🔍 What is Proxmox?

3 core concepts. 1️⃣ Unified Management: Manage VMs/Containers/Storage/Network from a single web interface 2️⃣ Hypervisor: Based on Linux KVM (kernel-based virtual machine) + LXC (Linux container) technology 3️⃣ Open Source: Completely free solution based on AGPLv3 license

> 💡 Features: Most of the paid features of VMware ESXi for free + adds container support

🛠️ Step-by-step guide from installation to production

1. Installation Requirements

• CPU: 64-bit support (Intel VT/AMD-V virtualization extension required)
• RAM: 4GB+ (recommended 16GB+)
• Storage: 32GB+ SSD

2. Installation Process (Example)

# after creating a boot USB
1. select Install Proxmox VE
2. filesystem: ZFS (RAID configuration is recommended)
3. network settings: assign a static IP
4. after completion, access https://IP:8006

3. Initial setup required tasks

1. Add storage: [Datacenter] → [Storage] → [Add] → NFS/Ceph
2. network settings: create VLAN/bridge
3. clustering: pvecm create [cluster name]

💡 Real-world scenarios and examples

Create a virtual machine (Ubuntu server)

1. Select local repository
2. upload an ISO image (ubuntu-22.04.iso)
3. VM settings:
   • CPU: 4 cores
   • RAM: 8 GB
   • Disk: 50GB thin-provisioned
4. proceed with OS installation from the console

Deploy NGINX as an LXC container

pct create 100 local:vztmpl/ubuntu-22.04-standard.tar.gz \
--storage local-lvm \
--cores 2 --memory 2048 \
--hostname my-web
pct start 100
pct exec 100 -- apt install nginx

🚨 Cautions and Limitations

1. Hardware Compatibility: Certain NIC/RAID cards are not supported. (Be sure to check the Compatibility List)
2. learning curve: CLI (pvesh/pct commands) familiarization required
3. Enterprise support: Technical support available with paid subscription

—.

🌟 Advanced Utilization Tips

1. Storage optimization: zfs set compression=lz4 tank (ZFS compression ↑ storage efficiency)
2. Automate APIs:

   curl -k -X POST \
   -H "Authorization: PVEAPIToken=user@pve!tokenid=secret" \
   https://pve-ip:8006/api2/json/nodes/pve/qemu/100/status/start

3. Dyster Recovery: Recover to pvecm expected 1 in case of simultaneous cluster power failure
