Future directions for the Beaker test harness
by Nick Coghlan 12 Mar '18

12 Mar '18

A few weeks back, Amit put together a proof of concept for running the test harness in a container, rather than directly on the host (http://gerrit.beaker-project.org/#/c/3199) That proof of concept relies on restraint, the new reference harness, that is intended to eventually replace beah (https://beaker-project.org/dev/proposals/reference-harness.html) At the same time, I don't think restraint is currently getting the level of review and testing that it needs to mature into a plausible replacement for beah as the default harness. I think Amit's proposed patch provides a possible way forward: 1. Accept the initial approach where restraint is the *only* supported harness when running inside a container. Specifying both "contained_harness" and "harness" as ks_meta variables should be an error at this point (side note: 'harness' should also be documented along with all the other ks_meta variables, with a link to https://beaker-project.org/docs/alternative-harnesses/) 2. Recommend publishing both beah *and* restraint in the harness repos for Beaker installations. This will not only make restraint available for container based testing, but also make it readily available via "harness=restraint" for normal testing, without needing to add a custom repo definition. 3. Once we have container based testing working reliably with restraint, drop the restriction against using alternative harnesses in containers. The priority at the moment though is to get something working that can run on an Atomic Host, and still provide a relatively normal execution environment for the executed tasks. Supporting alternative harnesses *inside* containers is a nice-to-have that can wait until later - by flatly disallowing it, we ensure we don't have to spend any time working on container related issues that don't impact restraint. For the initial iteration, we can also ignore the question of choosing the base image used to run the harness, as well as being able to start and stop other containers on the host. I've filed an RFE for 0.18 on that basis: https://bugzilla.redhat.com/show_bug.cgi?id=1131388 As part of this, we may also want to move restraint from Bill's personal account on GitHub to the main Beaker project account, but I don't think that's particularly urgent at this point.

