(backend variables), variables that control flow through `main.pm` (test variables) and variables that
are specified when ISO is posted into OpenQA (run variables).
Backend variables
-----------------
These variables control settings of underlying virtual machine where tests runs on. Some of them (`ARCH`, `QEMURAM`, ...) should be set per machine, others (`HDD_$i`, `HDDMODEL`, ...) should be set per test and some of them (`KEEPHDDS`, `MAKETESTSNAPSHOTS`, `SKIPTO`) should be set only during development and debugging.
| `ARCH_BASE_MACHINE` | `uefi`, `64bit`, `ARM`, ... | depends on machine | 'machine' value to be used for tests where we might want to start after a test run on a different machine. For instance, we run tests that produce x86_64 ISOs on the '64bit' machine, so `ARCH_BASE_MACHINE` for the 'uefi' machine is set to '64bit', so that we can run UEFI install tests on the 'uefi' machine with an image generated by a test run on the '64bit' machine |
| `HDDMODEL` | see `qemu-kvm -device help` (e. g. PATA = `id-hd`, SATA = `ide-hd,bus-ahci0.0`, SCSI = `virtio-scsi-pci`) | `virtio-blk` | type of device for HDD |
| `PXEBOOT` | boolean | `false`/not set | boot VM from PXE (network) |
| `QEMU` | filename, path to Qemu binary | not set | filename of Qemu binary |
| `QEMUCPU` | see `qemu-kvm -cpu help` | not set | CPU to emulate |
| `QEMUCPUS` | integer | 1 | number of processor cores to use for Qemu |
| `QEMURAM` | integer | 1024 | size of RAM to use (in MiB) |
| `QEMUTHREADS` | integer | 0 | number of CPU threads to use for Qemu |
| `QEMUVGA` | see `qemu-kvm -device help` | `cirrus` (should be set to `std` on Fedora, cirrus driver [was retired](https://lists.fedoraproject.org/pipermail/devel/2014-May/199459.html)) | display device to use for VM |
| `LIVE` | boolean | not set | technically `PACKAGE_SET`, `KICKSTART`, `MIRRORLIST_GRAPHICAL`, `REPOSITORY_GRAPHICAL`, `REPOSITORY_VARIATION` | specify that the test is running on Live system - additional steps are required (starting Anaconda...) |
| `PACKAGE_SET` | string (`minimal`, `default`, ...) | `minimal`; `default` when `LIVE` is set | nothing | sets packageset to install - you have to add appropriate needles, see `tests/_software_selection.pm` |
| `ENTRYPOINT` | filename | not set | N/A | set `ENTRYPOINT` to load specific test directly (bypass modular structure, mainly usable for testing). If you want to run more than one test, separate them with space. |
| `UPGRADE` | string (`minimal`, `desktop`, `encrypted`, ...) | not set | all except of `LIVE` and `USER_PASSWORD` | when set, do an upgrade test of specified type |
| `KICKSTART` | boolean | `false`/not set | all | when specified, do an kickstart installation (you should use `GRUB` variable to specify where kickstart file resides) |
| `MIRRORLIST_GRAPHICAL` | boolean | `false`/not set | `REPOSITORY_GRAPHICAL` | sets installation source to mirrorlist |
| `REPOSITORY_GRAPHICAL` | url to repository (without arch and `/os`, for example `http://dl.fedoraproject.org/pub/fedora/linux/development`) | not set | `MIRRORLIST_GRAPHICAL` | sets installation source to repository url in Anaconda |
| `REPOSITORY_VARIATION` | url to repository (without arch and `/os`, for example `http://dl.fedoraproject.org/pub/fedora/linux/development`) | not set | nothing | sets installation source to repository url in GRUB |
| `PARTITIONING` | string (`custom_software_raid`, `guided_delete_all`, ...) | `guided_empty` | nothing | load specified test for partitioning part (when `PARTITIONING=guided_delete_all`, `tests/disk_guided_delete_all.pm` is loaded) and optionally post-install partitioning check (if `tests/disk_guided_delete_all_postinstall.pm` exists, it will be loaded after login to the installed system). Also, if value starts with `custom_`, the `select_disks()` method will check the custom partitioning box |
| `ENCRYPT_PASSWORD` | string | not set | nothing | if set, encrypt disk with given password |
| `DESKTOP` | boolean | `false`/not set | nothing | set to indicate that Fedora is running with GUI (so for example OpenQA should expect graphical login screen) |
| `ROOT_PASSWORD` | string | `weakpassword` | nothing | root password is set to this value |
| `INSTALLER_NO_ROOT` | boolean | `false`/not set | nothing | if set, root password is not set via the anaconda spoke (but, for now, will be set by chrooting into the installed system at the end of installation) |
| `GRUBADD` | string | not set | nothing | when set, append this string to kernel line in GRUB, after the `GRUB` string if that one is set too. This is never set by tests; instead it's provided as a way to e.g. run the normal tests with an `updates.img` to test some anaconda change (the scheduler CLI can help you use this feature) |
| `USER_LOGIN` | string | not set | should be used with `USER_PASSWORD` (unless `false`) | when set, user login is set to this value. If not set, default value `test` is used for console installs, no login is done for graphical installs. If set to `false`, no user login will be done |
| `USER_PASSWORD` | string | not set | should be used with `USER_LOGIN` | when set, user password is set to this value. If not set, default value `weakpassword` is used for console installs, no login is done for graphical installs |
| `TEST_UPDATES` | boolean | `false`/not set | set to indicate that this test checks updates.img loading, so we should check for the expected effect of the updates image used for this testing |
| `PREINSTALL` | string | not set | nothing | If set, specified module will be loaded before reboot and install; module supposed to be starting as rescue mode |
| `POSTINSTALL` | string | not set | nothing | If set, `tests/(value)_postinstall.pm` will be loaded after install, boot, login, and other postinstall tests
| `ANACONDA_STATIC` | string (IPv4 address) | not set | `ANACONDA_TEXT` | If set, will set up static networking using the chosen IP address during install |
| `POST_STATIC` | string (space-separated IPv4 address and hostname) | not set | nothing | If set, will set up static networking using the chosen IP address and hostname during early post-install |
| `NO_UEFI_POST` | boolean | `false`/not set | nothing | If set, `uefi_postinstall` test will not be loaded even if `UEFI` is set (can be useful for non-English tests to avoid `uefi_postinstall` running loadkeys) |
| `ISO` | contains filename of ISO that is used for booting. If `ISO_URL` is not set, file must exist in /var/lib/openqa/share/factory/iso. If `ISO_URL` is set, it will be downloaded to this name instead of its original name |
| `ADVISORY` | A Bodhi update ID. If set, the 'update testing' flow will be used: post-install tests will be run with the packages from the update, starting from the stable release base disk images |
| `KOJITASK` | A Koji task ID. If set, the modified 'update testing' flow for testing scratch builds will be used: post-install tests will be run with the packages from the update, starting from the stable release base disk images |
| `FLAVOR` | indicates what type of distribution is used. Three Pungi properties, joined with `-`: `variant`, `type`, and `format`. e.g.: `Server-dvd-iso`. Special value `universal` is used to schedule the group of tests that should be run once each per arch per compose, against the 'best' available ISO |
