Title:
  qemu socket multicast not working

Status in QEMU:
  Expired

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.

  Result when using ping command

    PING 192.168.100.11 (192.168.100.11) 56(84) bytes of data.
    From 192.168.100.12 icmp_seq=1 Destination Host Unreachable
    From 192.168.100.12 icmp_seq=2 Destination Host Unreachable
    From 192.168.100.12 icmp_seq=3 Destination Host Unreachable

  Is there additional configuration necessary on macos? Does this only
  work on Linux? Is there additional configuration required inside of
  the guest OS?

  guest OS: Debian 10 (Buster)
  host OS: macOS 10.15.2
  qemu: 4.2.0
