Snippet from Wikipedia: OpenNebula

OpenNebula is an open source cloud computing platform for managing heterogeneous data center, public cloud and edge computing infrastructure resources. OpenNebula manages on-premises and remote virtual infrastructure to build private, public, or hybrid implementations of Infrastructure as a Service and multi-tenant Kubernetes deployments. The two primary uses of the OpenNebula platform are data center virtualization and cloud deployments based on the KVM hypervisor, LXD/LXC system containers, and AWS Firecracker microVMs. The platform is also capable of offering the cloud infrastructure necessary to operate a cloud on top of existing VMware infrastructure. In early June 2020, OpenNebula announced the release of a new Enterprise Edition for corporate users, along with a Community Edition. OpenNebula CE is free and open-source software, released under the Apache License version 2. OpenNebula CE comes with free access to patch releases containing critical bug fixes but with no access to the regular EE maintenance releases. Upgrades to the latest minor/major version is only available for CE users with non-commercial deployments or with significant open source contributions to the OpenNebula Community. OpenNebula EE is distributed under a closed-source license and requires a commercial Subscription.

AlmaLinux/RHEL¶ To add OpenNebula repository, execute the following as user root:

RHEL 8, 9

# cat << "EOT" > /etc/yum.repos.d/opennebula.repo
[opennebula]
name=OpenNebula Community Edition
baseurl=https://downloads.opennebula.io/repo/6.8/RedHat/$releasever/$basearch
enabled=1
gpgkey=https://downloads.opennebula.io/repo/repo2.key
gpgcheck=1
repo_gpgcheck=1
EOT
# yum makecache

# cat << "EOT" > /etc/yum.repos.d/opennebula.repo
[opennebula]
name=OpenNebula Community Edition
baseurl=https://downloads.opennebula.io/repo/6.8/AlmaLinux/$releasever/$basearch

# yum makecache

If the commands below fail, ensure you have gnupg, wget and apt-transport-https packages installed and retry. E.g.,

apt-get update apt-get -y install gnupg wget apt-transport-https First, add the repository signing GPG key on the Front-end by executing as user root:

wget -q -O- https://downloads.opennebula.io/repo/repo2.key | gpg –dearmor –yes –output /etc/apt/keyrings/opennebula.gpg Debian 10

# echo "deb [signed-by=/etc/apt/keyrings/opennebula.gpg] https://downloads.opennebula.io/repo/6.8/Debian/10 stable opennebula" > /etc/apt/sources.list.d/opennebula.list
# apt-get update
