Ovirt adalah software virtualisasi yang bersifat free dan opensource, yang dapat digunakan dalam linux seperdi fedora, centos dan RHEL dengan kata lain kita dapat mengunakan oVirt sebagai alternatif dari VMware vshpere di linux. Komunitas oVirt didirikan dan didukung oleh Red Hat dan dianggap sebagai proyek hulu untuk Red Hat Enterprise Virtualization (RHEV) => (linuxtechi)
Ovirt Terdiri dari dua komponen utama yaitu :
- oVirt Engine
sebagai portal administrator web dari situ kita dapat megolah virtual machine, komputasi, storage , network dan storage.
- oVirt Node
oVirt Node bertindak sebagai Hypervisor (KVM) di mana semua mesin virtual akan dibuat.
karena oVirt ini berdiri diatas KVM maka kita harus mengecek apakah server yang kita install mendukung hardware acceleration untuk virtual machines, dengan cara seperti ini dan nilainya harus diatas 0 (nol)

[root@controller ~]# egrep -c '(vmx|svm)' /proc/cpuinfo 4 |
Artikel ini kita akan menginstal versi terbaru oVirt 4.0.5 pada CentOS 7 / RHEL 7. Saya akan menggunakan dua server yang akan bertindak sebagai oVirt Engine dan lainnya akan bertindak sebagai oVirt Node. Berikut adalah rincian:
- oVirt Engine: controller (10.0.0.10)
- oVirt Node: compute (10.0.0.20)
edit pada /etc/hosts

10.0.0.10 controller 10.0.0.20 compute |
Langkah instalasi oVirt Engine di CentOS 7 / RHEL 7
Berikut ini adalah persyaratan minimal untuk oVirt-Engine:
- Minimal OS (CentOS 7.x / RHEL 7.x)
- Server dual core
- 4 GB RAM
- 25 GB Disk Space
- 1-Gbps Lan Card
Langkah: 1 Update server menggunakan perintah yum
|
1 |
[root@controller ~]# yum update -y |
Langkah: 2 Aktifkan Repository oVirt 4.0.5
|
1 |
yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release40.rpm |
Langkah: 3 Install Package oVirt Engine menggunakan perintah yum
|
1 |
[root@controller ~]# yum install ovirt-engine -y |
tunggu sampe proses installasi selesai….
Langkah: 4 jalankan installer oVirt Engine
|
1 |
[root@controller ~]# engine-setup |
nanti akan muncul serangkaian peratanyaan secara interaktif , ikuti seperti dibawah ini

Langkah: 5 Akses oVirt Engine Web Administrator Portal.
|
1 |
https://10.0.0.10 |
sesuaikan dengan ip yang anda gunakan
kemudian akses administator portal untuk login sebagai admin
ini tampilan dashboardnya (Keren kalo menurut saya)
okee cukup sekian dulu untuk tutorial installasi oVirt 4.0.5 ini, nanti akan saya lanjutkan Installasi Ovirt Node (Hypervisor)
semoga bermanfaat……
Keep learning & Istiqomah 🙂
