Based on the recently released Debian GNU/Linux 9 “Stretch” operating system, Proxmox 5.0 “Virtual Environment” is here to introduce a bunch of new functionalities and under-the-hood improvements, and the biggest of them all is the implementation of a new Proxmox VE storage replication stack. Other noteworthy changes implemented in this major release of the Proxmox “Virtual Environment” operating system, we can mention Ceph RBD as the de-facto standard for distributed storage, which is now maintained in-house by the Proxmox team, and a new command-line tool called “qm importdisk” for simplifying the import of disks from various hypervisors, including Microsoft’s Hyper-V and VMware.
