2020-05-05image: Add a new API.Mathieu Othacehe
Raw disk-images and ISO9660 images are created in a Qemu virtual machine. This is quite fragile, very slow, and almost unusable without KVM. For all these reasons, add support for host image generation. This implies the use new image generation mechanisms. - Raw disk images: images of partitions are created using tools such as mke2fs and mkdosfs depending on the partition file-system type. The partition images are then assembled into a final image using genimage. - ISO9660 images: the ISO root directory is populated within the store. GNU xorriso is then called on that directory, in the exact same way as this is done in (gnu build vm) module. Those mechanisms are built upon the new (gnu image) module. * gnu/image.scm: New file. * gnu/system/image.scm: New file. * gnu/build/image: New file. * gnu/local.mk: Add them. * gnu/system/vm.scm (system-disk-image): Rename to system-disk-image-in-vm. * gnu/ci.scm (qemu-jobs): Adapt to new API. * gnu/tests/install.scm (run-install): Ditto. * guix/scripts/system.scm (system-derivation-for-action): Ditto.

2020-04-29tests: install: Fix device usage.Mathieu Othacehe
This is a follow-up of a860eddbbddeae5d3b6fe084e29ac9fafd2d6f02. Guided installation tests are now run from an ISO image. Hence the main block device is vda and not vdb anymore. * gnu/tests/install.scm (installation-target-os-for-gui-tests): Use %minimal-os-on-vda instead of %minimal-os. (%minimal-os-on-vda): Make sure that it replicates the config of %minimal-os.

This is a follow-up of a860eddbbddeae5d3b6fe084e29ac9fafd2d6f02. If using an ISO, the main disk is vda and not vdb anymore. * gnu/tests/install.scm (installation-target-os-for-gui-tests): Use vda2 as swap partition.
2020-04-29tests: install: Increase virtual machine RAM.Mathieu Othacehe

2020-03-22tests: install: Abort when one installation step fails.Mathieu Othacehe
When marionette-eval calls fail in gui-test-program, the installation continues which results in two scenarios: - hang forever at the next marionette-eval call, - keep going and start a broken installation, which is annoying because it clears the terminal and hides the error. Make sure that gui-test-program is exited with #f return code when one of the marionette-eval calls fail. * gnu/tests/install.scm (gui-test-program): Add a new macro "marionette-eval*". Throw an exception when one on the marionette-eval calls fail.
2020-03-19tests: Accept manual installation scripts that exit with SIGTERM.Ludovic Courtès
Fixes <https://bugs.gnu.org/39926>. Reported by Maxim Cournoyer <maxim.cournoyer@gmail.com>. Previously we'd error out if the installation script exits with non-zero, which was the case because the 'reboot' program would typically not get a reply, and thus would eventually be killed by PID 1 as the system is brought down. * gnu/tests/install.scm (run-install)[install]: Expect SCRIPT to exit with SIGTERM in addition to exiting with zero.
