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.

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:
