Virtualizor LXC

Today, let us see how virtualizor LXC works.

Requirements

• OS Support: CentOS 7.x or AlmaLinux 8.x
• Package manager: yum / apt-get
• Storage required: For Container’s disk creation, (DomUs) disk is required.
• If the server is from the panel then install the original/stock kernel from the OVH panel by choosing its checkbox on the last step on the OVH panel while installing OS.

Supported Storage Types

( LVM | Thin LVM | ZFS | ZFS Thin | ZFS Compressed | ZFS Thin Compressed )

Installation

Open a Shell Terminal (e.g. PuTTY) and SSH to your server. Run the following commands:

wget -N http://files.virtualizor.com/install.sh
chmod 0755 install.sh
./install.sh email=your@email.com kernel=lxc

Note:

Always provide a valid email address else the installation will fail!

Installation Parameters

• email – The Admin Email Address
• kernel – In this case, its lxc
• noos – If you don’t want to download the DomU operating system for the DomU then please add noos=true as a parameter
• lvg (optional) – If you are going to use LVM for the VPS storage. The Volume Group that will be used for the DomU (VPS) storage e.g. defaults to VG. It should have some OR ALL unallocated space to create LVMs for the VPS.
• interface – You can specify the default interface that you want to set. If not provided it will be considered as eth0.
• license – In case you are installing Virtualizor on the internal network you will need to provide the VALID license key. To get the internal license key you will need to open a support ticket.

The installation will begin immediately. It may seem that the installation has stopped if your network speed is slow, but please let it continue. You will see something like this :

After the installation is successful, you will be asked to reboot your Server. Type “Y” to reboot now or “N” to reboot later.

You will need to reboot this machine to load the correct kernel

Ports

Virtualizor uses ports from 4081 – 4085. If there is any firewall restricting this, you will need to allow these ports.

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

Login

To login to the Softaculous Virtualizor Admin Panel, visit the following URL :

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

Admin Panel

After you log in, you will see the Admin Panel Dashboard :

Create Storage

Before creating any VMs, it’s necessary to define your storage. Navigate to Virtualizor Admin Panel -> Storage -> Add Storage
You will see the following wizard :

Fill in the details and define the storage.

Virtualizor Network In LXC

Virtualizor will create a viifbr0 bridge.
viifbr0 detects the IP, Netmask, and GATEWAY from :

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

Hence if you change the above file, you will need to restart the virtualizor network :

root> service virtnetwork restart

Start Command :

root> service virtnetwork start

Stop Command :

root> service virtnetwork stop

Cant open http://IP-Address:4084

Please check if your iptables firewall is running You can disable it with the following command :

root> service iptables stop
