Proxmox VE provides the means to implement a virtual server system turnkey web-based industrial-grade software to manage hundreds or even thousands of virtual machines.

The distribution has built-in tools for organizing backups of virtual environments and clustering support available out of the box, including the ability to migrate virtual environments from one node to another without stopping work.

Among the features of the web interface: support for secure VNC console; access control to all available objects (VM, storage, nodes, etc.) based on roles; support for various authentication mechanisms (MS ADS, LDAP, Linux PAM, Proxmox VE authentication).

Main new features of Proxmox VE 7.4

The new version adds the ability to automatically rebalance virtual machines and containers at startup stage, and not just during recovery.

Added a CRM command to the High Availability Manager to manually put an active node into maintenance mode without requiring a reboot. In preparation for the implementation of a dynamic load scheduling system in the cluster, the resources (CPU, memory) of various HA services (virtual machines, containers) were unified.

Added the "content-dirs" option to the repository to override the content-type in certain subdirectories (for example, iso images, container templates, backups, guest disks, etc.).

The ACL calculation has been redesigned and the performance of access control rules on systems with a large number of users or large ACLs has been significantly improved.

Of the other changes that stand out:

  • Added the ability to disable notification of package updates.
  • The installation ISO provides the ability to select a time zone during the installation process to facilitate synchronization of geographically separated hosts or clusters.
  • Added support for riscv32 and riscv64 architectures in LXC containers (requires installation of qemu-user-static and binfmt-support packages).
  • Updated system versions in container templates for the amd64 architecture.
  • Improved options for editing backup related jobs.
  • Added support for adding local storage types hosted on other cluster nodes.
  • Added a node selection interface to the Add Storage wizard for ZFS, LVM, and LVM-Thin storage.
