Control: tag -1 + unreproducible Hm.
I can't reproduce this issue. I did a rebuild of qemu on bookworm though, but it is really unlikely current unstable is different in this context. When you said it worked before, how did it work, - were there some messages on the tty or some other indication of its "working" state? For me, there's basically no difference between 8.2.* and 9.0.2-4, both works the same way - be it -netdev bridge or -netdev tap. With or without qemu_bridge_helper. # qemu-system-x86_64 -netdev tap,id=n1 -display none -monitor stdio QEMU 9.0.2 monitor - type 'help' for more information qemu-system-x86_64: warning: netdev n1 has no peer (qemu) info version 9.0.2Debian 1:9.0.2+ds-4~bpo12+1 (qemu) q (hmm, apparently it needs a space before Debian in version, but it is a different issue). Thanks, /mjt
