You've come to the right place if you're looking for a free alternative to VMware vSphere, Microsoft Hyper-V, and Citrix XenServer. In this article, I'll tell you about Proxmox VE, a free virtualization platform. And in a separate article, I'll discuss how to choose a server for Proxmox VE . So, brew something tasty, and let's get started.
And yes, this is an article from a series: the Server Mall blog has done detailed analyses of other popular hypervisors:
Proxmox Virtual Environment (Proxmox VE, Proxmox, "Prox") is an open source platform based on the software solutions QEMU (Quick Emulator), KVM (Kernel-based Virtual Machine) and LXC (Linux Containers), which allows you to divide the physical resources of the server and create virtual machines, containers and clusters, as well as virtualize storage, networks wordpress web design agency and manage them through a WEB interface and CLI (Command line interface).
To put it simply, Proxmox is a type 2 hypervisor. That is, between the server hardware and Proxmox there is a layer in the form of a Debian host operating system based on the modular Linux kernel.
A hypervisor is a mezzaluna or a knife that cuts a pizza (server) into several pieces (virtual machines) . You can read more about the similarities between pizza and virtualization in my other article " How to choose a server for virtualization "
Interesting fact! Yes, Proxmox runs on Debian OS, which makes it a Type 2, but some people think that Proxmox is a Type 1 because it uses KVM. Some even consider it a shell for KVM and LXC hypervisors. So don't be surprised if you come across a different point of view - this is a debatable topic.
The first version of Proxmox VE was released in 2008, and since then the platform has been continuously developed, updated and popularized. As of 2022, there are more than 600,000 Proxmox hosts operating worldwide ; and most importantly, it is free (distributed under the GPLv2 license). Only some repositories and additional support are sold.
If you understand virtualization or have worked with the PVE platform, then feel free to move on to the next article heading.
But if you1 lvljust diving into virtualization and/or want to refresh your memory on PVE, then below will be a cheat sheet with everything you need. Learn English, friends
Pros and Cons of Proxmox
Pros of Proxmox
Cons of Proxmox
Free and open source.
Convenient web control panel.
Possibility of using different types of storage (local, NFS, ZFS, etc.).
Built-in backup and snapshot system.
QEMU/KVM Virtual Machines and Linux Container are two types of virtualization technologies supported by Proxmox VE (let's consider containers as virtualization);
Host System Administration — about tasks performed on the Proxmox VE host, such as Package Repositories , Network Configuration , System Software Updates , External Metric Server , Disk Health Monitoring , Logical Volume Manager (LVM) , ZFS on Linux ;
Cluster Manager — combining Proxmox VE hosts into clusters;
Once you have created your cluster, you can configure High Availability for your virtual machines and containers;
Storage — an overview of all supported storage technologies in Proxmox VE: Ceph RBD , ZFS , User Mode iSCSI , iSCSI , ZFS over iSCSI , LVM , LVM thin , GlusterFS , NFS and Proxmox Backup Server ;
Setting up a hyperconverged infrastructure with Ceph Cluster deployment ;
Backup and Restore - how to use the built-in backup manager;
Firewall - a detailed description of the operation of the built-in Proxmox VE Firewall;
User Management — about how authentication and permissions work in Proxmox VE;
Developer Documentation - a guide on how to access the source code and how to submit patches to ensure your improvements are included in the next Proxmox VE release.
Proxmox Features and Benefits
First of all, Proxmox is not perfect (who doubted it?).
Secondly, PVE is free and open source software (like from small businesses on a budget).
Complete freedom has its advantages (I'll tell you about them below) and disadvantages: PVE can be set to almost any "calculator", which will lead to poor performance. And if you poke around in the settings, it will get even worse Therefore, going beyond the basic tasks, do not expect user-friendliness in ProxyMox at the level of a bitten apple.
For example. In the days of Windows 2008, when using it as a guest system, it was necessary to select the parameters of the virtualized hardware (disk controller, network card) and driver versions. And the Ballooning technology (shared RAM for virtual machines) did not work very stably.
