VMmanager 6: Administrator guide

Server requirements

Hardware requirements


A server must be physical or virtual based on KVM virtualization.

A server has to meet the following requirements:


MinimumRecommended
CPU2 GHz3 GHz
Cores22
RAM2 Gb4 Gb
Disk space40 Gb40 Gb

Note

The more virtual machines will be created on the server, the more RAM will be consumed.

System requirement


Operating system — CentOS 7 x64. Install the panel on a fresh installation of the operating system without third-party repositories and additional services. 

Network settings


Allow incoming connections to ports:

  • 22/tcp — SSH service. This port must be available to all cluster nodes and, if necessary, for the public network;
  • 5900-6900/tcp — QEMU VNC. If access to VNC is only provided through the server with VMmanager 6, the range of ports must be open for the network integrating the cluster nodes;
  • 16514/tcp — libvirt virtual machines management service;
  • 49152-49261/tcp — libvirt migration services;
  • 443/tcp — HTTPS.

Note

We do not recommend disabling the firewalld service. Disabling the service can lead to malfunctioning of the control panel.
