeFunnnny: http://wiki.openstack.org/XenServerDevelopment10:17
*** kashyap has quit IRC10:17
*** kashyap has joined #openstack10:17
Funnnnyccooke: is document there seems to be wrong, XenServer use yum not apt-get10:18
FunnnnyI'm confusing10:18
bonzayFunnnny: thats a "documentation error"10:18
ccookeFunnnny: it wants you to do that in a VM on the hypervisor10:18
bonzayyou need to do these commands _inside_ the compute-node in a ubuntu.-vm10:19
*** adjohn has quit IRC10:19
ccookeBasically, in order for OpenStack to inject VM images into the system it needs access to the hypervisor internals. There's currently no clean way to do that on the hypervisor dom0, so it's donein domU10:19
bonzayccooke: but this is very confusing for a beginner, I had the same problems understanding as Funnnny10:20
ccooke(I have a half-finished package that does it for dom0, but that was for my employer and I'm on a different project for the moment)10:20
Funnnnyso we must create a domU and follow the prepare nova part10:20
Funnnnyand then do the rest with XenServer10:21
ccookebonzay: Myself also. At least the document now *says* you need to do it inside a VM. When I started working with this, it didn't say that much :-)10:21
bonzayccooke: at least :)10:22
* ccooke is slightly frustrated; I have an alternate method for getting this to work which is much nicer, but I don't actually have time to do any work on it right now10:22
FunnnnyI'm taking a research to choose OpenNebula or OpenStack10:23
ccooke(note that I am not affiliated with openstack myself; I'm just someone using it)10:23
bonzayccooke: will you share your method?10:23
Funnnnybut seems that those two both are more nicely fit to a "workload", rather than a virtual infrastructure10:23
ccookebonzay: absolutely10:23
ccookebonzay: it's really a managed, packaged chroot image.10:24
ccookeit's nice and clean and comes as a single file10:24
ccookethere are, however, a couple of issues I need to deal with to make it work cleanly10:24
bonzayccooke: is it a .deb package you need to install in domU?10:25
ccookean rpm for the xenserver dom0, actually10:26
ccookemuch cleaner10:26
bonzayi agree10:26
bonzayso you dont need the domU then?10:26
ccookeYou currently do10:26
*** Fusion[SSP] has joined #openstack10:26
ccookebecause the dom0 option requires me to document and fix a couple of bugs in openstack10:27
shrii[15:26] <shrii> i am getting some issue with openstack-dashboard, [15:27] <shrii> not connecting to database.10:27
bonzaybut with your script you wont need it, right?10:27
bonzays/script/package10:27
ccookeAye. I expect I'll get time to work on that in a few weeks.10:27
ccookeHowever, that is just my option - it might turn out a bad one for openstack as a whole10:27
ccookeBut hey, it will make me *much* happier with the xenserver support10:28
ccookea domU is... messy10:28
bonzayyep, totally agreed10:28
ccookeAnd involves violation of levels of access/control10:29
bonzayI am very interested in a clean version of xen-server support10:29
bonzayso keep us informed :)10:29
ccookeWill do.10:30
bonzaythx10:30
ccookeI *have* had permission to share the implementation once it's actually usable, which is nice (since I'm doing it on work time)10:30
Funnnnyccooke: did you make xenserver usable with openstack dashboard10:31
*** jtimberman has quit IRC10:32
ccookeFunnnny: Yes... with the proviso that creating VMs doesn't actually *work* yet10:32
ccooke(All the issues are with the compute node, though: it was working absolutely fine with the dashboard)10:32
Funnnnyccooke: so it's the problem with compute node right now ? can we solve it yet ?10:33
ccookeFunnnny: the problem is specific to my implementation10:34
ccookeXenserver is fine with openstack if you follow the (not very clear, admittedly) instructions in the XenServerDevelopment page10:34
Funnnnyccooke: Thanks for your help10:35
ccookeNo problem. I wish it had been in a few weeks time, when I could offer something that's easier ;-)10:35
Funnnnyanother things, can I use XenCenter to manage the VM10:38
Funnnnyand then migrate to openstack when I setup and get the feature run nicely10:39
Funnnnyccooke: or I have to convert and register the VM to openstack10:39
*** katkee has joined #openstack10:40
ccookeIt would technically be possible to migrate the VMs to openstack, but I'm unaware of any way to do so at the moment. It could certainly be scripted, although there are fairly complex details to work out10:41
Funnnnyccooke: btw openstack is more like a workload cloud, than a virtual infrastructure management right ?10:43
FunnnnyI'm not sure about the lifecycle of the VM in openstack10:43
*** bonzay_ has joined #openstack10:46
ccookeI'm not sure what you mean10:47
Funnnnyccooke: I'm not so sure, as with my experience, I'm just testing both opennebula and openstack, when a VM restart or shutdown, it return to terminated state and cannot be start again10:49

