2. Log in using the root account and password you set during installation.
3. Configure storage:
   1. Go to Datacenter > Storage.
   2. Add a new storage type (e.g., ZFS, Ceph, LVM).
4. Setup a virtual machine:
   1. Navigate to Datacenter > Node > Create VM.
   2. Follow the wizard to configure VM settings, including OS, disk, CPU, and network.
5. Setup a container:
   1. Navigate to Datacenter > Node > Create CT.
   2. Follow the wizard to configure container settings, including OS template, disk, and network.

Usage and Performance

Once Proxmox VE is set up, you can start using it to manage your virtual environment. Here are a few real-world examples:

1. Running Multiple Operating Systems

Proxmox VE allows you to run multiple operating systems on a single physical server. For example, you can have a VM running Windows Server for Active Directory and another VM running Linux for web services. This setup maximizes the utilization of your hardware resources.

2. Optimizing Performance

To optimize the performance of your virtual environment, consider the following tips:

• Allocate sufficient resources (CPU, memory, disk) to each VM/container based on its workload.
• Use SSDs for storage to improve disk I/O performance.
• Enable network bridging for high-performance networking between VMs/containers.
