Proxmox VE 6.4 Released With Single-File Restore And Live Restore

Proxmox VE 6.4 is based on Debian Buster 10.9, but using a newer, long-term supported Linux kernel 5.4. Optionally, the 5.11 kernel can be installed, providing support for the latest hardware.

Proxmox VE (Proxmox Virtual Environment) is an open-source server management platform for your enterprise virtualization. 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 can be used also on a single node and on a cluster.

With a centralized built-in web interface, users can run VMs and containers, manage software-defined storage and networking, clusters, etc.

Proxmox may not be familiar to many, but it is gaining traction due to its smart combination of open-source KVM-based virtualization, software defined storage and containers.

What’s new in Proxmox VE 6.4

The latest versions of leading open-source technologies for virtualization such as QEMU 5.2, LXC 4.0, and OpenZFS 2.0.4 have been included.

Single-File Restore

Quite often, users only need to recover a single file. This feature is now available for virtual machine and container backup archives stored on a Proxmox Backup Server, meaning an individual file or directory can be selected for restore, without having to download the entire archive. For example, to restore a file via the Proxmox VE web interface, users can open a file browser directly via the ‘File Restore’ button. A ‘Download’ button then allows the user to download files and directories, the latter being compressed into a zip archive on the fly.

Live Restore

The new live restore feature can be enabled via the GUI or through the command ‘qmrestore’. The restore of a selected VM starts immediately after activation. This feature currently works for all VMs saved on a Proxmox Backup Server storage. It is especially useful for large VMs, for example, a web server, where only a small amount of data is required for the initial operation.

Ceph Octopus 15.2.11 and Ceph Nautilus 14.2.20

Proxmox Virtual Environment supports two versions of the massively scalable, distributed storage system Ceph. Users can select their preferred Ceph version – Ceph Octopus 15.2.11 or Ceph Nautilus 14.2.20 during the installation process.

Other improvements

  • Improved ISO installer: The boot setup for ZFS installations is now better equipped for legacy hardware. Installations on ZFS now install the boot-loader to all selected disks, instead of only to the first mirror vdev, improving the experience with hardware where the boot-device is not easily selectable.
  • Container: Appliance templates or support for Alpine Linux 3.13, Devuan 3, Fedora 34, and Ubuntu 21.04. Improved handling of cgroup v2.
  • Storage: Proxmox VE 6.4 now allows for adding backup notes on any CephFS, CIFS, or NFS storage.
  • VMs: Support pinning a VM to a specific QEMU machine version. Automatically pin VMs with Windows as OS type to the current QEMU machine on VM creation.
  • GUI Enhancements: Show current usage of host memory and CPU resources by each guest in the node search-view. The firewall rules columns are more responsive and flexible by default.
