I have a node running 30 xen vps. When I ping my node IP, it's okay, but when I ping the guest IPs, there's high packet loss. Even when I login to my node to ping guests, there're high packet loss.
I've checked iptables, there's no rule for this, because when I stop iptables, packet loss still happens.
I've tried reboot the server but still not solved, anyone has any idea?
