Re: wrong IP given by flat network dhcp

 

Well, I changed /etc/network/interfaces accordingly (see below) and didn't make any change in nova.conf, but the problem still remains. New VM are given IPs from 10.18.9.2 (and not 10.18.9.33). What else can I check?


$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
#iface eth0 inet dhcp
iface eth0 inet static
address 172.22.22.1
gateway 172.22.0.1
netmask 255.255.0.0
network 172.22.0.0
broadcast 172.22.255.255

auto eth1
iface eth1 inet static
address 10.18.9.1
netmask 255.255.255.224
network 10.18.9.0
broadcast 10.18.9.31

Here's the output of ifconfig:

You have to create your network with the same range
it looks like you created with something like 10.18.9.0/24

Hello,

I installed Essex on Ubuntu 12.04 Server, and I had a problem with VM IP.

The IP given to the VM (10.18.9.2) isn't in the fixed_range. Here's a portion of nova.conf:

# cat /etc/nova/nova.conf
[...]
--network_manager=nova.network.manager.FlatDHCPManager
--public_interface=eth0
--flat_interface=eth1
--flat_network_bridge=br100
--fixed_range=10.18.9.32/27
--floating_range=172.22.22.32/27
--network_size=32
--flat_network_dhcp_start=10.18.9.33

and here's the host network config:

# cat /etc/network/interfaces
auto eth0
iface eth0 inet static
address 172.22.22.1
gateway 172.22.0.1
netmask 255.255.0.0
network 172.22.0.0
broadcast 172.22.255.255

auto eth1
iface eth1 inet static
address 10.18.9.1
netmask 255.255.0.0
network 10.18.0.0
broadcast 10.18.255.255

Then I deployed another VM, and I was given IP 10.18.9.3. Here's an excerpt of /var/log/nova/nova-network.log when I deployed this machine:

what am I doing wrong?
