We've had test failures on systems with the ip6tables packet filter
blocking IPv6 multicast packets but otherwise I can't think of any issues.
In this case the interface is virbr0 so I assume this is a virtual
environment. I think this may need going through the libvirt
configuration as I assume the issue is that IPv4 multicast packets
aren't being forwarded.
