Pengaturan manajer tambahan

$ sudo yum install bash-completion vim

Menambahkan Nama DNS Tambahan

$ sudo vim /etc/ovirt-engine/engine.conf.d/99-custom-sso-setup.conf

SSO_ALTERNATE_ENGINE_FQDNS="ovirt.example.com some.alias.example.com ovirt"

$ sudo systemctl restart ovirt-engine

Konfigurasikan otentikasi melalui AD

$ sudo yum install ovirt-engine-extension-aaa-ldap-setup
$ sudo ovirt-engine-extension-aaa-ldap-setup
$ sudo systemctl restart ovirt-engine

Pengaturan pengelolaan daya

• Gabung
• Konsol jarak jauh
• Daya virtual dan reset
• Media virtual
• Konfigurasikan Pengaturan iLO
• Mengelola akun pengguna

Penyiapan SSL

• sertifikat CA penerbit dalam format PEM, dengan seluruh rantai ke CA akar (dari penerbit bawahan di awal ke akar di akhir);
• Sertifikat Apache yang dikeluarkan oleh CA penerbit (juga dilengkapi oleh seluruh rantai sertifikat CA)
• kunci pribadi untuk Apache, tanpa kata sandi.
