What I am trying to achieve is what I already do with other KVM-based virtualization platforms: allocating to every VM much more cpu than actually available on the host (ex: 16 VMs with VCPU = 4 and CPU = 1), so a single VM can get a lot of cpu power when needed. In the case there are many VM using a lot of cpu, it will be equally shared among them by the Linux process scheduler on the host. Am I missing something? Is this a bad practice?

[one-users] fencing a failed host?
Hi, the host hook documentation page says: Additionally, there is a corner case that in critical production environments should be taken into account. OpenNebula also has become tolerant to network errors (up to a limit). This means that a spurious network error won't trigger the hook. But if this network error stretches in time, the hook may be triggered and the VMs resubmitted. When (and if) the network comes back, there will be a potential clash between the old and the reincarnated VMs. In order to prevent this, a script can be placed in the cron of every host, that will detect the network error and shutdown the host completely (or delete the VMs). There is a suggested implementation for this kind of script? Someone is already using it in production?

Re: [one-users] Installation of OpenNebula 3.2 on Ubuntu OS
Hi Poul, 2012/1/31 Poul Kristensen bcc5...@gmail.com: Would someone suggest the easiest way to install OpenNebula 3.2 to Ubuntu? It's easy, you just need to read the documentation. If you mean the fastest method, you may want to use pre-built .DEB packages. Should OS be Ubuntu server version 10.04(with the included packages or are the packages to old?) or Ubuntu server version 11.10? Ubuntu 10.04 is pretty good for ON, you may prefer 11.10 only for having a more recent KVM version, but you may wish to stick to an LTS edition in production. Should it be compiled and if so how can I be sure that all packages are installed needed to get a succesfull compilation in first try? IMHO the self-contained install from sources is the best option since all the ON files will be on a separated system folder (eventually on a shared resource among hosts), very handy when upgrading or backup purposes.

Re: [one-users] Distributed File System with OpenNebula
Hi Alexandre, 2012/3/22 Alexandre Fouchs alexandrefou...@gmail.com: My concern is now how does it really work ? For example if I have 2 hypervisors or more, would it be possible to access the same share space with something else than NFS ? And would it be seen as one unique system from a user point of view (with loadbalancing I assume) ? We would prefer not to use NFS but I haven't seen alternatives yet. If you stick with ESXi, yes, you don't have many other choices. Instead, with KVM and Xen, you can use every supported storage technology usually available with a standard Linux system. Apparently DFS such as MooseFS exist but what I would like is to be able to connect Unix VM to it but also Windows VM, and MooseFS is Unix only from what I undestand. You are missing that DFS are usually used as backend storage, so their support is strictly depending on your hypervisor hosts and not on the VM instances. In other words, you can use MooseFS to run both Linux and Windows instances, but you need to use KVM/XEN hosts and not ESXi. -- Giovanni Toraldo http://gionn.net/about-me http://it.linkedin.com/in/giovannitoraldo ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

[one-users] Chef cookbook for OpenNebula (to be used with Vagrant)
Hi! Recently I was interested in using Vagrant plus some Chef recipes to easily bootstrap a development machine containing OpenNebula. I've published a very basic cookbook that will install build dependencies and opennebula from sources, served by Vagrant (tested under Ubuntu 12.04) The GitHub repository of the cookbook: https://github.com/gionn/chef-opennebula If you want to take a look to my Vagrantfile, it's here (along with the latest OpenNebula sources): https://github.com/liberologico/one/blob/vagrant/Vagrantfile If someone is interested in expanding this cookbook, pull requests are warmly welcomed (even for fixing crap I put into it) Cheers, -- Giovanni Toraldo http://gionn.net ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
[one-users] Trying jclouds to manage OpenNebula
Hi, just to share a few discoveries of the last few days. I've tried to manage OpenNebula instances with jclouds [1]. It doesn't comes with a native OpenNebula driver, however it contains a generic EC2 driver, that could be used along with the OpenNebula econe-server. Hence some rough edges [2] [3], I've achieved to succesfully authenticate, and retrieve the list of available images and active instances. Unfortunately, to be able to instantiate new VMs with jclouds, it looks like that the CreateSecurityGroup method should be implemented in econe-server (since jclouds relies on it to manage instances grouping, even when launching a single instance). Is that feasible with the current OpenNebula, without a way to logically group instances together? Maybe injecting a custom variable in the templates? Any suggestion is highly appreciated, thanks!

And other question I have after browsing the files, how does it download the code? I could not figure out how the source code reaches the vagrant machine. this is how Vagrant actually works: it launches a virtual machine and expose the current working directory into the virtual machine using a shared folder (http://docs.vagrantup.com/v2/getting-started/synced_folders.html). It's nice to have OpenNebula running inside a VM with all dependencies automatically installed in a few minutes, and you can easily modify OpenNebula source code from your IDE running on your host machine. I hope to be able to expand the chef recipes to cover also the OpenNebula installation via binary packages and to automate the opennebula configuration.
