The QEMU project is currently considering to move its bug tracking to another system. For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or please mark it as "Fix Released" if the problem has been solved with a newer version of QEMU already. Thank you and sorry for the inconvenience. ** Changed in: qemu Status: New => Incomplete -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1861884 Title: qemu socket multicast not working Status in QEMU: Incomplete Bug description: Running two qemu vms on the same socket multicast address: qemu-system-x86_64 -m 2048 -smp 2 -serial mon:stdio -display none -vga none -nodefaults -accel hax -netdev user,id=mynet0 -device virtio-net-pci,netdev=mynet0 -netdev socket,id=vlan,mcast=239.192.0.1:1235 -device virtio-net-pci,netdev=vlan -device virtio-rng-pci -drive file=worker.qcow2,if=virtio -drive file=cloud-init.iso,format=raw,if=virtio The two machines have a static ip on the socket network interface, 192.168.100.11 and 192.168.100.12, but are unable to reach each other.
