oVirt adalah perangkat lunak virtualisasi sumber terbuka dan gratis yang digunakan di Linux seperti sistem operasi seperti Fedora, CentOS, dan RHEL. Dengan kata lain kita dapat mengatakan oVirt adalah alternatif dari VMware vSphere di Linux. Komunitas Ovirt didirikan dan didukung oleh Red Hat dan dianggap sebagai proyek upstream untuk Red Hat Enterprise Virtualization (RHEV ).
oVirt terdiri dari dua komponen utama :
- Mesin oVirt
- Node Virt
Mesin oVirt adalah antarmuka pengguna grafis atau kita dapat mengatakan itu adalah portal administrator Web tempat kita dapat mengelola mesin virtual, komputasi, jaringan, dan sumber daya penyimpanan.
simpul oVirt adalah Server RHEL / CentOS atau Fedora tempat layanan vdsm aktif dan berjalan. Node Ovirt akan bertindak sebagai Hypervisor (KVM) di mana semua mesin Virtual akan dibuat.
Pada artikel ini kita akan menginstal versi terbaru oVirt 4.0.3 pada CentOS 7 / RHEL 7 . Kami akan menggunakan dua server satu akan bertindak sebagai mesin ovirt dan lainnya akan bertindak sebagai node ovirt. Berikut detailnya :
oVirt Engine :ovirtengine.example.com (192.168.1.30 )
oVirt Node :ovirtnode.example.com (192.168.1.40)
Perbarui entri di bawah di file /etc/hosts jika Anda tidak memiliki server dns lokal.
192.168.1.30 ovirtengine.example.com 192.168.1.40 ovirtnode.example.com
Langkah-Langkah Instalasi oVirt Engine pada CentOS 7 / RHEL 7
Berikut adalah persyaratan minimal untuk ovirt-engine :
- OS Minimal ( CentOS 7.x / RHEL 7.x )
- Server inti ganda
- RAM 4 GB
- Ruang Disk 25 GB
- Kartu Lan 1-Gbps
Lakukan langkah-langkah berikut satu demi satu untuk menginstal mesin ovirt.
Langkah:1 Perbarui server menggunakan perintah yum
Instal pembaruan terbaru di server menggunakan perintah di bawah yum.
[[email protected] ~]# yum update -y
Setelah pembaruan diinstal, reboot server.
Langkah:2 Aktifkan Repositori oVirt 4.0.3
paket mesin ovirt tidak tersedia di repositori CentOS dan RHEL yum. Jalankan perintah di bawah ini untuk mengatur dan mengaktifkan perbendaharaan ovirt 4.0
[[email protected] ~]# yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release40.rpm
Langkah:3 Instal Paket Mesin oVirt menggunakan perintah yum
Jalankan perintah yum berikut untuk menginstal mesin ovirt.
[[email protected] ~]# yum install ovirt-engine -y
Langkah:4 Mulai penginstal mesin ovirt
Jalankan perintah ‘engine-setu p' dari konsol, itu akan memulai penginstal mesin ovirt dan secara interaktif akan mengajukan serangkaian pertanyaan selama instalasi dan akan menyimpan semua jawaban ke file jawaban. File jawaban dapat digunakan kembali untuk mengotomatiskan penginstalan.

Jika firewall diaktifkan di server Anda , lalu jalankan langkah-langkah yang disebutkan dalam output di atas.
Langkah:5 Akses portal Administrator Web oVirt Engine.
Buka browser web dan ketik URL :
https://ovirtengine.example.com
atau
https://IP_Address
Ganti nama domain atau alamat IP sesuai pengaturan Anda.
Klik Portal Administrator.
Masukkan nama pengguna sebagai ‘admin ' dan kata sandi yang kami sebutkan selama instalasi dan Profil sebagai internal.
Pada titik ini instalasi mesin ovirt selesai, sekarang instal node ovirt.
Langkah-Langkah Instalasi oVirt Node (Hypervisor)
oVirt Node dapat dikonfigurasi dalam dua metode yang berbeda , Metode pertama adalah kita dapat mengunduh hypervisor atau ovirt-node iso file dari situs web resminya dan instal server dari file iso yang diunduh.
Metode kedua adalah kita dapat membuat CentOS yang sudah ada , RHEL dan Fedora server sebagai node ovirt dengan menginstal paket vdsm di atasnya dan kemudian kita akan menambahkan host atau server tersebut secara manual dari portal administrator mesin ovirt.
Persyaratan minimum untuk oVirt Node adalah :
- Sistem Inti Ganda
- RAM Fisik 10 GB
- Ruang Disk 10 GB
- Kartu Lan 1-Gbps
Dalam tutorial ini saya akan menggunakan metode pertama, saya sudah mengunduh oVirt 4.0 Node iso mengajukan. Bakar file iso yang diunduh ke dalam DVD atau drive USB dan Boot server boot dengan DVD/USB ikuti petunjuk Layar.
Pilih opsi pertama ‘Install oVirt Node 4.0.3 ‘
Pilih Bahasa dan Klik Lanjutkan …
Pada Langkah Selanjutnya lakukan langkah-langkah berikut :
- Konfigurasikan Jaringan
- Tetapkan Nama Inang
- Pilih disk untuk penginstalan OS
- Tanggal dan Waktu sesuai penyiapan
- Tata Letak Keyboard
Dalam Kasus saya, Hostname adalah “ovirtnode.example.com ” dan alamat IP adalah 192.168.1.40
Klik Mulai Instalasi
Setel kata sandi root dan klik selesai
oVirt 4.0.3 Instalasi node sedang berlangsung.
Setelah penginstalan selesai, reboot server Anda.
Tambahkan ovirt Node (ovirtnode.example) di mesin ovirt dari Portal Administrator Web.
Masuk ke Portal Administrator , Buka Tab Host —> klik Baru
Tentukan detail node ovirt.
Setelah selesai dengan entri, klik OK.
Saat saya melakukan penyiapan ini di lab saya, saya tidak akan "Mengonfigurasi Manajemen Daya “. Klik Oke
Seperti yang dapat kita lihat di bawah bahwa mesin ovirt sedang menginstal perangkat lunak pada node ovirt. Jika host tidak diaktifkan setelah menginstal perangkat lunak, lalu pilih Host dan Klik Aktifkan
Seperti yang kita lihat, Host sudah diaktifkan sekarang.
Itu saja. Semoga Anda menyukai langkah-langkah instalasi dan Konfigurasi oVirt 4.0.3. Pada artikel mendatang kita akan membahas cara membuat pusat data, cluster, dan mesin Virtual.
