Hi,

is it possible to disable PXE in all VMs in an Openstack environment? Apparently its ddos my neutron when a machine tries to boot from pxe and we needed it.

Many Thanks

UPDATE: The result of this looks like this:

Oct 11 12:06:30 controller01 dnsmasq-dhcp[8290]: DHCPDISCOVER(ns-6e497a53-77) fa:16:3e:2d:24:7d no address available

UPDATE:

dnsmasq is assigning the ip correct:

What then happens is an arp storm for the gateway. My router is answering the arp reply, but the vm keeps asking (~500 times/s) for the arp.

Still trying to get more information, but its very weird (since it worked before)
