The newest release is based on Debian 11.1 Bullseye
Proxmox has released version 7.1 of Proxmox Virtual Environment based on Debian Bullseye 11.1, but using a newer Linux kernel 5.13.
Proxmox VE (Virtual Environment) is a complete, open source server management platform for enterprise virtualization. It integrates the KVM (Kernal-based Virtual Machine) hypervisor and Linux Containers (LXC), software-defined storage, and networking functionality on a single platform.
One of the greatest features of Proxmox is its managed web-based interface, accessible after installation. This means that you can manage Proxmox through the web interface based on the javascript framework, and it allows the administrator to control all features.
Yesterday the Enterprise software developer Proxmox Server Solutions GmbH has released version 7.1 of its server virtualization management platform, Proxmox Virtual Environment, so let’s check what’s new.
Proxmox VE 7.1 Highlights
Version 7.1 of Proxmox Virtual Environment is based on the latest Debian 11 (Bullseye) combined with leading open source technologies for virtual environments. This includes a modern Linux kernel 5.13, LXC 4, Ceph 16.2, QEMU 6.1, and OpenZFS 2.1.
Now newly created VM’s have support for secure boot verification, allowing modern system such as Windows 11 to run. The improved VM setup wizard has new defaults for Windows 11, like q35 machine type, use of OVMF (UEFI), and added Trusted Platform Module (TPM). On top of that, if needed, multiple virtual disks can be added.
Backup jobs are now run by a new scheduler daemon and support more flexible scheduling options. You can test how various schedules will behave in the Job Schedules Simulator. From there you can select a predefined schedule and adapt it to your needs.
If you want to keep a backup indefinitely and protect it from getting deleted due to your backup retention settings, Proxmox 7.1 allows you to simply set the protected flag.
Among other things, Proxmox 7.1 now supports WebAuthn (superseding U2F) and one-time recovery keys have been added. The configuration of multiple factors for a single account is now possible. This can all be configured from the web interface. In addition to, two-factor authentication (TFA) has been further improved.
Last but not least, container templates for Fedora and Ubuntu have been updated. Support and templates for the AlmaLinux and Rocky Linux distros are now included.
As always, Proxmox 7.1 included a lot of bugfixes and improvements on many places. You can find out more details on the Proxmox VE 7.1 changes over on the official announcement.
