With QEMU 7.2, LXC 5.0.2, ZFS 2.1.9, an optional Kernel 6.2, a dark theme, and other features, Proxmox Virtual Environment 7.4 has been released.

VIENNA, Austria – March 23, 2023 – Enterprise software developer Proxmox Server Solutions GmbH (henceforth "Proxmox") released version 7.4 of its server virtualization management platform, Proxmox Virtual Environment, today. The new version includes a focus on improved usability, bringing even more management tasks to the web interface.

Highlights in Proxmox Virtual Environment 7.4

  • Proxmox VE 7.4 is based on Debian 11.6 (“Bullseye”), but uses a newer, long-term supported Linux kernel 5.15 and includes updates to the latest versions of leading open-source technologies for virtual environments, such as QEMU 7.2, LXC 5.0.2, and ZFS 2.1.9. The platform supports Ceph Quincy 17.2.5 as default for new installations or optionally Ceph Pacific 16.2.11.
  • By default, Proxmox VE uses a newer, long-term supported Linux kernel 5.15. Optionally, Linux kernel 6.2 can be installed, providing support for the current features of the latest hardware. The kernel can be installed via the shell by selecting the pve-kernel-6.2 meta package. After a reboot, the new kernel will be activated.
  • Dark theme: A fully-integrated "Proxmox Dark" theme variant is now available for the web interface and the lovers of darkness. The theme is based on the Crisp light theme. To detect if a user has requested light or dark color themes, the CSS media feature prefers-color-scheme is used. Through settings in the operating system or their browser, users can indicate their preferences. However, users can switch between the color schemes manually in the web interface as well.
  • Ceph OSD: The web interface and the API now display detailed OSD information. This reduces work for administrators, as they no longer have to gather the necessary information from various places.
  • Task logs can be downloaded as text files in the GUI, which helps to make further inspection easier.
  • Sorting of the resource tree: VMs or containers can now be sorted by their names or by VMID, by selecting the appropriate sort-order. Especially in large clusters, sorting all guests by name can provide a better overview for users who rely on them.
  • HA Manager: By adding a CRM command, an online node can be switched manually into maintenance (without reboot). Also, the support for the HA Cluster Resource Scheduler (CRS) stack was extended and can now rebalance VMs & containers automatically on start, not only on recovery.

Further Notable enhancements

  • To avoid the browser error "Connection reset", HTTP requests are automatically redirected to HTTPS. This can prevent confusion, especially after setting up a Proxmox VE host for the first time.
  • When users select the storage view for a Proxmox Backup Server storage, they can then use the columns for encryption and verification status for sorting.
  • Containers: The open-source architectures riscv32 and riscv64 can be used for LXC containers. Additionally, some container templates for amd64 were updated to newer upstream versions.
  • Virtual guests: Renaming the "Bulk Stop" action to "Bulk Shutdown" reflects the actual behavior of this action.
  • HA Manager: In preparation for the dynamic load scheduling in clusters, the high availability manager abstracts and unifies the needed resources (CPU, memory) of the different HA services (containers, VMs).
  • Improved management for Proxmox VE clusters: the Proxmox Offline Mirror tool now supports using HTTP proxies for fetching updates.
  • Storage: With the help of the option content-dirs, the specific subdirectories for content-types—for example isos, container templates, backups, guest disks—can be overridden with custom values.
  • Access Control: By refactoring the ACL computation, performance significantly improved—up to a factor of 450—in setups with many entries and huge user bases or with many access control rules.
  • Notifications for new package updates can optionally be disabled, further improving the administration experience .
  • Installation ISO: During installation, the UTC timezone can be selected, facilitating the synchronization of hosts or clusters that are distributed across multiple geographic locations.
  • Localization (i10n): Translations for Arabic, French, German, Italian, Japanese, Russian, Slovenian, and Traditional Chinese were improved.
