That the product is free and still has all the features you expect is a huge benefit.
Proxmox VE offers quick deployment, easy hardware integration, high data protection, and supports various operating systems, enhancing security and performance. Valued features include live backups and linked clones. Its affordability and open-source nature attract diverse users. Despite requiring manual commands, lacking an easy upgrade process, and needing improvements in disk management and cloud integration, Proxmox VE excels in VM migration. Compatibility with non-English systems and scalability could benefit from enhancements.
