Early adopters report that converting their Ceph RBD-backed KVM nodes to this format reduced their back-end storage latency by 18% due to better I/O coalescing.
Perform this conversion during a maintenance window. A 500GB disk image may take 10-20 minutes to rewrite, but the performance gains are worth the downtime.

: Bind the virtual file dynamically to local volume allocations.
This is the preferred file format for virtual disk images used by QEMU and KVM. Unlike raw disk images, QCOW2 files only consume space on the physical hard drive as data is actually written to them (dynamic allocation). They also support advanced features like encryption, compression, and snapshots . Early adopters report that converting their Ceph RBD-backed
Because QCOW2 is a "copy-on-write" format, the virtual disk image starts very small and grows as the virtual machine adds data. This prevents you from wasting hundreds of gigabytes of physical storage on an empty virtual machine.
