6000 isn't really a valid parameter for network_size. It should be a power of two. Also, you need to specify the same network size when creating the network using nova-manage.

Question #161446 on OpenStack Compute (nova) changed:

Davor Cubranic posted a new comment: Vish, thank you! Once I set "flat_network_dhcp_start" and restarted nova-network, it all works fine.

Interestingly, I do have an extra dnsmasq running that's listening on That appears to be run by libvirt, and is not the cause of my errors so I left it running.

Now, what I don't understand is this: the docs say the default value for flat_network_dhcp_start is, and this is what showed up in OpenStack's dnsmasq process's parameters. My VMs are assigned addresses starting with, and once I set that in nova.conf as the value of flat_network_dhcp_start, everything startd working. But, I already had "network_size" set to 6000, so even if the range dnsmasq was using started at, why was outside it?
