Introduction
For those who aren’t familiar with the concept. Different hypervisors use different file formats to represent VM images and due to the fact that Proxmox uses Qemu (Quick Emulator)/KVM (Kernel-based Virtual Machine) to provide virtualization, it in turn uses Qcow2 (Qemu Copy-On-Write) as the storage file format for virtual machines data. The process to move Qcow2 files into Proxmox may not be as straight forward as it is on VMware, but its still a relatively painless process.
