[08:06] <areay> hi all.. i'm using UEC -- is it possible to have more than one VM per cpu core? i understand this is the default but is there a way to override it?
[08:08] <kim0> areay: Hi .. are you saying if your NC has 2 cores .. you can only launch two VMs ?
[08:09] <TeTeT> areay, kim0 : there's a MAX_CORE or MAX_CORES setting for the nc that overrides the default
[08:10] <areay> kim0 -- i haven't actually gotten that far yet lol.. but the ubuntu server guide says that "by default, Eucalyptus will only run 1 VM per CPU core on a Node."
[08:10] <areay> TeTeT, how do i configure that setting?
[08:11] <TeTeT> areay: I have the following entry:
[08:11] <TeTeT> /etc/eucalyptus/eucalyptus.conf:MAX_CORES="32"
[08:12] <TeTeT> on the node controller. So this node can host up to 32 vm's, which is a bit high, but it's only for training and testing
[08:12] <areay> thanks bro :) sorry i'm new at this -- that should have been the first place i looked
[08:13] <areay> TeTeT, how do i reload the settings after i edit the file? i better ask or i'll end up rebooting like a noob lol
[08:13] <TeTeT> areay: sudo restart eucalyptus-nc or sudo restart eucalyptus-nc CLEAN=1
[08:13] <areay> tyvm!
[08:13] <TeTeT> areay: be aware that you loose any already running instances on that node
[08:14] <areay> np i don't have any yet :) also my node is saying kvm disabled by bios -- is that as big of a problem as it sounds?
[08:15] <kim0> I think so .. visit bios and try enabling any virtulization thing
[08:16] <areay> kk cool i'm on it :) thanks u guys are stars
[08:53] <areay> ok, i've downloaded and installed an image... once i instantiate it, what happens if it, the NC, or the CC reboots? do i need to save snapshots? i'm kinda lost :/
[09:20] <areay> ok ignore above post -- my instance is running... but i cannot ping or connect via ssh. i instantiated using hybridfox, and when i choose "connect" it's asking me for a private key file? where do i find this key?
[09:24] <areay> ok i'm getting further -- i get output from ssh now but i need that key :/
[09:34] <areay> <-- stupid. i didn't create a keypair before i instantiated... disregard above question ;)
[11:25] <TeTeT> areay: good luck with your discovery of uec :)
[11:47] <areay> haha thanks tetet :)
[14:19] <superxgl> echo -at $logdir
[14:20] <superxgl> oh,sorry
[14:35] <kim0> :)
[18:01] <areay> Hi all... I have a couple questions about the basics of UEC/cloud computing in general -- firstly, i understand that instances are considered disposable - if i want specialized "appliances" (mysql, vpn, etc) do i need to create custom images in order to be able to swap them out on the fly with minimal configuration?
[18:01] <areay> or do i create a "snapshot"?
[18:03] <areay> also, i understand that sensitive data should be kept on a "volume" -- are these volumes held on the nc or on the clc/cc/sc/walrus box?
[18:06] <areay> if anyone can answer even one of these questions i'd be extremely appreciative :)
[18:34] <kim0> areay: yes instances are disposable, yes important data should be on a volume .. which is stored on SC
[18:34] <kim0> areay: for appliances .. I would boot a generic image then customize it using something like cloud-init and/or puppet
[18:36] <areay> kim0, so customize it as a running instance? or chroot into the image? --also once the image is done what's the best way to save it?
[18:36] <kim0> areay: It's not like that .. the "modify instance, then make an image out of it"
[18:37] <kim0> is a valid approach .. but not the solution  I'd recommend .. instead
[18:37] <kim0> I'd boot generinc image, it picks up customization instructions from cloud-init and/or puppet, it becomes "mysql-appliance", then mounts ebs volume which your data, now it's your-appliance
[18:38] <kim0> no snapshotting needed
[18:38] <kim0> everything can be rebuilt in seconds
[18:40] <areay> kim0, sounds good -- which is better, cloud-init or puppet?
[18:41] <kim0> areay: ehum .. consider them complementary :)
[18:41] <kim0> cloud-init is for initial bootstrapping .. you can stop there .. or you can continue with puppet
[18:41] <kim0> read more about both .. and see what you want to use
[18:42] <areay> sorry for the noobish questions -- i'm VERY new to all this and the documentation available is sparse at best.. i was using multi-roled servers before.. is there like a guide or anything? a simple guide to setup a lamp appliance or something would be ideal so i can see all this in practice...
[18:43] <kim0> areay: check out my cloud-init stuff at http://foss-boss.blogspot.com/search/label/cloud-init
[18:43] <areay> awesome :) tyvm kim0
[18:43] <kim0> areay: read bottom to top :) has wordpress example (LAMP stack) and all
[18:44] <areay> kim0, nice blog btw -- i take it that's yours :)
[18:45] <kim0> yep :)
[18:45]  * kim0 afk for now
