  ❄️ The Most Reliable and Secure Transfer: Everything About Cold Migration If 'Live Migration' in Proxmox VE is the pinnacle of flashy technology, 'Cold Migration' is a classic technique that boasts powerful stability. This #method , which moves resources between nodes while the Virtual Machine (VM) or Container (CT) is completely stopped, minimizes variables imposed on the system. Sometimes, a heavy and certain orthodox approach is needed more than a flashy technique. In this #lecture , we will take an in-depth look at why you should choose Cold Migration even if it means service interruption, and the internal working process behind it. 1. Definition and Core Principles of Cold Migration Cold Migration, as the name suggests, is a technology that moves resources in a 'cold' state—that is, when the power is turned off. A. Stateless Migration Unlike Live Migration, which copies running memory data in real-time, Cold Migration ignores the memory state. Since the p...

  🚀 The Magic of Zero Downtime: The Secrets of Live Migration One of the most powerful features of Proxmox VE, 'Live Migration,' is a technology that moves a Virtual Machine (VM) or Container (CT) to another physical node while it is still running. This is a magic-like feature that allows you to maintain services without interruption during system inspections, load balancing, or hardware replacements. However, for this magic to work correctly, several essential conditions must be met. In this #lecture , we will take a detailed look at the importance of 'Shared Storage' and 'Cluster Configuration,' the core prerequisites for enabling Live Migration. 1. What is Live Migration and Why is it Necessary? We explore the fundamental #concept and use cases of Live Migration, which ensures service continuity. A. The Core of Zero-Downtime Service Live Migration transfers all #data , including memory, CPU state, and disk I/O, from the source node to the target node in rea...
