entendendo a topologia

instalação do front-end

apt-get -y install gnupg wget apt-transport-https
wget -q -O- https://downloads.opennebula.io/repo/repo2.key | apt-key add -
echo "deb https://downloads.opennebula.io/repo/6.6/Debian/11 stable opennebula" > /etc/apt/sources.list.d/opennebula.list
apt update
apt-get -y install opennebula opennebula-sunstone opennebula-fireedge opennebula-gate opennebula-flow opennebula-provision
apt-get install mariadb-server

    PASSWD = "password",
    DB_NAME = "opennebula",
    CONNECTIONS = 25,
    COMPARE_BINARY = "no" ]

iniciar e ativar serviços

 systemctl start opennebula opennebula-sunstone opennebula-fireedge opennebula-gate opennebula-flow
 systemctl enable opennebula opennebula-sunstone opennebula-fireedge opennebula-gate opennebula-flow

verificar e configurar senha oneadmin

oneuser show
passwd oneadmin

instalação do node de virtualização

 apt update
 apt-get -y install opennebula-node-kvm
 systemctl restart libvirtd
 passwd oneadmin
