How to Install KVM on Dedicated Server

In this article, you will learn How to Install KVM on Dedicated Server. Virtualization is a simulated platform or an environment on the host. This simulated virtual environment can be an operating system or a development environment, etc. The virtualizor allows you to use your hardware optimally and get the most out of it.

What is KVM?

KVM stands for Kernel-based Virtual Machine. Kernel-based virtualization is actually supported for your virtual hardware and can manage it. This virtualizor is implemented by the new generation of AMD and AMD CPU processors.

Redhat is one of the main developers of KVM virtualization. The virtualizor is installed on the Linux operating system or the host server. But due to its special technology, it creates virtual servers with its own core or kernel. This allows you to install a virtual server or any operating system you need, such as Windows, BSD, Linux, etc., and use it easily. KVM provides high quality for the guest operating system because it provides dedicated resources to its virtual server.

One of the advantages of the KVM virtualizor is support for Windows and Linux.

Requirements to Install KVM on Dedicated Server

1- Disable SELinux

2- Installing a 64-bit operating system

3- VT enabled to boot from BIOS

4- Create partitions as follows:

• Root partition: 80-100 GB
• SWAP: + 4 GB
• Storage: All the remaining space on the hard disk.

5- Supported storage types include LVM File, Thin LVM, ZFS, ZFS Thin ZFS Compressed, ZFS Thin Compressed, and Ceph Block Device.

Installing KVM on Dedicated Server

Before starting the KVM installation process, we recommend that you visit our Cheap Dedicated Server plans. Then follow the steps below to install KVM on a dedicated server.

First, connect to your server using Putty or SSH. Then run the following commands to install KVM:

wget -N http://files.virtualizor.com/install.sh
chmod 0755 install.sh
./install.sh [email protected] kernel=kvm

It may take some time to download and install KVM depending on your internet speed, so we recommend that you be patient until the installation process is completed. As below, you will be asked if you want to reboot. Type “y” and press enter.

How to Login into the KVM

After the Virtualizor has been successfully installed, it is necessary to open the browser and type one of the following addresses to access it:

https://Your-Server-IP:4085/
http://Your-Server-IP:4084/

After successfully logging in, you will see the Virtualizor dashboard as shown below:

How to Configure KVM on Dedicated Server

In this section, we will teach you some configurations and settings related to Virtualizor. It is necessary to allow access to ports 4081 – 4085 by running the following commands.

For RHEL & CentOS versions lower than 7:

iptables -I INPUT 1 -p tcp -m tcp --dport 4081:4085 -j ACCEPT
iptables -I INPUT 2 -p tcp -m tcp --dport 5900:6000 -j ACCEPT

For RHEL & CentOS versions higher than 7:

firewall-cmd --zone=public --permanent --add-port=4081-4085/tcp
firewall-cmd --zone=public --permanent --add-port=5900-6000/tcp
firewall-cmd --reload

To define the storage space, it is necessary to go to the management panel:

Virtualizor –> Storage –> Add Storage

As you can see in the picture above, you can easily create Storage by filling in the required fields.

Conclusion

In this post, you were taught How to Install KVM on Dedicated Server and how to access and configure it. Interestingly, KVM uses a combination of Security Advanced Linux (SELinux) and Secure Virtualization (sVirt) for advanced VM security and isolation. KVM can also use any standard storage supported by Linux, including some local disks and network-attached storage (NAS). Ask your questions in the comments section.
