Hi, I’m very new to opennebula or any private cloud solutions. we have some 4 servers where we wanted to try opennebula. All of them are in same network. they are big servers and wanted to explore easy vm creation n management.
Need some guidance in setting up the opennebula on them and creating the VMs on them. VMs should be discoverable from any of the hosts. If we are able to bring up instances, we want try them adding to k8s also in long term. Any help with respect to documentation, setup help, best practices and things we should consider for this uses or similar architecture is much appreciated.

Hi @BalaS! Welcome to the OpenNebula Forum :smile:

Here are some general guides to get you started:

Setting Up OpenNebula

You’ll need to install OpenNebula on one of your servers, which will act as the Front-end, while the other three will be Hypervisors (hosts). The official installation guide is here:

For your use case, I’d also recommend using KVM as the hypervisor:

Adding Hosts & Creating VMs

Once the installation is complete, you need to add the remaining servers as hosts in OpenNebula. I’d recommend you to take a look at this section of the documentation where all the details related to Host and Cluster management are discussed:

A similar guide is available for Virtual Machines management:

Finally, regarding Networks, before configuring anything, I recommend checking out this guide on how Virtual Networks work in OpenNebula. Once you’ve read it, you should have a better idea of which Network driver to use:

Other resources

In addition to the official documentation, we also provide a variety of screencasts and online tutorials on our YouTube channel, where we frequently upload new content, including step-by-step guides, demonstrations, and deep dives into new OpenNebula features.

Here are some useful videos to get started:

You can explore more videos and subscribe for future updates in the official OpenNebula’s Youtube channel. :rocket:

I hope this helps you get started with OpenNebula! Feel free to ask if you have any questions along the way. :blush:

Cheers,
Victor.

Hey @vpalma,
Thanks for sharing all the resources and guides. I was just checking the one-deploy playbook. would u recommend using that for the setup. Also having questions regarding single frontend vs HA frontend. Is it possible to recover to original state if the single frontend server crashes or corrupted and what is the effort to recover it.
