<div dir="ltr">The vm should not have a routing table entry for <a href="http://169.254.0.0/16" target="_blank" style="font-family:arial,sans-serif;font-size:12.800000190734863px">169.254.0.0/16</a> if it does i'm not sure how it got there unless it was added by something other than dhcp. It seems like that is your problem as the vm is arping directly for that address rather than the default gw. </div>
