Re: [one-users] GRID-like functionalities with OpenNebula as a base? [Hadoop, or other possible solutions]

Hi ! Does your succesfully setup mean that you did not face any problems at all working with all components of OpenNebula including cluster architecture, snapshots rollback without any io errors, sunstone working etc? Concerning gridengine I know that medical companies like Novo Nordisk is

[one-users] external DHCP

Hello, We're building a VM farm with OpenNebula. However, I'm a little bit confused about how to handle networking. Our scenario is based on VLAN tagging and external DHCP server for every VLAN. Our goal is to use that external DHCP server to provide IPs for all VMs. When creating a Virtual

Re: [one-users] storage mount for VMs

Hi, Yes, you are right. Next version of OpenNebula features multiple datastores. In particular, there is a special one (the system datastore) for storing disk images of running VMs (the /var/lib/one/vm_id/images dirs). Among other benefits this allows the use of multiple datastore types (TM if

Re: [one-users] Bridge configuration missing from ovswitch driver?

A misunderstanding on my part. Ovswitch, unlike the Linux Bridge driver, needs only one bridge to function. If for example you have two VMs in the same host, and want them to be in different VLANs (e.g vlan 1 and 2), with Linux bridges you accomplish that with vm nicto

[one-users] New blog post on using EC2-like Elastic IPs and Security Groups with OpenNebula

Hi all, We don't usually announce blog posts on our mailing lists, but we felt this one would be of interest to many of you: http://blog.opennebula.org/?p=2695 In this post, Sebastien Goasguen describes the work his team at Clemson University has done to add support for EC2-like

[one-users] What happens with multiple front-ends?

Hi all, I'm currently evaluating OpenNebula, with the aim to setup a redundant cloud for our research group. My setup will have two physical machines connected with Gigabit Ethernet. I'm planning to use GlusterFS as image storage and MySQL cluster for the database, to obtain complete redundancy.

Re: [one-users] What happens with multiple front-ends?

I think you should not make this that complicated, use a light weight vm to host the open nebula server. The sqlite db works great for small installs and you can easily migrate or restart the vm on the other host if you need to bring a host down. On Mar 21, 2012 1:19 PM, Leonardo Montecchi

[one-users] Passwordless ssh between VM's?

Hello everyone, I'm looking for the most convenient setting to be able to passwordlessly ssh between the VM's created by OpenNebula. I've noticed that the settings which provide passwordless ssh from the Front-end (or Hosts) into VM's do not deal with this, the system is still asking for a
