Both uses of this function are in this patch (I didn't realize that when
reviewing v1).
We can rename it to virSocketAddrNumericFamily and do
if (virSocketAddrNumericFamily(listenAddress) == AF_INET6), removing the need
for a temporary variable.

In qemuMigrationPrepareAny, we have:
if (encloseAddress)
incFormat = "%s:[%s]:%d";
else
incFormat = "%s:%s:%d";
if (virAsprintf(&migrateFrom, incFormat,
protocol, listenAddress, port) < 0)
goto cleanup;
Using the same pattern here as well would make it more readable.
