In the rapidly evolving landscape of open-source virtualization, incremental updates often fly under the radar—until one arrives that promises to change the way we handle storage, snapshots, and performance. The latest buzz in developer and sysadmin circles revolves around a specific, technical identifier: .
: The open-source, Linux-native virtualization module that turns the host operating system into a type-1 hypervisor.

Ephemeral virtual machines used in GitLab or Jenkins pipelines often boot, run tests, and die within minutes. The new format’s feature ensures that after destroying a test VM, storage fragmentation remains at near-zero levels, preserving the performance of the parent image indefinitely.
: It creates a mapping between logical and physical blocks, allowing for efficient storage use .
This will create a 20GB QCOW2 file named my_new_vm_disk.qcow2 . Initially, the file will consume only kilobytes of space on your host.
Note: You must still expand the partition inside the guest OS using a tool like growpart and resize2fs .
