- Add a tool to create configured iso-images from linux distros that can be used for kvm based testing - currently generator has been tested to generate rockylinux 8.10 based qcow image that can be launched with kvm. - Tool will also generate ssh keys that are installed to generated image and can then be used to to login with therock user automatically without password. - Therock user has sudo rights to enable the install of apps that may be needed for the testing Motivation for the tool is to be able to run tests that require the execution of fully virtualized tests with images that contains also the linux kernel that is executed. This is needed because there can be errors which only occurs on certain Linux kernels and testing of those type of errors can not be done with the docker because docker images are always using the Linux kernel from the host system instead of running it from the launched Linux image. Tool was mostly generated by giving instructions and test-copmmands for the codex gpt 5.3. Full logs from me talking to myself and for the gpt 5.3 is in dir: ai-logs/ai_agent_chat_history_01.txt Usage at the moment: 1) Generate base install image: $ cd tests/kvm_tests/linux_iso_image_generator $ python build_rockylinux_8_10_iso.py build-config.json image that can be used for the testing: $ ./testing/qemu_iso_launch.sh Image generator uses following two files to customize the content of generated image: - build-config.json - templates/rocky8.ks.tmpl --> generated output/rocky8.ks Signed-off-by: Mika Laitio <mika.laitio@amd.com>

Motivation
Motivation for the tool is to be able to run tests that require the execution of fully virtualized tests with images that contains also the linux kernel that is executed. This is needed because there can be errors which only occurs on certain Linux kernels and testing of those type of errors can not be done with the docker because docker images are always using the Linux kernel from the host system instead of running it from the launched Linux image.
Technical Details
Image generator uses following two files to customize the content of generated image:
Test Plan
Purpose of this tool is to create the repeatable tests that requires running the qemu-based vm.
Usage at the moment:
$ cd tests/kvm_tests/linux_iso_image_generator
$ python build_rockylinux_8_10_iso.py build-config.json
image that can be used for the testing:
$ ./testing/qemu_iso_launch.sh
Test Result
Tool is able to generate rockylinux 8.10 based iso-image where the user can log-in with ssh
keys by following the instructions when running the command: ./testing/qemu_iso_launch.sh
Image has not yet tested with the pci-passthrough way to expose real AMD gpu for it which may be
needed by some tests.
