Hi,

I was using RDO to install my OpenStack cluster on CentOS6.4, the network
is using nova-network, after deploy one instance, the instance can get
private IP successfully but I cannot ping the VM instance with its IP
address.

[root at db03b04 ~(keystone_admin)]# nova list
+--------------------------------------+------+--------+------------+-------------+--------------------------+
| ID                                   | Name | Status | Task State | Power
State | Networks                 |
+--------------------------------------+------+--------+------------+-------------+--------------------------+
| 3b6303db-0895-4643-85b7-9c3708f79c25 | vm4  | ACTIVE | None       |
Running     | novanetwork=192.168.32.3 |
+--------------------------------------+------+--------+------------+-------------+--------------------------+
[root at db03b04 ~(keystone_admin)]# ping 192.168.32.3
PING 192.168.32.3 (192.168.32.3) 56(84) bytes of data.

Check VM console log, it says following:

Starting logging: OK
Initializing random number generator... done.
Starting network...
udhcpc (v1.18.5) started
Sending discover...

No lease, failing

wget: can't connect to remote host (169.254.169.254): Network is unreachable
cloud-setup: failed 1/30: up 10.38. request failed

I googled this issue and found many people are asking same question, but I
did not get a clear answer for this. Does anyone who has some experience on
this?

BTW: I was using the image from
https://launchpad.net/cirros/trunk/0.3.0/+download/cirros-0.3.0-x86_64-disk.img-O
cirros.img

Thanks,

Jay
