Re: [one-users] Tiny Local Business scenario for openNebula
Hi, OpenNebula can be used for the scenario you describe, even if you are not going to take advantage of its on-demand cloud features. It will provide a centralized view and management of your Images and VMs, what will surely help to administer and monitor your virtualized workstations. OpenNebula can use the same computer as the front-end and host, the only thing to keep in mind is that you need to use the shared storage transfer manager [1] (the front-end and the hosts are sharing the same storage). Knowing that all the VMs will be windows, you may want to configure remote desktop access to the guest OS instead of VNC. Regards.

I appreciate your answer. I was expecting to be able to install kvm, sshd, and openNebula on the same hardware. As I would not need to provide many different technologies. I think that I would have maybe 4 VM at the same time, but the virtual processor will be most of the time sleeping. Will this be in some software related conflict ? Or your recommendation is due to the load ? It sounds that the method you describe, involves the same procedures as installing openNebula. Kind regards, Diego 2011/10/26 Ben Tullis b...@tiger-computing.co.uk: Hi Diego, I don't think that OpenNebula is likely to be the best tool for the job in this case, as it is more geared towards on-demand cloud computing. However, it does sound like you could really benefit from virtualization in the office. The way I would approach your situation is as follows. Make sure that the machine you're going to use as a server has hardware virtualization support built in. http://en.wikipedia.org/wiki/Intel_VT#Processor Use disks in pairs of equal sizes, then install Linux and configure software RAID1 so that the system will be able to withstand a failure in any disk. http://en.wikipedia.org/wiki/Mdadm Install a hypervisor to enable you to run many concurrent virtual machines. You might like to consider KVM, Xen and Virtualbox. http://www.linux-kvm.org http://wiki.xensource.com/xenwiki/ http://virtualbox.org You can then define virtual machines and install Windows onto them, in order to make them available to your colleagues. You can use normal Windows system management techniques (such as sysprep) to deploy pre-configured Windows system images, thereby saving you time. You could then use VNC to make these virtual machines available to your staff, in the manner that you suggest. I'm currently looking at building an OpenNebula cluster to support a small-business requirement, but I can't really see that there is any way of ensuring high-availability in any system with fewer than four physical servers in it. I think you'd be making things unnecessarily hard for yourself if you tried to do it all on one server. I hope that helps.