aaronAUSit uses swauth (and SSL)13:11
*** jedi4ever has quit IRC13:11
aaronAUSso I was hoping it would work with cyberduck13:11
notmynameaaronAUS: you can use swauth, but swauth was just taken out of swift proper (it's its own project now). so that tutorial is slightly out of date. swauth can be found at http://github.com/gholt/swauth13:12
*** jedi4ever has joined #openstack13:12

NashTrashI have an instance with a public IP address.  If I try to ping that address from another instance within the cloud I get a time out.  If I ping the private IP it works just fine.14:24

Raziqueand the reste14:53
Raziquerest14:53
coggyRazique: is this current code from git?14:53
xxtjaxxRazique: Looking at the paste again it may be that the boot failed because it was trying to use the device(vda) and not a partition on the device like vda1. This explains the "unknown partitiontable" failure reported in this log.14:54
zobelxxtjaxx, Razique: what are you talking about? url to pastbin?14:55
Raziquezobel: na, I' explained him I was unable to create a squeeze ami14:56
xxtjaxxzobel: Razique tried to boot a Debian image with grub 2. This log http://paste.openstack.org/show/1641/ entails his misfortune at this endeavour.14:56
RaziqueI had an error during the instanciation process14:56
zobelxxtjaxx: unknown partitiontable may mean that there is no partition table at all.14:58
zobelon the other hand...14:58
zobelRazique: it reads like the mount-all.sh tries to mount a device that is non-existing14:58
zobelline 238 reads as there is an error while mounting.15:00

Raziquezobel: already tried :)15:06
Raziqueby modifying the /etc/fstab file15:06
zobelRazique: no, in your grub15:06
zobelits grub that passes root= to the kernel/initrd15:07

coggyRazique: it's this version: https://github.com/4P/openstack-dashboard/blob/master/openstack-dashboard/local/local_settings.py.example15:07
zobelRazique: if that works, you should be able to start your vm, but will need to adjust /etc/fstab afterwards, and then rebuild your initrd15:08
coggyRazique: never mind. I added the missing configuration manually and it seems to work just fine. Thank you15:09

CatKillerheckj: Thanks, I figured out15:55

CatKillerheckj: The DB is created with sqlachemy.migrate using a migration repo, and the models.py just defines the object model to match the db15:55
CatKillerheckj: The models is used internally in nova while the migrate defines the tables. Technically it could take the table definition from the models.py classes but then you'd lose the versioning capability.15:56

adam_gbodepd: if thats the case, i think the best would be bind database migration/sync to some component of the controller since installations might be depending on an external db instance outside the scope of puppet16:21
heckjYou might riff off the nova.sh script I just mentioned and install the base packages into the OS from that - it'll be reasonably quick16:21

qheadhey.. I'm researching distributed file storage systems and found Swift.. from the website I got the impression that Proxy Server is SPOF in the system?17:41

WormMan(from what I've read)17:42
qheadah, ok17:42
qheadI'm currently trying to decide whether to use Riak's Luwak or Swift17:42
NashTrashBe aware that Swift is not a "file system".  It just has buckets and blobs inside the buckets.  If you need a true filesystem look at things like ceph, MooseFS, Gluster, Lustre, etc.17:43
qheadYeah, I knew that, poor choice of words from my part :/17:44

heckjqhead: you can load balance the proxy servers - and there's a general rule of thumb that you want 1 proxy server for every ~8 storage servers18:00
heckjNashTrash: yeah, I'm afraid so18:01
*** ziyadb_ has quit IRC18:01
heckjNashTrash - nova-network manages that routing (and is the bottleneck) in the system today18:02
heckjCatKiller - there's a nova-api client library - I believe Dashboard uses it18:02
NashTrashheckj: Yeah, I know.  But, right now if I try to ping from one VM to another using the pubic IP it fails.  Ping with the private IP works.  Is this expected?18:03

