To successfully follow this tutorial and have Proxmox 8 fully functional, you should first install Debian 12 Bookworm using our control panel. 

Once you have SSH access to your server:

Add the Proxmox VE repositories:

echo "deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription" > /etc/apt/sources.list.d/pve-install-repo.list

Add the repository key for Proxmox VE:

wget https://enterprise.proxmox.com/debian/proxmox-release-bookworm.gpg -O /etc/apt/trusted.gpg.d/proxmox-release-bookworm.gpg

Update the system repositories:

apt-get update && apt-get upgrade

Install the Proxmox VE kernel and reboot the server:

apt install proxmox-default-kernel -y systemctl reboot

After the server has rebooted, SSH back in and install the Proxmox VE packages:

apt install proxmox-ve postfix open-iscsi chrony -y

Next, configure a bridge and assign it to the main interface of the machine with the following network configuration. Replace "ens18" with the name of your server's main interface and replace IP Address and gateway.

```

Example configuration for /etc/network/interfaces

auto lo iface lo inet loopback

auto ens18 iface ens18 inet manual

auto vmbr0 iface vmbr0 inet static address 192.168.1.2/24 gateway 192.168.1.1 bridge_ports ens18 bridge_stp off bridge_fd 0 ```

If you have additional IPs and want to use them in virtual machines, you should enable IP forwarding with the following command:

echo "net.ipv4.ip_forward=1" >> /etc/sysctl.conf && sysctl -p

For the VPS configuration, set the IP to /24 at the end, and the gateway for the virtual machine will be the main IP of the node.

Add Storage to Proxmox

To add storage in Proxmox, where we will create the VPS, you must assign it to the volume group called vg0. You must go to Datacenter > Storage. Once in this section, click on Add and do it as follows:

Once this is done, all VPS should be created in the local-lvm storage, and an LVM partition will be created for each disk of each VPS.
