For the first time also for RISC-V containers: Proxmox VE 7.4 is here

The new Proxmox Virtual Environment (VE) 7.4 is based on Debian 11.6 (“Bullseye”). An updated LTS kernel 5.15 is used as the standard Linux kernel, but Proxmox VE 7.4 can also work with a kernel 6.2 if desired. On this foundation, the developers use the current open source technologies for the file system (OpenZFS 2.1.9), Linux containers (LXC 5.0.2) and virtual machines (QEMU 7.2). Ceph Quincy 17.2.5 or Ceph Pacific 16.2.11 provides the virtual memory. Ceph Octopus no longer supports Proxmox VE since version 7.3.

detail improvements

QEMU 7.2 fixes problems with Windows guests loaded from a German ISO during VirtIO driver installation. Problems with iSCSI under high load and rare crashes of VMs during intensive operations on virtual IDE/SATA disks have also been fixed.

LXC 5.0.2 makes it possible via the kernel function binfmt_misc also run RISC-V containers (risc32 and risc64). After installing the qemu-user-static and binfmt-support packages, you can use a RISC-V based rootfs image on Proxmox VE 7.4 and start it as a container directly on an x86_64/amd64 Proxmox VE host.

Customizable dark machinations

Proxmox VE 7.4 now has a fully integrated Proxmox Dark theme for its web interface, based on the Crisp Light theme. The system uses the CSS Media function “prefers-color-scheme” to recognize whether users prefer light or dark designs. Individual preferences can also be queried via the settings of the operating system or browser, alternatively the user can switch between the color designs manually in the web interface.

All guests can now be displayed sorted by their names and not just by their VMIDs. The high-availability Cluster Resource Scheduler (CRS) stack has been enhanced to automatically balance VMs and CTs at startup, not just at recovery. Administrators can now switch individual Proxmox VE 7.4 nodes to maintenance mode manually (without restarting) using a CRM command. The system outsources all HA services to other nodes until the node switches back to normal operating mode.

Availability

Proxmox Virtual Environment 7.4 is open source software under the AGPLv3 license. An ISO image for installation is now freely available. For companies, Proxmox Server Solutions GmbH also offers enterprise support from 105 euros per year and CPU.
