This patch series attempts to improve the reliability of several of the VM test targets. In particular, both CentOS 8 tests are non-functional because CentOS 8 was EOL at the beginning of this calendar year, with repositories and mirrors going offline.
Notably, I also remove the ubuntu.i386 test because we no longer support Ubuntu 18.04 nor do we have explicit need of an i386 build test. After this series, I am able to successfully run every VM target on an x86_64 host, except: - ubuntu.aarch64: Hangs often during testing, see below. - centos.aarch64: Hangs often during testing, see below. - haiku.x86_64: Build failures not addressed by this series, see https://lists.gnu.org/archive/html/qemu-devel/2022-06/msg02103.html The unit tests that I see fail most often are: - qom-test: ENOMEM with default config and many cores - test-hmp: ENOMEM with default config and many cores - virtio-net-failover: Seems to like to hang on openbsd - migration-test: Tends to hang under aarch64 tcg Increasing the default memory (patch 10) has seemingly helped both reliability *and* reduced race conditions quite a bit, both on my 12-thread intel laptop and on my 32-thread AMD 5950x desktop. Due to how long it takes to run these tests, though, I can't claim perfect reliability. The flakiness of virtio-net-failover and migration-test is something that probably still needs to be addressed, but it's outside of my expertise and time budget at present to pursue it. Future work (next version? next series?); - Try to get centos.aarch64 working reliably under TCG - Upgrade ubuntu.aarch64 to 20.04 after fixing centos.aarch64 - Fix the Haiku build test, if possible. - Ensure I can reliably run and pass "make vm-build-all". (Remove VMs from this recipe if necessary.)
