By reading the step-by-step guide of this article, you can easily Install Virtualizor on AlmaLinux 8. Virtualization is a creative and very practical idea and solution to create a virtual version of storage devices, servers, networks, and other resources that were once only physically available to users. You can virtualize with Virtualizor.

What is Virtualizor?

Virtualizor is a powerful web-based admin control panel for KVM, XEN, and OpenVZ virtualizers. This control panel forms a very powerful virtualization system by combining the virtualizers. One of the most important features of this powerful panel is the limitation of bandwidth for each virtual server.

Virtualizor lets you create virtual servers with just one click. Virtualizor uses the OS Template feature and through this option, installing operating systems and creating a virtual server is done in less than a few seconds.

Features of Virtualizor

1. Configure the Server on which Virtualizor is installed

2. Create or edit a Virtual Server

3. Manage Server IPs

4. Storage management

5. User management

6. Create and manage invoices

7. Manage ISO or manages to create VPS

Prerequisites

– Linux VPS Server with AlmaLinux 8 OS

– yum/apt-get

– Storage to create the VPS disks

Stay with us in the continuation of this article on How to Install Virtualizor on AlmaLinux 8.

How to Install Virtualizor on AlmaLinux 8

At first, you should open the Shell and SSH Terminals on your server and enter the following commands:

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

Remember to give the email address correctly.

What are the Virtualizor Installation Parameters?

email: The Admin email address

kernel: Its KVM

noos: Add noos=true as a parameter to avoid downloading the DomU operating system for DomU

beta: If you add beta=true as a parameter, you can test the new version of the existing Virtualizor

nested_virt: Adding nested_virt=1 as a parameter enables nested virtualization on the server. Enabling this will install a new kernel to enable nested virtualization

Ivg (optional): If you are going to use LVM for the VPS storage

interface: You can specify the default interface you want to set. If not specified, it is considered eth0

license: You will get the internal license key, by opening the support ticket

After completing the installation process, you will see the following output:

After the installation is complete, restart the system by typing and running “Y“:

/root/virtualizor.log is an installation process log file that is created after installation.

You can create a Storage and Virtual Server and also manage your server from the Admin Panel.

How to Login to the Virtualizor Admin Panel

Go to the following URL:

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

Log in with your server’s root details:

Now, you will see the following Dashboard:

At this point, you need to define storage. To do this first, go to the Virtualizor Admin Panel and select Storage from the left column, and finally click Add Storage. Then fill in the details and define the storage:

As mentioned earlier, the network interface is considered eth0 by default. Therefore, to add the desired network interface to Virtualizor, you need to do the following steps:

1) Go to Virtualizor Admin Panel

2) Select Configuration

3) Click Save Settings

Manage the Bridge 

A viifbr0 bridge is created by Virtualizor that detects the IP, Netmask, and GATEWAY from the following:

/etc/sysconfig/network-scripts/ifcfg-INTERFACE_NAME

If you change the above file, remember to restart the Virtualizor network with the following command:

service virtnetwork restart

Enter the following command to start Virtualizor:

service virtnetwork start

And you can use the following command to stop Virtualizor:

service virtnetwork stop

You can Make the bridge permanent

Run the following commands to make the bridge permanent, so that, it can be started as soon as the operating system is booted, and the network is created.

Tip: You should have the bridge-utils package on your server backup ifcfg-eth0.

– Take a Backup from ifcfg-eth0.

/etc/sysconfig/network-scripts/ifcfg-eth0 directory will contains the content below:

cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0 
BOOTPROTO=static 
TYPE=Ethernet 
HWADDR=00:25:90:98:35:90 
IPADDR=10.0.0.93 
NETMASK=255.255.255.0 
GATEWAY=10.0.0.1 
IPV6INIT=yes 
IPV6ADDR=2607:f0d0:1002:0011:0000:0000:0000:0002
IPV6_DEFAULTGW=2607:f0d0:1002:0011:0000:0000:0000:0001
ONBOOT=yes

Then you should make a copy of that directory:

cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth0.bak

Now, it is time to create the bridge file. This is the directory:

vi /etc/sysconfig/network-scripts/ifcfg-viifbr0

You should copy some sections of ifcfg-eth0 to ifcfg-viifbr0. Here is the content:

DEVICE=viifbr0 
TYPE=Bridge 
BOOTPROTO=static 
IPADDR=10.0.0.93 
NETMASK=255.255.255.0 
GATEWAY=10.0.0.1 
ONBOOT=yes 
IPV6INIT=yes 
IPV6ADDR=2607:f0d0:1002:0011:0000:0000:0000:0002
IPV6_DEFAULTGW=2607:f0d0:1002:0011:0000:0000:0000:0001

Then you should save the copied file.

To edit the ifcfg-eth0 file, go through this way:

vi /etc/sysconfig/network-scripts/ifcfg-eth0

The result would be like this:

DEVICE=eth0
HWADDR=00:25:90:98:35:90 
IPV6INIT=yes 
ONBOOT=yes 
BRIDGE=viifbr0

Tip: If the eth0 is the NIC name, then you should change the interface name in that route file to viifbr0:

root# mv route6-eth0 route6-viifbr0

As the last step, you should restart the network.

We should mention that virtnetwork is out of work now and you should restart only with the network, so use the command below:

service network restart
