HI
We setup a cloud using Static mode and system mode.It worked fine.But the problem now is with the managed mode
Our LAN setup is in 192.168.31.0 and 192.168.39.0.So for the cloud testbed we chose the ip as 192.168.61.1
In the previous case we registered our cloud using this ip 192.168.61.1.So the frontend worked fine as http;//192.168.61.1:8773
Since we needed an unused network range of ip ,we chose 172.16.1.0 as our subnet and configured the eucalyptus.conf file. and changed the frond end ip of the cluster also to 172.16.1.1.I downloaded the credentials for this ip and sourced the eucarc file.But still i get the following error

The nodes are getting listed using euca_conf but the availability zone verbose shows empty
If i check the ifconfig -a in front end the eth0 value is now

eth0 Link encap:Ethernet HWaddr 00:21:5a:d3:ec:e2
inet addr:169.254.169.254 Bcast:0.0.0.0 Mask:255.255.255.255

I donot understand why the ip address of eth0 changes from 172.16.1.1 to 169.254.169.254

Following are my cloud setup details
CLC/CC in one system with ip 172.16.1.1
Nodes in 2 systems with ip 172.16.1.2 and 172.16.1.3

Frontend eucalyptus.conf;

eucabr10 8000.000000000000 no

Status of Xend and libvirt is also verified and they are running
