| *** miclorb has quit IRC | 08:55 | |
| soren | Not sure what you mean by "scp my.img euca-$tarball-$magic", but yeah, just upload it. | 08:55 |
| xxtjaxx | Okay. soren well upload it from my box to the cloud system them tarball/bundle it and start | 08:56 |
| soren | Right. | 08:57 |
| xxtjaxx | soren: Awesome thanks. | 08:57 |
| *** Eyk is now known as Eyk^off | 08:58 | |
| Razique | xxtjaxx: does your image uses grub2 ? | 08:58 |
| xxtjaxx | soren: Razique think so yes. | 08:59 |
| Razique | I found it very complicated with Grub2 actually | 08:59 |
| xxtjaxx | qcow2 format or raw? | 08:59 |
| Razique | raw | 08:59 |
| xxtjaxx | kk. I'll see and report back :) | 08:59 |
| *** eplaton has quit IRC | 09:00 | |
| Razique | When I'll have time, I'll work deeply on that, but few months back, I never figured out how to run custom images made from kvm | 09:00 |
| Razique | (using brub2) | 09:00 |
| soren | If you don't specify a kernel, it'll just boot the image directly. | 09:01 |
| soren | So it needs a bootloader. Like grub2. | 09:01 |
| soren | It should work. | 09:01 |
| soren | If it doesn't, that's a bug. | 09:01 |
| nicolas2b | hi, somebody got any hints about that problem https://answers.launchpad.net/nova/+question/169704 | 09:02 |
| nicolas2b | when trying to upload an image, got 403 forbidden by glance | 09:02 |
| Razique | soren: actually, as far as I remembered, Grub2 complained about a non existent disk, since disk names are not the same :) | 09:05 |
| Razique | I"ve tried for weeks running a grub2 image, without sucess :( | 09:06 |
| soren | Razique: Oh. | 09:06 |
| soren | virtio. | 09:06 |
| soren | Razique: Yeah, I can see why that might happen, actually. | 09:06 |
| Razique | soren: I haven't push my theory further due to lack of times, but I suppose this might work with a grub1 image | 09:07 |
| soren | The problem I'm thinking off will apply to both grub1 and grub2. | 09:10 |
| Razique | soren: I concluded on that, because all the images that are actually "instanciable" the ones I get from images.canonical.com | 09:11 |
| Razique | don't have grub2 installed | 09:11 |
| Razique | but I never found a Debian Squeeze image actually :) | 09:12 |

| Excds | Hi all. I have a bunch of newbie openstack questions... | 14:42 |
| Excds | 1: What happens when you launch an image? Do we copy the image from the storage controller, or do we use some kind of network storage? | 14:43 |
| Excds | 2: If network based, iscsi/nfs? | 14:43 |
| Excds | (the Google failed me...) | 14:44 |
| Razique | hi Excds : | 14:46 |
| Excds | ' | 14:46 |
| Excds | Hi. :-) | 14:46 |
| Razique | 1- The nova-compute caches the image locally from the SC | 14:46 |
| Razique | 2- so the instance runs independently from others components, except the nova-network one. | 14:47 |
| *** reed has joined #openstack | 14:47 | |
| Razique | 3- If you use nova-volumes (equivalent of Amazon S3), nova uses iscsi | 14:47 |
| Excds | Razique: So I can specify a nova-volume as backend? | 14:48 |
| Razique | Excds: sure :) | 14:48 |
| Excds | Razique: And also if I use that, then live migration wouldn't be a problem either... | 14:49 |
| Excds | Razique: Is it possible to specify which nova-compute node I start an instance on? | 14:49 |
| Razique | Excds: I've asked the same thing here : http://docs.openstack.org/cactus/openstack-compute/admin/content/live-migration-usage.html | 14:49 |
| Razique | Excds: no I don't think you can, but you can disable a compute node | 14:50 |
| Razique | so every time a compute node is chosen, you can "force" that | 14:50 |
| Excds | Razique: Disable as in "remove from available node hosts list" then? | 14:51 |
| Excds | Razique: Do I specify that an instance should use nova-volume storage when adding it to the cloud? | 14:52 |
| Razique | Excds: exactly, but, the node then becomes useless :p | 14:52 |
| Razique | Excds: no, not directly, you have to attach a volume to an instance after it's been instantiate for the first time; or well, if it's in a "running" state | 14:53 |
| Excds | Razique: Hmm, but I want the instances' root disks to be in a network storage. | 14:54 |
| Razique | Excds: This features exists, it's called a "boot from volume" It's still a blueprint ; https://blueprints.launchpad.net/nova/+spec/boot-from-volume | 14:55 |
| Razique | It's supposed to be an available feature for Diablo, (others, correct me if I'm wrong) | 14:55 |
| Excds | Razique: ok | 14:56 |
| Excds | Razique: Background: We've got 16 machines in our test cloud and we're currently hosting the xen images locally. When running like this (a bunch of virtual machines on each), we're getting a lot of iowait on the vm:s. | 14:56 |
| *** mnour has joined #openstack | 14:56 | |
| Excds | Razique: So the whole point is that I'm going to setup a new machine with a bunch of striped SSD disks as network storage, to hopefully remedy the situation. | 14:57 |
| Razique | what amount of iowait are we talking about here ? | 14:57 |
| Razique | 10% ; 90% ? | 14:57 |
| Excds | Razique: And that's also why I'm looking in to different cloud setups... But if openstack by default caches the image locally I would end up in the same situation again... | 14:58 |
| Razique | Excds: I've never had high loads on my current openstack arch, neither on the old one (using KVM + libvirt locally) | 14:58 |
| Razique | And I don't use SSD :) | 14:59 |
| Excds | Razique: It depends. We're simulating a network of service nodes with mysql/file/stuff-replication. The iowait can get up to 90%, yes. | 14:59 |
| Excds | Razique: And that makes it quite painful to wait while the test vm:s try to get into a proper state... | 15:00 |
| Razique | oh god :D | 15:00 |
| Razique | have you run an in-depth analysis ? | 15:00 |
| Razique | so you know what causes such load ? | 15:00 |
| Excds | Razique: 1: There is no god. 2: If there were, he would be crying due to the iowaits... | 15:00 |
| Razique | ahah, sure | 15:01 |
| Razique | Are the hypervisors well sized ? | 15:01 |
| Excds | Uhm, what do you mean? | 15:01 |
| Excds | Another thing, we want to be able to move images between machines a little faster. So that's why networked storage would be better. | 15:02 |
| Razique | I mean, are the iowaits on the hypervisors themselves or on the VMs ? | 15:02 |
| Excds | There's iowait on the host machines as well as the vm machines. One causes the other... | 15:03 |
| *** huslage has quit IRC | 15:03 | |
| *** caribou has quit IRC | 15:03 | |
| Razique | You could use a SAN storage for backend, so physically, the images are on the san, whatever which server is using them | 15:03 |
| Excds | That's the plan, to setup this new machine as an iscsi target. | 15:04 |
| Razique | well, you could, that is what I do, the whole openstack arch. is located into a SAN | 15:04 |
| Razique | regarding you iowaits, It could be anything actually, | 15:04 |
| Excds | Hmm, but what about this image caching? | 15:04 |
| *** reidrac has quit IRC | 15:05 | |
| Razique | not specifically the virt. tech. | 15:05 |
| Excds | Uhm, what? | 15:05 |
| Razique | ah yes, get what you mean. when you run an instance, the compute node uses a local image yes | 15:06 |
| Excds | Yes | 15:06 |
| Razique | it's that one which is used :) | 15:06 |
| *** nid0 has quit IRC | 15:06 | |
| *** hadrian has joined #openstack | 15:06 | |
| Excds | Hmm, well, I guess we could continue using the current setup. My question then is if it's possible to have 16 machines accessing the same iscsi target? | 15:07 |
| Razique | are you 16 machines hypervisors or VMs ? | 15:08 |
| Excds | 16 hypervisors running at least two VMs each. | 15:09 |
| Razique | from an openstack view, you won't have 16 iscsi targets, only the ones running nova-volumes will use it | 15:09 |
| Excds | So, if I would continue using just disk images but iSCSI as backend for the hypervisors. | 15:09 |
| Razique | yup | 15:09 |
| Excds | I definitely have to read some more... | 15:11 |
| Excds | Thanks a lot Razique! :-) | 15:11 |

