Promox 8.0 Released with enhanced features

Proxmox VE 8.0 Released with Enhanced Features

Proxmox VE is an open-source server virtualization management solution that enables users to handle virtual machines (VMs), including Windows and Linux machines, as well as Linux containers. It runs on the Debian Linux distribution and brings together two reliable virtualization technologies: KVM (Kernel-based Virtual Machine) and LXC (Linux Containers), managed via an intuitive web interface. The Proxmox platform optimizes efficiency and simplifies management tasks within virtual environments, facilitating the deployment, administration, and monitoring of VMs, containers, network settings, storage systems, and more, all from a unified and integrated platform.

Proxmox also offers advanced features such as seamless live migrations of VMs without downtime, high availability, and automated backups, making it a reliable choice for managing virtual environments in small businesses and large enterprises alike. Its open-source environment encourages community involvement and offers an affordable virtualization solution.

This enables improved user access management, which leads to a more protected environment. Integration of the host network bridge and VNet access into the ACL system simplifies the administration of network resources.

Improvements in the Web UI

Proxmox VE 8.0 brings a host of enhancements to its web interface, delivering an improved user experience:

  • The GUI now considers the complete Proxmox VE 8.0 and brings a host of enhancements to its web interface, delivering an improved user experience:
  • The GUI now considers the complete Proxmox VE cluster subscription status when selecting the Ceph repository. This intelligent design ensures your cluster’s optimal performance.
  • Based on user feedback, the dark color scheme introduced in Proxmox VE 7.4 has been refined. This visually appealing and straightforward interface improves usability.
  • The Markdown parser has been improved, providing better rendering of formatted text within the web interface.
  • Privilege checks have been aligned more accurately, ensuring proper authorization for various actions.
  • Localization of size units and language selection has been implemented, catering to users across different regions and languages.

Proxmox VE 8 Introduced New Features for VMs

Proxmox VE 8.0 introduces substantial enhancements for virtual machines, enhancing their functionality and performance:

  • Version 8.0 of QEMU introduces significant enhancements, such as initial support for NetBSD and OpenBSD. The adoption of Rust-based implementation for the virtiofsd codebase further enhances performance and reliability.
  • Issues with volume size information, Nvidia grid drivers, and SMBIOS UUID for Nvidia vGPU passthrough have been resolved, ensuring that VMs operate and perform without interruption.

Container Improvements in Proxmox VE 8.0

Proxmox VE 8.0 not only focuses on VMw but also offers significant improvements for containers:

  • The handling of /etc/machine-id on clone operations has been fine-tuned, ensuring the proper functioning of containers.
  • The cgroup limit has been set to 99.6% of configured memory, providing an effective safeguard against Out-of-Memory (OOM) conditions and optimizing memory utilization.

Virtual Guests Improvements in Proxmox 8

Proxmox VE 8.0 features several enhancements to enhance the experience for virtual guests:

  • The validation of the provided name of the clone now occurs in the frontend, enhancing the user experience by identifying invalid names at an early stage.
  • Config files in /etc/pve/mapping and Mapping.* privileges have been added, enabling cluster-wide mapping of PCI/USB devices.
  • Various improvements have been made to cloud-init options, providing enhanced flexibility and customization for virtual guest configurations.

HA Manager Improvements in Proxmox VE 8.0

The HA Manager in Proxmox VE 8.0 has undergone stability improvements, particularly in manual maintenance mode. The following enhancements have been implemented:

  • A fix has been implemented to prevent the loss of a maintenance mode request if the node rebooted is the active Cluster Resource Manager (CRM) at the moment.
  • Safeguards have been implemented to prevent a node in maintenance mode from exiting prematurely or self-fencing if a shutdown policy other than’migrate’ is in place.
  • The ha-rebalance-on-start utility has been enhanced to ignore running services, preventing unnecessary shutdowns and migrations..

Improved Cluster Management in Proxmox VE 8

Managing Proxmox VE clusters has never been easier with the following improvements:

The rsync invocation used when joining nodes via ssh has been adapted to align with changes in rsync CLI argument parsing in Bookworm. This ensures seamless node joining, providing a more efficient and effective management experience.

Backup and Restore Improvements in Proxmox VE 8.0

Proxmox VE 8.0 brings performance improvements to backup processes and enhances the backup and restore experience:

  • The performance of zstd backups on fast disks has been improved by removing the –rsyncable flag during invocation, leading to faster backup operations and reduced data protection time.
  • The “storing login ticket failed” error message, which caused confusion during backups to Proxmox Backup Server, has been suppressed to avoid unnecessary confusion.
  • During web interface restores, VM/CT name validation now occurs on the client-side before API requests, helping to identify invalid names at an early stage.
  • Backup sorting in the web UI is now based on date, with the addition of the VMID as an extra column for users who prefer the previous sorting by VMID followed by date.
  • An issue where the backup job editor window did not always display the selected guests has been resolved.
  • The web UI now allows adjustment of the fs-freeze-on-backup option of the QEMU guest agent, providing control over whether the filesystem should be frozen for backups.
  • The permission model for backup jobs has been improved, requiring the Datastore.Allocate privilege on the target storage for backup job edits and root privileges for editing backup jobs with dumpdir.
