At first I assumed this was due to missing kernel support for multicast, hence why I submitted https://github.com/gentoo/gentoo/pull/34380 . I should have tested this without making assumptions, because that does not seem to be the cause. This instead looks like a network-sandbox issue. # starting QEMU: exec ./qemu-system-x86_64 -qtest unix:/var/tmp/portage/app-emulation/qemu-8.0.5/temp/qtest-3016.sock -qtest-log /dev/null -chardev socket,path=/var/tmp/portage/app-emulation/qemu-8.0.5/temp/qtest-3016.qmp,id=char0 -mon chardev=char0,mode=control -display none -nodefaults -M none -netdev dgram,id=st0,remote.type=inet,remote.host=230.0.0.1,remote.port=1234 -accel qtest ----------------------------------- stderr ----------------------------------- qemu-system-x86_64: -netdev dgram,id=st0,remote.type=inet,remote.host=230.0.0.1,remote.port=1234: can't add socket to multicast group 230.0.0.1: No such device (test program exited with status code -13) The only reference I could find was this issue https://github.com/cockpit-project/cockpit/issues/12782 and corresponding fix https://github.com/cockpit-project/bots/pull/3717 . But when I tried to implement that in the qemu test, it bails out like: qemu-system-aarch64: -netdev dgram,id=st0,localaddr=127.0.0.1,remote.type=inet,remote.host=230.0.0.1,remote.port=1234: Parameter 'localaddr' is unexpected Sample log is from amd64, but this reproduces on all arches. Reproducible: Always
