I found the DAD will take 7 seconds
on my machine, and i cannot create a network which
use ipv6 now :( . Can we offer a way allow user to change this
timeout ? maybe add a configuration file option in
libvirtd.conf.
Could you please send the related records of your sysctl -a?
Max DAD timeout should be
rand() % net.ipv6.conf.default.router_solicitation_delay +
net.ipv6.conf.default.dad_transmits *
net.ipv6.neigh.default.retrans_time_ms
I wonder whether my calculations were faulty or it is your specific
configuration.
