I'm doing a Folsom deployment with FlatDHCP (not multihost). When I try to boot a quantal image, the instance doesn't pick up the DHCP lease. I've confirmed that dnsmasq is sending out the DHCPOFFER, and I can see by tcpdump on the compute host that the DHCP packets are making it to the vnet0 interface.
Note that I tried adding this iptables rule as mentioned here < https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/issues/14>, but that didn't resolve it. iptables -D POSTROUTING -t mangle -p udp --dport 68 -j CHECKSUM --checksum-fill However, the problem goes away if I change this setting on the compute hosts in /etc/nova/nova.conf libvirt_use_virtio_for_bridges=true to: libvirt_use_virtio_for_bridges=false Anybody know what would cause this? I'm on Ubuntu 12.04 with the cloud-archive packages, with KVM as the hypervisor Lorin -- Lorin Hochstein Lead Architect - Cloud Services Nimbis Services, Inc. www.nimbisservices.com
