QEMU, the virtual machine monitor typically used with KVM, has long supported thin provisioning through both sparse raw files and the qcow2 image format. However, for thin provisioning to help both virtual machine users and host administrators, it must be supported throughout the whole virtualization stack: the guest (userspace and kernel), the host (QEMU, management interface, kernel), the storage itself. This talk will show how we implemented thin provisioning in all these layers and how the results benefit our users.
