qemu for windows fails to use multicast socket as netdev
My host OS is Windows 7 x64 SP1. I installed qemu for windows from https://qemu.weilnetz.de/w64/.The version is 2.10.1, qemu-w64-setup-20171006.exe. I run qemu with the following command:
qemu-system-x86_64.exe -net nic -net socket,mcast=234.5.5.5:6000 disk1.qcow2
It stopped with error:
bind: Unknown error
qemu-system-x86_64.exe: -net socket,mcast=234.5.5.5:6000: Device 'socket' could not be initialized
Using the -netdev option has the same problem:
qemu-system-x86_64.exe -netdev socket,id=hostnet0,mcast=234.5.5.5:6000 -device e1000,netdev=hostnet0 disk1.qcow2
I tried many versions from https://qemu.weilnetz.de/w64/, but none of them could work.
