ashtrayI've been here for like 24 hours and no one has said a damn thing04:30
Makere:D06:44
Makereit was weekend06:44
Makerenobody's working with a cloud on weekends duh06:44
Makere;P06:44
ashtray?06:45
ashtraymonday is over06:45
flaccidits tuesday night here06:45
Makereah yes06:47
Makereit's tuesday06:47
Makeremy bad06:48
ashtraylol06:48
Makereplus someone had said in the 24hrs something06:49
Makereanyways, how do I associate ip-address to nodes, they seem to have lost their public ip's overnight and the associate command gives permission denied while trying to release address06:49
sometuxWould someone explain how the computer resources are assigned to each server in the cloud, for example If there's been required two Xeon CPUs how they are virtually assigned? what's the technology used? Is it supposed to be two actual Xeon CPUs to meet the requirement?06:54
TeTeTanyone knows where to get the tinylinux image for UEC from?07:37
MakereI hate my life08:06
MakereTeTeT: it should be rather easy to make it yourself08:09
TeTeTMakere: really? never done so08:09
Makereyes08:09
Makerelemme find a link to howto08:10

Makerethere08:11
Makereanyways, why doesn't my cloud work after being turned off08:12
TeTeTMakere: thanks. I forgot that I could simply loopback mount the official image and inject anything08:17
TeTeTMakere: well, if  it's turned off it should not be running?08:17
Makerewell after starting it ofcourse :)08:20
TeTeTMakere: hmm, does euca-describe-availability-zones give any output?08:23
Makereyea08:23
Makeregot running now08:24
Makerewhat can I do to preserve instances?08:24
Makereto survive shutdown08:24
TeTeTMakere: just restart eucalyptus without CLEAN=108:25
TeTeTMakere: they should be still there, but not sure about the survivability of the network08:25
Makerebut if I shutdown the machines completely08:28
Makerealthough now couple had survived08:28
Makerebut they didn't have public ip08:29
TeTeTMakere: yeah, the public ip is assigned via NAT on the CC, if you reboot it, it will loose it's memory08:29
TeTeTMakere: in summary, the front-end (CC+CLC) is really the brain of your cloud. If it goes down/reboots, so will your cloud08:30
Makereso will I lose my virtual machines by shutting down controllers?08:31
Makereor are they preserved?08:31
Makereshould I shutdown CC or CLC first?08:31
TeTeTMakere: you should first stop all instances, then reboot the front-end. I think CC first, then CLC08:33
Makerehow do I stop the instances without terminating them?08:34
Makerejust shutdown -h now?08:34
Makereor is there some distributed way of doing that?08:35
=== whaley is now known as SirLoins
TeTeTMakere: yes, shutdown -h from inside the instance should do the trick08:35
Makerehow do I start them afterwards then?08:37
flaccidisn't that a terminate?08:37
Makerewell how does eucalyptus recover from power outage08:38
* nigelb joins kim0's world :p08:39
TeTeTMakere: you need to restart the cloud and the apps running on top of it08:41
MakereI did shutdown -h now08:49
Makereit doesn't start anymore08:49
Makerenow it expired08:51
Makereok tried to shutdown CC's and then CLC08:57
Makereand restart08:57
MakereVM didn't get proper public IP08:58
Makereand won't allow me to associate ip to it08:58
=== dendro-afk is now known as dendrobates
=== SirLoins is now known as whaley
jmgallowayanyone here?16:17
nigelbno16:23
jmgallowayis it ok to change the permissions on the /var/lib/eucalyptus/keys directory?16:46
vadi2Hi. Where does one get started with the EC2 and their free offer & Ubuntu from scratch? I found this: http://ubuntu-smoser.blogspot.com/2010/11/using-ubunt-images-on-aws-free-tier.html which assumes that ec2-api-tools is up and running. I downloaded it, but it comes with no visible instructions.17:27

Makereis it possible to take a snapshot from virtual machine state in eucalyptus?20:37
Makereor do I need to create a script that mounts a volume, tars everything up and puts in there?20:41
=== dendro-afk is now known as dendrobates
smoserMakere, the answer is most likely 'no'21:06
smosereuca-bundle-vol is what you would use to basically copy '/' into a new "bundle" that could then be passed to euca-upload-bundle and euca-register-image.21:06
Makereok21:06
smoserbut there is nothing that would give you that below the VM21:06
Makerethank you21:07
smoserand, in reality, you'd want to shut the vm down anyway just to make sure you had a clean filesystem21:07
Makerebut when I shutdown the whole cluster (all controller machines), instances either dissappear or lose their public ip21:08
Makereoh lol, I googled something and noticed that I ended up on smosers blog21:09
MakereI guess I need to start tomorrow by creating some sort of backup plan21:10
smoserwell, the whole idea is that you should be not be putting state in the instances themselves21:10
smoserbut putting any important data on an ebs volume21:10
smoseri realize that isn't 100% realistic21:10
smoserand is really why EC2 backed off that and started offering EBS root21:11
smoser(ebs root instances will be available in 11.04 UEC, per eucalyptus)21:11
Makere....21:11
Makerewell nice to know :)21:11
jmgallowayanyone know how to use hsql at the command line?21:11
smoserbut the idea of "the cloud" is that your intsances are ephemeral21:11
smoserand you should design for their failure above them21:11
smoseranyway... but backing up, what you'll get in /var/lib/eucalyptus... instance-id... is a disk image, not a partition image.21:12
jmgallowayseems that eucalyptus uses hsql to store data, I was wondering how to get access by command line to hsql21:12
smoserit will be a full backup, but if you ever had to create a new AMI based on it, you'd have to get the partition image out of the disk image.21:12
Makerehrr21:14
MakereI starting to lose the point of having a cloud in the first place21:14
Makerejust too many negative things21:14
Makereso there is no way to put root on ebs volume before 11.04?21:15
Makereah well, good night21:18
vadi2How come ec2-run-instances isn't detecting the mykey file? http://paste.pocoo.org/show/295273/23:29
ashtrayIt doesn't look like mykey is in your clouds folder23:33
ashtrayis it in the same folder you are running the command from?23:34
vadi2Yeah...23:34
vadi2$ ls cert-JCQRPACIXXAID2UHNV3RODMYAXFC6W7T.pem  mykey  pk-JCQRPACIXXAID2UHNV3RODMYAXFC6W7T.pem23:35
vadi2vadi@vadi-laptop:~/Documents/Cloud Computing$ ec2-run-instances --region us-east-1 --instance-type t1.micro --key mykey ami-548c783d Client.InvalidKeyPair.NotFound: The key pair 'mykey' does not exist23:35
vadi2Erm, do the cert and pk ids matter?23:35
ashtrayidk i've never connected to an instance like that23:36
vadi2Just pasted them by accident here - should I redo them now? heh23:36
vadi2Trying to follow http://ubuntu-smoser.blogspot.com/2010/11/using-ubunt-images-on-aws-free-tier.html instructions here for the 10gb root image23:37
ashtraysorry I'm the wrong person to ask.  I haven't created an instance from the command line23:37
ashtrayI create from AWS interface23:37
ashtrayjust thought i would try to help since no one else answered23:37
vadi2alrighty23:38
vadi2did you make yours be 10gb ubuntu?23:38
ashtrayya23:38
vadi2oh well, I'll try that then23:38
vadi2followed any guide or just clicked about?23:38
ashtrayoh ur on the free tier/23:38
ashtray?23:38
vadi2yeah23:39
ashtrayi was looking at that article last night23:39
ashtraydidn't try it out though23:39
vadi2alright23:39
