Build simplefs inside vm. Based on xfstests-bld (git://git.kernel.org/pub/scm/fs/ext2/xfstests-bld.git). I do this for several reasons: - testing (without panic on desktop) - new developer, could just use this scripts, to see how it works - various tests using new kernels How it works: - cd appliance/; sudo ./gen-image; cd - - sudo ./kvm-sfs /src/oss/linux-vms/arch/x86/boot/bzImage /path/to/simplefs And you are done!
