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