*** obino1 has joined #openstack18:03
huslageNashTrash: if the IPs are on the same host then it won't work to talk between the public IPs18:04

heckjgithub link is broken on PyPi - source is here: https://github.com/rackspace/python-novaclient18:05
CatKillerheckj: Thanks, that sounds ok. I guess the issue is that there are so many tools/api that I don't know which is the "best" or the most relevant18:07
CatKillerheckj: For instance I had started using euca2ools in python too18:07

heckjDavor: are you getting no route to host when you try?23:00

Davor`heckj: I'm pretty sure eth0 is bound to br100. I'm able to ping its "management network" IP from the compute node23:02
Davor`heckj: ah right, that's how it looks from ip addr show: http://pastebin.com/G7Hasenm23:04
*** rnirmal has quit IRC23:05
Davor`heckj: br100 is bound to eth0's MAC and shows IPs on both the management (192.168.11.1) and VM (10.0.1.1) subnets23:05

heckjDavor: I'm at a loss beyond here - my IPTables foo isn't cutting this, from what I can see, that node should be completely able to ping 10.0.1.223:07

Davor`heckj: No worries, thanks for trying. Do you have any suggestions for how I can further debug this? Any logging I can turn on?23:13
Davor`heckj: Oh, and one more thing-- how come the log file for the instance is empty? (length 0)23:13
Davor`btw, I started LP question 159198 to figure this out23:14

Davor`heckj: and I noticed that I have two identical dnsmasq processes running23:15
Davor`except for the PID, both have the same parameters in 'ps ax' output:  1495 ?        S      0:02 dnsmasq --strict-order --bind-interfaces --conf-file= --domain=novalocal --pid-file=/var/lib/nova/networks/nova-br100.pid --listen-address=10.0.1.1 --except-interface=lo --dhcp-range=10.0.0.2,static,120s --dhcp-lease-max=32 --dhcp-hostsfile=/var/lib/nova/networks/nova-br100.conf --dhcp-script=/usr/bin/nova-dhcpbridge --lea23:15
Davor`sefile-ro23:15
heckjDavor: you probably want to kill one of those DNSMASQ processes, but that shouldn't stop the networking.23:15
heckjDavor: not sure about the log file either - nova is mostly set to scroll output to the console from each process, but can be configured to log to a file. And I'm learning the debugging of the networking stuff right now - so I'm afraid I don't have much idea of where to go next except to ask others on this channel.23:17
Ryan_LaneDavor`: one of them is the parent of the other23:17
Davor`Ryan_Lane: so I shouldn't touch either?23:18
*** msinhore1 has quit IRC23:18
Ryan_Lanecorrect. unless they need to be restarted because your configuration changed and the dnsmasq process has the incorrect info23:18
Ryan_Lanein that case you'd kill both and restart nova-network23:19
Ryan_LaneDavor`: you are using the ubuntu packages?23:19
Ryan_Lanethe cactus release?23:19
Davor`Ryan_Lane: and there is a third one, comming from libvirt, but listening on a different IP and for a different DHCP range23:19
*** MarkAtwood has joined #openstack23:19
Davor`Ryan_Lane: that's correct. Ubuntu Natty server, cactus release23:19
Ryan_Lane*that* one needs to die23:19
Ryan_Laneso...23:19
Ryan_Lane /etc/init.d/dnsmasq stop23:20
Davor`Ryan_Lane: there is no /etc/init.d/dnsmasq23:20
Ryan_Laneeh? really?23:20
Ryan_Laneah. right23:21
Ryan_Lanedo this, then: stop dnsmasq23:21
Ryan_Lanestupid upstart23:21
Ryan_Laneyou'll also need to disable dnsmasq in the upstart file23:21
Davor`Ryan_Lane: no such luck -- "stop: Unknown job: dnsmasq"23:21
Ryan_Lanethat's odd. dnsmasq must be installed. that usually installs an init script too23:22
Ryan_Lanesomehow that 3rd process is getting started23:22
