OpenStack Compute (nova)

euca-allocate-address failed

Asked by KiRaDo

I created some instances:

$ euca-describe-instances
RESERVATION r-r13s4ps0 project1 default
INSTANCE i-00000001 ami-357d27f2 10.0.0.3 10.0.0.3 running key01 (project1, ubuntu2) 0 m1.tiny 2011-04-18T01:38:27Z nova
RESERVATION r-c9x29yyp project1 default
INSTANCE i-00000003 ami-357d27f2 10.0.0.5 10.0.0.5 running key01 (project1, ubuntu2) 0 m1.tiny 2011-04-18T02:33:29Z nova
RESERVATION r-o00kdp76 project1 default
INSTANCE i-00000002 ami-5369bcf3 10.0.0.4 10.0.0.4 running key01 (project1, ubuntu2) 0 m1.tiny 2011-04-18T02:08:06Z nova

then i created floating IP address

$ sudo nova-manage floating create cloud1 10.2.14.0/24

$ sudo nova-manage floating list
cloud1 10.2.14.0 None
cloud1 10.2.14.1 None
cloud1 10.2.14.2 None
cloud1 10.2.14.3 None
cloud1 10.2.14.4 None
cloud1 10.2.14.5 None
..............
cloud1 10.2.14.253 None
cloud1 10.2.14.254 None
cloud1 10.2.14.255 None

However, when I try to run euca-allocate-address command it failed with following message:
$ euca-allocate-address 10.2.14.206
UnknownError: An unknown error has occurred. Please try your request again.

How can I resolve it?

try typing hostname on your network host
the hostname when you create floating ips has to be == to whatever hostname returns (probably ubuntu2 judging by the output of your describe)
also when you euca-allocate-address you don't specify the ip that you want.

Thanks Vish,
I only have a host that running api, network, compute. Hostname is ubuntu2

How can I do to use euca-allocate-address command?

Best Vish Ishaya (vishvananda) said : 		#3

sudo nova-manage floating delete cloud1 10.2.14.0/24
sudo nova-manage floating create ubuntu2 10.2.14.0/24
euca-allocate-address

It will display one of the addresses from the pool and you can associate it with an instance
