What is Proxmox VE?

Proxmox Virtual Environment (VE) is an open-source virtualization platform that combines container-based virtualization (LXC) and full virtualization (KVM). It offers centralized management of virtual machines and containers via a user-friendly Web interface.

Why install Proxmox VE on VirtualBox?

Installing Proxmox VE on VirtualBox is often used for testing and experimentation. This allows users to discover Proxmox VE functionalities in a virtual environment, without the need for dedicated hardware.

Is VirtualBox suitable for production deployment of Proxmox VE?

No, VirtualBox is generally not recommended for production deployment. Proxmox VE is designed to be deployed on dedicated hardware or in professional virtualization environments to ensure optimum performance and high reliability.

How do I access the Proxmox VE web interface after installation?

Open a web browser and enter the IP address assigned to your Proxmox VE virtual machine, followed by port 8006 in the address bar. This will take you to the web interface, where you can log in with the credentials you defined during installation.

Does Proxmox VE support container-based virtualization (LXC)?

Yes, Proxmox VE supports container-based virtualization (LXC) in addition to full virtualization (KVM). This means greater flexibility when deploying applications in lightweight containers.
