Three problems with our_addr: - It's determined only once when qemu starts, but the address can change (just like the DNS configuration can). - It's supposed to be the IP address of a host network interface, but there's no guarantee that gethostbyname(gethostname()) actually does that: the host might be a laptop that has only a loopback interface up, or the hostname might be localhost.localdomain, etc. - It's useless at best: get_dns_addr() calls it, there's no reason to send DNS requests to a different IP address if you're running a DNS server on the host and resolv.conf points to 127.0.0.1. These problems are easily solved by removing the code. Signed-off-by: Ed Swierk <eswierk@aristanetworks.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
