Qemu images
Qumu disk images
There two types of images:
- raw: faster, static and take the whole allocated space, can be created with dd or fallocate.
- qcow: less performant, dynamic copy-on-write and supports snapshoting. Does not play well with Btrfs, COW on COW.
- Overlay storage images are a way to create images from other images.
- Qemu images can be resized or converted to other formats with
qemu-img.
