A. Cody Schuffelen 9ca6039b03 Support generating and opening backing files ... The new functionality can be invoked through "crosvm create_qcow2 --backing_file=backing new_file". The old behavior of creating a qcow image with a particular size is still available with its original syntax. This is relevant to implement as by default something like qemu-img will create a new image that assumes the backing file is raw or qcow, while crosvm can use its knowledge of other formats (such as composite disk, and later android sparse) to determine the true size of the backing file.
