(You could probably use qemu-img or other tools to grow it further. Similar to VHD/VMDK/VDI formats used by other software, QCOW2 is a "dynamically allocated" image format which omits free space – even though the file is only 190 MB, the actual capacity of the virtual disk is 2.4 GB. img file extension (typically used for "raw" disk images), the file contains a virtual disk in the special QCOW2 format used by Qemu – it isn't a raw 1:1 image like. img file could just as well contain an ordinary OS installation without any of the usual "live" SquashFS constructions.) (It's not a "live boot" image in the sense of liveCDs/liveUSBs an. Point Qemu at the file as the VM's system disk and it should boot. In that case it uses the hardware virtualisation technology to virtualise guests. However, it is more often used as a virtualiser in collaboration with KVM kernel components. Looks like it already is a VM filesystem image. QEMU is a machine emulator that can run operating systems and programs for one machine on a different machine. My understanding of the downloaded image file is that it is sort of a live-boot image, although not clear as to how to add dedicated storage to it, to create a VM specific filesystem s.t.
