Overview of this book

Proxmox is an open source server virtualization solution that has enterprise-class features for managing virtual machines, for storage, and to virtualize both Linux and Windows application workloads. You'll begin with a refresher on the advanced installation features and the Proxmox GUI to familiarize yourself with the Proxmox VE hypervisor. Then, you'll move on to explore Proxmox under the hood, focusing on storage systems, such as Ceph, used with Proxmox. Moving on, you'll learn to manage KVM virtual machines, deploy Linux containers fast, and see how networking is handled in Proxmox. You'll also learn how to protect a cluster or a VM with a firewall and explore the new high availability features introduced in Proxmox VE 5.0. Next, you'll dive deeper into the backup/restore strategy and see how to properly update and upgrade a Proxmox node. Later, you'll learn how to monitor a Proxmox cluster and all of its components using Zabbix. Finally, you'll discover how to recover Promox from disaster strikes through some real-world examples. By the end of the book, you'll be an expert at making Proxmox work in production environments with minimal downtime.

Migrating an LXC container

As of Proxmox VE 5.0, live migration of LXC containers is not possible. The container must be turned off before it can be moved. This is not a limitation of Proxmox but rather the LXC technology itself. To migrate a container, right-click on Container to open the Context menu, and then select Migrate or click on the Migrate button in the top-right corner of the GUI to open the Migration dialog box:

Select a destination node from the Target node drop-down list. Check the Restart Mode box to auto-restart the container after the migration is complete. Click on the Migrate button to initiate the migration. The migration process will auto-stop the container, migrate it to the destination node, and then auto-start it at the end of the process.

Live migration is under heavy development by LXC, so we should expect it in the mainstream LXC package in the near future. To some of us, the lack of this feature may be a huge deal breaker, especially in a container-dominant environment...