| jano | When attempting to instantiate a server, I'm running into http://paste.openstack.org/show/2360/. Basically boils down to an attempt to create /var/run/sr-mount/f28c3c6e-154a-7129-1033-d5718a2057f0/tmpt6XRFX, where the parent directory doesn't exist. Where would nova get this uuid from? | 15:21 |
| *** jedi4ever has joined #openstack | 15:21 | |
| Razique | jano: not an xen user, but I see this : No such file or directory: \'/var/run/sr-mount/ | 15:22 |
| Razique | maybe it's a hint | 15:22 |
| *** HowardRoark has joined #openstack | 15:23 | |
| jano | That directory exists, but the one below it doesn't: /var/run/sr-mount/f28c3c6e-154a-7129-1033-d5718a2057f0 | 15:23 |
| jano | I could manually create it, but that seems wrong. | 15:23 |
| Razique | I think so yes | 15:23 |
| *** hadrian has quit IRC | 15:24 | |
| *** nerens has quit IRC | 15:26 | |
| jano | The plot thickens: /var/run/sr-mount/02eb3381-a78b-44f3-abcd-f2cc43f2b7d7 exists and is the mount point for the local sr storage. That's the one Nova should use I suspect. | 15:26 |
| *** osier has quit IRC | 15:31 | |

| nicholi | hopefully simple question, how do i convert the private ssh key (which is injected into each guest vm) to a ppk so it can be used in putty? | 21:37 |
| *** woleium has quit IRC | 21:38 | |
| nicholi | i tried using the puttygen application, but it will not load the key in order to convert it | 21:38 |
| nicholi | which is the part i'm bamboozled at... because using the key with ssh -i 'mykey' will work just fine | 21:43 |
| *** Ryan_Lane has quit IRC | 21:44 | |
| jcapel | nicholi: if you go conversions -> import key in puttygen you can import an openssh rsa private key file | 21:46 |
| jcapel | and then use the "save private key" button to save the .ppk | 21:46 |
| nicholi | thats what i mean, it won't load the key when i try to import it | 21:46 |
| nicholi | trying the *nix version of putty-tools now | 21:47 |
| *** Ryan_Lane has joined #openstack | 21:47 | |
| nicholi | it returns "Couldn't load private key (unexpected end of file)" | 21:47 |
| nicholi | and i tried making sure there was an empty newline at end...only thing i've seen mentinoed | 21:47 |
| jcapel | maybe some windows / *nix newline mismatch... otherwise I have no idea | 21:48 |
| nicholi | yeah i donno, have you ever tried actually converting the key generated from euca-add-keypair though? | 21:54 |
| nicholi | as i thought maybe it was something like that too...forced to cr/lf, just lf... but nothing | 21:54 |
| nicholi | and i generated another key with ssh-keygen just to make sure i wasn't crazy...and it imported just fine | 21:54 |
| nicholi | man...even the linux version isn't working | 21:57 |
| nicholi | $ puttygen ./openstack.pem -O private -o ./openstack.ppk | 21:57 |
| nicholi | puttygen: unable to load file `./openstack.pem': not a private key | 21:57 |
