| fernandofat | hi there | 01:58 |
|---|---|---|
| fernandofat | I have a question regarding scaling up resources like memory on UEC vm's | 01:59 |
| fernandofat | how does this work? | 02:02 |
| === dendro-afk is now known as dendrobates | ||
| smoser | in UEC there is no way to scale memory up | 02:15 |
| smoser | general idea of "cloud" is horizontal scaling | 02:15 |
| flaccid | well different instance types can have different amounts of memory | 02:16 |
| flaccid | you can vertical scale mem and cpu | 02:16 |
| smoser | right.. i was thinking that the quesiton was regarding an existing (running) instance | 02:17 |
| smoser | ie, hotplug memory | 02:17 |
| flaccid | that would be nice :) | 02:17 |
| fernandofat | okay, so horizontal scaling would be creating a copy of the running vm and they would work as one? | 02:20 |
| fernandofat | smoser, it is regarding an exising instance | 02:20 |
| flaccid | depends what you are serving - if its scalable e.g. an application server behind a frontend lb | 02:21 |
| fernandofat | a squid proxy server for example | 02:21 |
| flaccid | multiple backend proxies can work like that | 02:22 |
| fernandofat | is it correct what I said? about two virtual machines working as one? regarding horizontal scalability | 02:25 |
| flaccid | no | 02:25 |
| flaccid | two or more separate instances | 02:25 |
| fernandofat | so for scaling up what gets replicated are the instances | 02:30 |
| flaccid | in a general sense, yes | 02:31 |
| fernandofat | nice | 02:31 |
| erichammond | It's not quite hotplug (requires reboot) but on EC2 you can scale up and down a single instance: http://alestic.com/2011/02/ec2-change-type | 02:38 |
| erichammond | Don't know about UEC. | 02:38 |
| fernandofat | where can I find some practical information on private cloud/UEC? Like what I can and what I can not do with this technology? | 02:44 |
| flaccid | see the topic | 02:44 |
| flaccid | and euca docs | 02:44 |
| smoser | UEC does not provide ebs root, and somewhat as a result, does not allow StopInstance | 02:45 |
| fernandofat | ok, thanks for the answers. I'll check out the euca docs, I already saw the Cloud Portal docs. | 02:52 |

| kim0 | Morning o/ | 08:03 |
| rwat | Hi cloud people - playing with my first cloud setup and failing to get an image running. What's the secret of how to get a emi when you upload an image bundle? | 10:48 |
| koolhead17 | rwat, what is the cloud controller? | 10:51 |
| === nijaba_afk is now known as nijaba | ||
| rwat | koolhead17: I'm using eucalyptus-cc 2.0.1 on natty, if that's what you mean | 10:53 |
| koolhead17 | rwat, http://cssoss.files.wordpress.com/2010/12/eucabookv2-0.pdf see if this helps. | 10:55 |
| koolhead17 | kim0, there | 10:56 |
| kim0 | here | 10:56 |
| koolhead17 | can we change topic and put this book link there? | 10:56 |
| kim0 | Yeah why not :) | 10:56 |
| kim0 | let me shorten it though | 10:56 |
| rwat | yeah that looks useful | 10:57 |
| koolhead17 | yeah sure | 10:57 |
| * koolhead17 thinks of updating it 4 natty soon. | 10:57 | |
| rwat | when I try to activate an image from the store I just get "Bad request signature" | 10:59 |
| rwat | no indication of what bit of the cloud thinks the request has a bad signature | 10:59 |
| === kim0 changed the topic of #ubuntu-cloud to: All questions relating to Ubuntu Enterprise Cloud (UEC), Ubuntu over EC2, cloud configuration management tools are welcome | Ask clearly, and wait patiently for an answer | Ubuntu-Cloud mailing list at http://goo.gl/fpm0F | News, Venus and Involvement at Cloud Portal http://cloud.ubuntu.com/ | Check EucaBook http://j.mp/h2CEY5 | ||
| koolhead17 | rwat, i would suggest look at the document and see if you have followed it step by step | 11:00 |
| koolhead17 | kim0, cool!! :D | 11:01 |
| rwat | is it only NCs that need bridged networking? | 11:04 |
| rwat | for testing purposes, is it compulsory to have the CC be the IP gateway for all the other servers? | 11:14 |
| kim0 | rwat: that's the supported networking mode .. so pretty much yes | 11:17 |
| rwat | kim0: ok I'll give that a go | 11:23 |
| rwat | in natty what is the purpose of eucalyptus-network ? | 11:24 |
| rwat | in the book it seems to refer to 192.168.20.0/24 in the text but 192.168.10.0/24 in the code examples - are these really two separate networks or a typo? | 11:26 |
| koolhead17 | a typo | 11:27 |
| rwat | also confusing: a local network with the CC as a gateway would seem to imply some kind of NAT setup, but there's no iptables config mentioned in the book | 11:36 |
| rwat | ok I think my networking is now compliant with my interpretation of the manual, but I've still got a bunch of issues | 12:32 |
| rwat | all the commands seem to work | 12:32 |
| rwat | I successfully uploaded a kernel bundle | 12:32 |
| rwat | (this was for the standard fedora image) | 12:33 |
| rwat | I can see it if I ask euca-describe-images | 12:33 |
| rwat | uploaded ramdisk but didn't return id and isn't visible via euca2ools | 12:34 |
| rwat | can't connect hybridfox - it just gives me a blank error | 12:34 |
| rwat | can't run an image from the store "Bad request signature" | 12:35 |
| rwat | wondering if thesee are related and ring any bells with people | 12:35 |

| koolhead17 | kim0, seems like i have to spend nyt in office for the cloud day | 14:09 |
| koolhead17 | kirkland, hey | 14:09 |
| kirkland | koolhead17: hi | 14:09 |
| kim0 | koolhead17: can't you make it from home ? | 14:37 |
| koolhead17 | kim0, no internet yet. just shifted to new place!! | 14:37 |
| kim0 | ah | 14:38 |
| kim0 | I hope it's gonna be enough fun to offset the pain :) | 14:38 |
| koolhead17 | pain is worthy enough to be taken | 14:46 |
| koolhead17 | :d | 14:46 |
