Indeed. I'm able to reproduce and working on a fix as we speak.
The problem is that our test assumes that if there is an interface with 
IPv4 address (as returned by getifaddrs()) then getaddrinfo() of an IPv4 
address succeeds. We've seen with IPv6 that it is not true - that's why 
virNetSocketCheckProtocols() does explicit getaddrinfo() for an IPv6 
address. We need to do the same for IPv4.
