serene

Collection of scripts to automate VM creation for testing Linux kernel builds.

Workflow example

1. Pull the Linux source code

$ git submodule update --init -- src/linux

2. Create rootfs and host configurations

$ ./tools/create-rootfs.sh

3. Make default kernel config

$ ./tools/make-defconfig.sh

4. Build the Linux kernel

$ ./tools/build-kernel.sh

5. Start VM

$ ./tools/start-vm.sh

6. SSH into vm

$ ssh test

7. Stop VM

$ ./tools/stop-vm.sh

Arguments to the VM

Optional arguments to start-vm.sh:

-c: CPU security related parameters (smep, smap)
-k: Kernel security (kpti=1, kaslr)

Examples:

$ ./tools/start-vm.sh -c smep
$ ./tools/start-vm.sh -c smap
$ ./tools/start-vm.sh -c smep,smap
$ ./tools/start-vm.sh -k kpti=1
$ ./tools/start-vm.sh -k kaslr
$ ./tools/start-vm.sh -k kpti=1,kaslr
$ ./tools/start-vm.sh -c smep,smap -k kpti=1,kaslr