Beaker inventory: smolt & lshw comparison
by Amit Saha 24 Apr '15

24 Apr '15

Hi all, As part of the migration to "lshw" for beaker's inventory task, I ran a comparison of the "smolt" based tasks with the "lshw" based task. The "raw" data is available in the "comparison.html" file under each arch sub-directory at: https://amitksaha.fedorapeople.org/beaker-inventory-comparison/comparison_d… Here are the summarized differences: ** i686/AMD/athlon (32-bit system) CPU flags ========= * lshw categorises "fpu_exception" as a CPU flag, adds "wp" as cpu flag too. (This is because we assume all the stuff lshw lists as CPU capabilities, we consider them flags) Others ====== * USBID retrieved by lshw with repetition, smolt didn't retrieve any * Same PCIID retrieved by lshw, however there is repetition of a device (for PCIID as well) * lshw is not able to detect the system model (same as smolt) * lshw sets arch to i686 instead of i386 by smolt * lshw fails to get the system vendor (same as smolt) * lshw fails to get the FORMFACTOR * CPUVENDOR obtained by smolt is AuthenticAMD, lshw sets it to "Advanced Micro Devices [AMD]" ** ia64 CPU flags ========= * No CPU flags retrieved by lshw Others ====== * Bulk of the USB IDs retrieved are 0000:0000s * lshw is not able to detect the system model * CPUFAMILY is reported by smolt as 1, by lshw as 2 * lshw fails to get the system vendor * lshw fails to get the FORMFACTOR, same as smolt * CPUVENDOR obtained by smolt is genuineintel, lshw sets it to "Intel corp." * CPU stepping obtained by smolt is 0, whereas it is None by lshw * PCIIDS retrieved by lshw contain one missing PCIID and a number of repetitions * Memory reported by smolt is 7863 MB, 8192 by smolt. (**Needs more investigation**) ** ppc64/Power 6 CPU flags ========= * No CPU flags retrieved by either Others ====== * USBID retrieved by lshw, none by smolt, contains one repetition * lshw is not able to detect the system model, same as smolt * lshw fails to get the system vendor * lshw reports a repeating PCIID (same as smolt) ** ppc64/Power 7 CPU flags ========= * CPU flags retrieved by lshw as "performance-monitor" Others ====== * No USB devices reported by either * lshw is not able to detect the system model, same as smolt * lshw fails to get the system vendor * lshw and smolt both doesn't report any PCIIDs ** s390 CPU flags ========= * CPU flags reported by lshw are each duplicated Others ====== * No USBIDs retrieved by lshw, none by smolt * lshw is not able to detect the system model, same as smolt * lshw fails to get the system vendor, same as smolt * lshw reports a repeating PCIID (same as smolt) * Memory is reported as 2001 MB by both, system has 2048 MB ** x86_64/amd CPU flags ========= * lshw uses x86-64 in place of lm * lshw categorises "fpu_exception" and "cpufreq" as a CPU flags (This is because we assume all the stuff lshw lists as CPU capabilities, we consider them flags) Others ====== * More USBID retrieved by lshw, however there is repetition of a device (for PCIID as well) * lshw is not able to detect the system model * lshw sets VIRT_IOMMU to False, whereas smolt has it to True * lshw sets arch to x86-64 instead of x86_64 * smolt gets CPUMODEL as " AMD Eng Sample, 1S256146U8K54_35/25/20_2/8 ", lshw gets it as "Opteron" * lshw fails to get the system vendor * lshw fails to get the FORMFACTOR * CPUVENDOR obtained by smolt is AuthenticAMD, lshw sets it to "Advanced Micro Devices [AMD]" * smolt gets 3811 MB of memory, lshw gets None on an 3919 MB system (**Needs more investigation**) ** x86_64/intel CPU flags ========= * lshw uses x86-64 in place of lm * lshw categorises "fpu_exception" and "cpufreq" as a CPU flags (This is because we assume all the stuff lshw lists as CPU capabilities, we consider them flags) Others ====== * More USBID retrieved by lshw, however there is repetition of a device * lshw is not able to detect the system model * lshw sets arch to x86-64 instead of x86_64 * smolt gets CPUMODEL as "Intel(R) Xeon(TM) CPU 3.60GHz", lshw gets it as "Xeon" * lshw fails to get the system vendor * CPUVENDOR/vendor obtained by smolt is GenuineIntel, lshw sets it to Intel Corp. * lshw gets 4096 MB of memory correctly ** x86_64/kvm guest CPU flags ========= * lshw uses x86-64 in place of lm * lshw categorises "fpu_exception" as a CPU flag (This is because we assume all the stuff lshw lists as CPU capabilities, we consider them flags) Others ====== * USBID retrieved by lshw, none by smolt * lshw is not able to detect the system model * lshw sets arch to x86-64 instead of x86_64 * lshw fails to get the system vendor * CPUVENDOR/vendor obtained by smolt is GenuineIntel, lshw sets it to Intel Corp. * lshw fails finds one device less (PCIID) * lshw gets 2048 MB of memory correctly ** Common to all archs For all the architectures, the devices list returned by the lshw task is fewer than those returned by smolt. The devices need to be individually compared to come up with a more accurate answer. PS: arm 32-bit and 64-bit comparison: Not possible, since we cannot run any smolt supported distro on these. The next plan of action is to fix the issues that we have found above - either in "beaker-system-scan" or "lshw" itself. Best, Amit. -- Amit Saha SED, Hosted & Shared Services Red Hat, Inc.

Changing status ordering in Beaker 21
by Dan Callaghan 24 Apr '15

24 Apr '15

In the next Beaker major release (21.0) we are planning to make a change to the way Beaker computes the overall status for jobs, recipe sets, and recipes. Currently if some tasks in a recipe are Completed but others are Aborted or Cancelled, the overall recipe status will be Completed. This is surprising and (arguably) less useful because it obscures the fact that the whole recipe did not really complete. Similarly, if some recipes in a recipe set or job are Completed but others are Aborted or Cancelled, the overall status will be Completed right now. In Beaker 21 we will change the status calculation so that if any task is Aborted or Cancelled, the entire recipe is Aborted or Cancelled, and thus the recipe set and job is Aborted or Cancelled too. If you see any issues with this change in behaviour please bring it up here and we can discuss. -- Dan Callaghan <dcallagh(a)redhat.com> Software Engineer, Products & Technologies Operations Red Hat, Inc.

Beaker 20.0 released
by Dan Callaghan 21 Apr '15

21 Apr '15

On behalf of the Beaker development team, I'm pleased to announce that Beaker 20.0 is now available from the Beaker web site [1]. Thanks to everyone who contributed patches and bug reports for this release. In Beaker 20 we have implemented the "system pools" feature. On top of that, it is now also possible to set a system to use the access policy defined on a pool. The aim is to make it easy to apply the same access policy across a large number of systems. The other significant feature in Beaker 20 is support for configuring the network boot loader on a per-recipe basis. This lets Beaker automatically select a supported boot loader depending on the distro being provisioned, and for users to select a different boot loader in their recipes. There are also plenty of other minor enhancements and fixes. As usual, the release notes [2] have all the details. The detailed list of all changes made since Beaker 19.3 is also available [3].
