NASA was using Eucalyptus before and as far as I know Nova is a complete rewrite from scratch. Comparing the designs it seems that one distinguishing factor is that OpenNebula has a central cloud controller which is a potential single point of failure and potentially a bottleneck when scaling the size of the cloud (don't know if this is an issue in practice). Nova design seems to be more loosely coupled (but I might be wrong on this, as information on the web about Nova at this stage does not seem always easy to understand or be consistent with other information you find). > I like, that OpenNebula doesn't want to impose certain constraints on the > users regarding his or her infrastructure.

It is interesting that I am still using REXML on my scripts but Opennebula automatically uses nokorigi to take care its own XML handling which is now doing the proper output (and it looks better too). But still, I think OpenNebula should work with both REXML and Nokogiri and there might be some work needed for the REXML to output the proper format. Thanks.

[one-users] Open Nebula and Scheduling
Hi, All, I'm researching the possibility of using Open Nebula as a tool to build a cloud for HPC purposes. What I'd like to do is use existing HPC infrastructure to run virtual machine instances and VM-based clusters for specific applications, the goal being to reduce lead time for application deployment and to support applications that have very specific platform requirements that don't necessarily mesh well with our existing HPC setup. What I'd like to do is continue to schedule jobs against the existing HPC environment using a traditional batch scheduler like Torque/Maui and use something like Open Nebula to request, from the batch scheduler, advance reservations for resources to run VMs. Obviously, the needed infrastructure is already in place (multi-core cluster nodes with gobs of memory, network, etc.). My main interest is in whether or not either a) Open Nebula can interface with a third-party scheduler to schedule the standing-up of VM instances or b) It would be possible to extend open nebula to interface with a third-party scheduler and which bits of the code base I should be interested in for this. The goal, from the end-user's perspective, is to be able to continue to schedule and run traditional bare-metal HPC jobs through Torque/Maui while at the same time, new users who have specific application needs can say "I need X cpus, Y RAM, and Z nodes to run my application for the next month" and have Torque/Maui handle the reservation or the resources while Open Nebula takes care of the rest. Any pointers or advice would be greatly appreciated!

Readers would have to detect whether it is a trolling attempt or not. I cannot fathom, how many productive installations of OpenStack exist today. That's why it might be very difficult to find people or organisations that switched from OpenStack to OpenNebula. At the same time, I'm interested in OpenStacks general architecture (which I found after a few clicks under http://nova.openstack.org/nova.concepts.html). What I like about Nova is, that it support UML from the beginning. That's something I'd like to see in OpenNebula as well (or OpenVZ or LXC for that matter). Furthermore, as an OpenNebula user I'm interested in Swift and whether it can be integrated into OpenNebula as storage for VMs. At the moment there seems to be no reason to change from OpenNebula to OpenStack. And the only reason why Nasa and Rackspace have not considered OpenNebula as their new platform might be the effort that already went into the various components from which OpenStack was "composed". I like, that OpenNebula doesn't want to impose certain constraints on the users regarding his or her infrastructure. It integrates itself very well into existing setups. As a good toolkit should do.

Yeah, same here :| ...
OpenNebula can produce the XML output both using the Nokogiri gem or
REXML if Nokogiri is not found. I'm using Nokogiri with the last git
version and all CDATA content I can see is on the same line as the
enclosing labels.
Perhaps it is the case that you are not using nokogiri? If so, you can
consider trying again after installing it.

Re: [one-users] putting OS images in the image repository
Hi Steven, This is an interesting use-case. When we designed the image repository, we had to make a compromise between "expectable behaviour" and "advanced customization usage". I guess this falls into the advanced usage, but OpenNebula is flexible enough to take this challenge. To automatically save all VM disks that use a certain Image, you can use hooks. I would add a new flag to all the relevant images in your system, either having them in the image template, or adding them afterwards [1]: oneimage addattr AUTO_SAVE YES This will add the flag to the template: $ oneimage show 1 IMAGE INFORMATION [...] IMAGE TEMPLATE *AUTO_SAVE=YES* DEV_PREFIX=hd NAME=test_image PATH=/home/cmartin/trabajo/scratch/steven/disk.img TYPE=OS To add a new hook to the system, edit $ONE_LOCATION/etc/oned.conf [2] and add something similar to the following: VM_HOOK = [ name = "auto_save", on= "CREATE", command = "auto_save.rb", arguments = "$VMID" ] This will execute a new script, placed in $ONE_LOCATION/share/hooks/auto_save.rb, every time a new VM is created. I suggest you to use ruby, because the ruby OCA API [3] will make it easier. This script will have to: 1) Get the complete information for VM from OpenNebula. 2) For each disk, check if it is using an Image. 2.1) Get that image's information, and look for the AUTO_SAVE=YES attribute. If it's present, then issue a onevm saveas operation over that and . To be able to identify the disks later, you could include in the new image name the _ string. This way, files will be all managed by OpenNebula in the repository. If you are doing this for back-up purposes, and you won't actually instantiate a VM using this saved images, you can always move that files away from the repository and then delete the images. This is the easiest and "elegant" way I see to do this, but any other opinions are welcome. I'd also like to ask the community if more people feel this should be supported out of the box by OpenNebula. If so, we could start a discussion to determine the specific features or requirements this would imply. Best regards, Carlos.

Re: [one-users] OpenNebula vs OpenStack
Nova (the part of OpenStack that compares with OpenNebula) is *very* immature at the moment. It's a brand-spanking new project only a few months old, and doesn't really do much at the moment. In the long run, it may compare favorably with OpenNebula, but it will be at least 6 months before Nova begins to catch up. I know a couple of people working on Nova, and they're VERY good developers, so I have no doubt it will be a very nice piece of software in the future. If you want to put it into production today... don't. It's pre-alpha and not even close to feature-complete. You can launch VMs from Nova, but not much more than that. There's currently not any solid multi-user support, for example. It's worth tinkering with, for sure, but not for production. OpenNebula is mature, proven, and works pretty well. It's not as slick as some of the commercial products available, but it's much more hackable (seriously - I've said it before and it's still true - there is NO virtual infrastructure manager more hackable than OpenNebula), and the community ecosystem is complex and useful. From the ecosystem you can install a graphical interface, alternate schedulers, and many install automation tools. If you want to look at more mature software to compare, Cloudstack (very slick, use their reference architecture until you understand how the pieces fall together), Eucalyptus (good luck! Ubuntu Enterprise Cloud is still the only reliable, simple way to get this going), Ganeti (very interesting, DRBD backing store, not intended for large scale though) are good comparison examples to test.

Re: [one-users] OpenNebula vs OpenStack
Dear Christophe, We prepared a post [1] with a description of our position as open-source project when OpenStack was announced in July. From a more technical point of view, OpenNebula is a mature technology (we started the development five years ago and did our first release almost three years ago) that is used to manage very large scale clouds by some of the world's leading telecom operators, hosting providers and compute centers of leading research institutions. In our web site [2] we provide details about the features for private, public and hybrid cloud management, integration and production environments. We invite you to compare these features with those provided by OpenStack and evaluate which technology fits your requirements.
