Huh? Oh, I see you can read the sentence two ways: (1) specifically listen on ipv6 only, if the machine actually has ipv6 connectivity (2) specifically listen on ipv6, only if the machine actually has ipv6 connectivity I mean (2), i.e. do not create a ipv6 socket if the machine has no ipv6 connectivity. When creating a ipv6 socket IPV6_ONLY should be clear by default indeed, so both ipv4 and ipv6 will work. cheers, Gerd -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
