Observation¶

Originally reported by pvorel relating to http://quasar.suse.cz/tests/6860#

It appears that QEMU 6.0 requires explicit memory assignment to NUMA nodes using -numa node,mem=... command line arguments. OpenQA jobs with QEMU_NUMA=1 currently fail to start on Tumbleweed because os-autoinst omits the mem option, which leads to the following error:

Acceptance criteria¶

• AC1: os-autoinst continues to start for qemu >= 6.0 and QEMU_NUMA=1
• AC2: os-autoinst jobs still work fine on qemu < 6.0 regardless of QEMU_NUMA setting
