### observation The fullstack test of os-autoinst fails under Tumbleweed because `eth0` (within the SUT) does not get an IP address assigned automatically anymore. Likely a change within QEMU causes this. As a workaround the following PR has been merged: https://github.com/os-autoinst/os-autoinst/pull/1728/files That means assigning an IP manually works and to reproduce the issue via os-autoinst's fullstack test one needs to revert 3cd3e5fe076ad4c1ee55ace70eade03d1f1f9bc8. (Btw, the workaround should likely have assigned the IP 10.0.2.15 because 10.0.2.2 is actually the Gateway.) The problem is not limited to the TinyCore system, it also happens with openSUSE. E.g. when cloning a test with the `online_repos` module (like https://openqa.opensuse.org/tests/1849850) it becomes quite apparent that the IP address is not assigned:  (The referenced test does *not* fail on the production instance because on production we're using Leap which doesn't seem to be affected.) ### suggestions * Check for changes within Tumbleweed's QEMU package * Check for changes of the QEMU invocation produced by os-autoinst * Likely a DHCP problem (with the DHCP server QEMU is supposed to provide?) * Read https://wiki.qemu.org/Documentation/Networking ### further notes * So far I've been testing this with `qemu-6.0.0-27.1.x86_64` as provided by Tumbleweed. * When just starting QEMU via `qemu-system-x86_64 -m 1024 -accel kvm -netdev user,id=qanet0 -device virtio-net,netdev=qanet0,mac=52:54:00:12:34:56` than iPXE shows that the IP address is assigned correctly.
