I'm re-sending a patch series here collected by @dramforever, see https://gitlab.com/qemu-project/qemu/-/issues/3065#note_2969046870 https://github.com/qemu/qemu/compare/v10.1.2...dramforever:add-termios2
With glibc-2.42 several architectures switch to termios2 for default terminal control, that however so far fails badly at the moment since the ioctls are unsupported. This series fixes that. While I have not authored any of this, I have reviewed it and have tested it extensively on alpha and (o32 be) mips. In both cases a Gentoo installation stage successfully rebuilt itself in a systemd-nspawn. Please consider for inclusion. Closes: https://gitlab.com/qemu-project/qemu/-/issues/3065
