HA front-end nodes as VMs deployment fails when libvirt is pre-installed not from opennebula-node-kvm metapackage

[mkutouski]

Description The deployment fails in the scenario when HA front-end nodes need to be deployed as VMs if the Libvirt software is pre-installed using apt install -y libvirt-clients libvirt-daemon-system qemu-kvm but not apt install opennebula-node-kvm in Ubuntu. The reason for such behavior seems to be missing oneadmin user on the node(s) where VMs need to be deployed. Whereas it's written in the docs the following:

The bare metal hosts should have Libvirt software pre-installed (for example apt install -y libvirt-clients libvirt-daemon-system qemu-kvm or apt install opennebula-node-kvm in Ubuntu). This step is left to the user.

So either documentation needs to be fix or the corresponding piece of the one-deploy tool.

To Reproduce Create Ubuntu 22.04 host. Install libvirt software:

apt install -y libvirt-clients libvirt-daemon-system qemu-kvm

Prepare inventory/<env>.yml file following documentation.

Execute

make I=inventory/test.yml infra
...
