Proxmox VE is a complete, open-source server management platform for enterprise virtualization. It tightly integrates the KVM hypervisor and Linux Containers (LXC), software-defined storage and networking functionality, on a single platform. With the integrated web-based user interface you can manage VMs and containers, high availability for clusters, or the integrated disaster recovery tools with ease.
By combining two virtualization technologies on a single platform, Proxmox VE is giving maximum flexibility to your production environment. Use KVM full virtualization for Windows and Linux images, and lightweight containers to run conflict-free Linux applications.
Proxmox VE is a powerful open-source server virtualization platform to manage two virtualization technologies - KVM (Kernel-based Virtual Machine) for virtual machines and LXC for containers - with a single web-based interface. It also integrates out-of-the-box-tools for configuring high availability between servers, software-defined storage, networking, and disaster recovery.
LXC is an operating-system-level virtualization environment for running multiple, isolated Linux systems on a single Linux control host. LXC works as a userspace interface for the Linux kernel containment features. Users can easily create and manage system or application containers with a powerful API and simple tools.
You can access Proxmox VE on mobile devices either via an Android app or via the HTML5-based mobile version of the web interface. The Proxmox VE Android app is based on the Flutter framework, and allows you to access your Proxmox VE server and manage your cluster, nodes, VMs, and containers. The Proxmox VE HTML5 mobile client enables you to manage Proxmox VE on the go, including access to the SPICE and HTML5 console. This allows you to manage VMs and containers, and view their configuration.
To simplify the management of a cluster, you can carry out maintenance tasks cluster-wide, from any node. The integrated web-based management interface gives you a clean overview of all your KVM guests and Linux containers across your cluster. You can easily manage your VMs and containers, storage or cluster from the GUI. There is no need to install a separate, complex, and pricey management server.
The resource manager, Proxmox VE HA Manager, monitors all VMs and containers in the cluster and automatically comes into action if one of them fails. The Proxmox VE HA Manager works out-of-the-box. Zero configuration is needed. Additionally, the watchdog-based fencing dramatically simplifies deployment. The entire Proxmox VE HA Cluster can be easily configured from the integrated web-based user interface.
Backups are a basic requirement for any sensible IT environment. The Proxmox VE platform provides a fully integrated solution, using the capabilities of each storage and each guest system type. Backups can be easily started with the GUI or with the vzdump backup tool (via command line). These backups are always full backups - containing the configuration of VMs and container, and all data.
The integrated backup tool (vzdump) creates consistent snapshots of running containers and KVM guests. It basically creates an archive of the VM or container data and also includes the configuration files.
Proxmox Backup Server is our enterprise-class backup solution, that is capable of backing up VMs, containers, and physical hosts. Support for this is fully integrated into Proxmox VE, meaning you can seamlessly back up and restore guests using the same common interface that the other storage types use.These backups are incremental, only transferring newly changed data over the network. This is highly beneficial in terms of network bandwidth and backup job run time. Data can also be easily encrypted on the client side, so that your backed up data is inaccessible to attackers.
Oftentimes, only a single file or directory is needed from a backup. From the Proxmox VE web interface, you can securely search for and restore individual files or directories from a VM or container backup.
You can set up firewall rules for all hosts inside a cluster, or define rules for virtual machines and containers only. Features like firewall macros, security groups, IP sets and aliases help to make that task easier.
Before you shutdown the hardware node you must cleanly shutdown all OpenVZ containers and all KVMs. To avoid having to do this manually, Proxmox will issue all running containers and VMs the shutdown command as part of the hardware nodes shutdown procedure. Proxmox also gives us the option to specify which containers and VMs should be started when the hardware node is turned on. This means that the final part of the hardware nodes startup sequence will be to start your containers and VMs. Depending on your environment, this may need to be done in a specific order. For example you may wish your database VM or container to be started before your web application.
To enable the automatic startup of an OpenVZ container or VM you must specify the Start at boot attribute in the Proxmox web interface. Simply click on the Options tab of the container or VM and double click the Start at boot attribute.
It is sometimes necessary to specify which containers and VMs startup first and how long the hardware node should wait until issuing the next startup command. This is easy for KVMs as this can be done through the Proxmox web interface.
Unfortunately Proxmox has not provided this functionality in the web based GUI for OpenVZ containers. To specify the order for a container we need to use the command line on the Proxmox hardware node.
Login to your Proxmox hardware node as the root user and issue the below command to set the machine startup order. You will need to change [PRIORITY] to the priority value to use and [VMID] to the ID of the container.
You must have already enabled Start at boot for the container to start up. Any containers which have the Start at boot attribute enabled but no Start/Shutdown order attribute will be started after all containers with a Start/Shutdown order attribute set have been processed.
Proxmox Virtual Environment (Proxmox VE or PVE) is a hyper-converged infrastructure open-source software. It is a hosted hypervisor that can run operating systems including Linux and Windows on x64 hardware. It is a Debian-based Linux distribution with a modified Ubuntu LTS kernel and allows deployment and management of virtual machines and containers. Proxmox VE includes a web console and command-line tools, and provides a REST API for third-party tools. Two types of virtualization are supported: container-based with LXC (starting from version 4.0 replacing OpenVZ used in version up to 3.4, included), and full virtualization with KVM.It includes a web-based management interface.
Proxmox VE is an open-source server virtualization platform to manage two virtualization technologies: Kernel-based Virtual Machine (KVM) for virtual machines and LXC for containers - with a single web-based interface.The source is open, based on the GNU AGPL, v3. The company sells optional subscription-based customer support. With a subscription, users get access to an enterprise software repository.
Proxmox VE use bridge model by default. Bridges are like physical network switches that work in OSI layer 2 (OSI 2), but implemented in software. All virtual machines or Linux containers can share a single bridge, or you can create multiple bridges to isolate (segment) the network. For the bridge itself you can choose between Linux native bridge and/or Open vSwitch bridge. In addition to that you can also natively use a bond (aggregation): Linux native or Open vSwitch kind, with the mode that is best suited for you (e.g. balance-rr, active-backup, balance-xor, broadcast, LACP, balance-tlb, balance-alb).
PVE supports clones and templates. Clones are exact copy of the VM/container and a template can be created from VM/Container. One can use the template(s) to clone them to the new VM/container.
I wonder the limitation of OpenVZ containers/VMs stored to local repository only. How one can migrate a system in OpenVZ container to another machine, if the host machines aren't sharing a storage to run VMs from?

Depending on the filesystem size, it can take a while... although if the deltas are small for the second rsync pass, the perceived "downtime" caused by the migration is usually only a few seconds... with network connections maintained. For offline migrations, where the container is shutdown completely and then restarted on the target host, downtime is generally only 20-30 seconds... depending on how long it takes to start up the container.I would imagine that Proxmox VE uses vzmigrate or their own script designed similar to vzmigrate, but I'm not positive.

Proxmox is my preferred hypervisor to deploy various containers and VMs. Sometimes, I want to create a VM inside another VM. Meaning - I just want to host a guest hypervisor(i.e VM) in my physical Proxmox hypervisor. Have you ever wondered how to setup a guest hypervisor in a host hypervisor? In this guide, I will show you how to enable nested virtualization in Proxmox VE and then enable VT-X in the guest hypervisor. 2b1af7f3a8
