# Verify ISO checksum (example)
sha256sum proxmox-ve_8.0-1.iso

Step 2: Create Bootable USB Drive

On Windows:

1. Download Rufus or Balena Etcher

2. Insert USB drive

3. Select Proxmox ISO and USB drive

4. Click "Start" to create bootable drive

On Linux/Mac:

# Using dd command
sudo dd if=proxmox-ve_8.0-1.iso of=/dev/sdX bs=4M status=progress

sudo apt update
sudo apt install qemu-guest-agent
sudo systemctl enable qemu-guest-agent
sudo systemctl start qemu-guest-agent

5. Shutdown VM: After installation, shutdown VM from Proxmox

Step 9: Create Linux Container (LXC)

LXC containers are lighter and faster than VMs:

1. Click Create CT (Container)

2. General Tab:

3. Template Tab:

4. Root Disk:

5. CPU:

6. Memory:

7. Network:

8. DNS:

9. Confirm and Finish

Step 10: Network Configuration

Create VLAN:

1. Go to Datacenter → Network

2. Create bridge for VLAN:

# Edit network configuration
nano /etc/network/interfaces

# Add VLAN bridge
auto vmbr1
iface vmbr1 inet static
    address 192.168.2.1
    netmask 255.255.255.0
    bridge_ports none
    bridge_stp off
    bridge_fd 0

3. Apply changes: ifreload -a

Step 11: Backup Configuration

Setup Backup Storage:

1. Go to Datacenter → Storage

2. Click Add → Directory

3. Configure:

Schedule Backups:

1. Select VM/Container

2. Go to Backup tab

3. Click Add

4. Configure:

Step 12: Advanced Configuration

Enable Hardware Acceleration:

# Check CPU virtualization support
egrep -c '(vmx|svm)' /proc/cpuinfo

# Enable nested virtualization
echo "options kvm-intel nested=1" >> /etc/modprobe.d/kvm.conf

Configure Firewall:

1. Go to Datacenter → Firewall

2. Enable Firewall

3. Add rules as needed

4. Configure Security Groups

Setup Clustering (Advanced):

For multiple Proxmox nodes:

1. Go to Datacenter → Cluster

2. Click Create Cluster

3. Add nodes with: pvecm add IP_ADDRESS

Step 13: Useful Proxmox Tips

Performance Optimization:

# Enable write-back cache for better performance
# Set in VM hardware settings

# Use VirtIO drivers for best performance
# Install virtio drivers in Windows VMs

# Allocate resources based on workload
# Monitor usage and adjust accordingly

Security Best Practices:

1. Change default SSH port

2. Use key-based authentication

3. Enable firewall

4. Keep Proxmox updated: apt update && apt upgrade

5. Regular backups

6. Strong passwords

7. Limit network exposure

Monitoring:

1. Resource Usage: Monitor CPU, RAM, disk usage

2. Alerts: Configure email alerts

3. Logs: Check system logs regularly

4. Health Checks: Monitor cluster health
