If DAD not finished in 5 seconds, user will get an unknown error like this:

Call virReportError to set an error.
Signed-off-by: Luyao Huang <lhuang@redhat.com> --- 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.
I haven't change them before, and they are: net.ipv6.conf.default.router_solicitation_delay = 1 net.ipv6.conf.default.dad_transmits = 1 net.ipv6.neigh.default.retrans_time_ms = 1000 Thanks your quick reply. Luyao
