euca-allocate-address failed

asked 2011-04-04 13:24:53 -0500

I installed Nova with script from https://github.com/dubsquared/OpenStack-NOVA-Installer-Script/raw/master/nova-CC- (https://github.com/dubsquared/OpenSta...) install-v1.1.sh When I try to run euca-allocate-address command it failed with following message: root@Moshe-U2:~# euca-allocate-address UnknownError: An unknown error has occurred. Please try your request again.

How can I resolve it?

In my configuration I use FlatManager network. Do I need to "euca-allocate-addres" to create public IP? Curently I have running instance, but I can't SSH or ping to it's IP My nova,conf --dhcpbridge_flagfile=/etc/nova/nova.conf --dhcpbridge=/usr/bin/nova-dhcpbridge --logdir=/var/log/nova --state_path=/var/lib/nova --verbose --s3_host=170.70.0.3 --rabbit_host=170.70.0.3 --cc_host=170.70.0.3 --ec2_url=http://170.70.0.3:8773/services/Cloud --fixed_range=10.0.0.0/12 --network_size=8 --FAKE_subdomain=ec2 --routing_source_ip=170.70.0.3 --verbose --sql_connection=mysql://root:moshe@170.70.0.3/nova --network_manager=nova.network.manager.FlatManager --libvirt_type=qemu

Did you create some floating IP addresses first? You need to run

nova-manage floating create my-hostname xxx.xxx.xxx.xxx/xx

before you can use euca-allocate-address.

Have a look at the last answer to this question, https://answers.launchpad.net/nova/+question/149013 (https://answers.launchpad.net/nova/+q...)

There's more info on floating IPs there.

I changed network manager to FlatDHCPManager and now it's working. I'm just wondering if somebody worked with FlatManager?

Thanks, Moshe

First you need to "create" public IPs with

nova-manage floating create my-hostname xxx.xxx.xxx.xxx/xx

keep in mind that those public IPs have to belong to you and be routable to your network.

Then you need to allocation them to yourself as a nova user.

euca-allocate-address xxx.xxx.xxx.xyy

Finally you associate them with an instance.

euca-associate-address -i i-1 xxx.xxx.xxx.xyy But if you can't ping or ssh the private IP address you're not going to get very far with a public IP address. Personally, I've never had much luck with FlatManager. I've only been able to ping and ssh to instances with FlatDHCPManager or VlanManager. You might want to try one of those network modes. Plus there's lots of help with that problem in the answershttps://answers.launchpad.net/nova/+questions?field.search_text=ping+ssh&field.sort=RELEVANCY&field.sort-empty-marker=1&field.actions.search=Search&field.language=en&field.language-empty-marker=1&field.status=OPEN&field.status=NEEDSINFO&field.status=ANSWERED&field.status=SOLVED&field.status-empty-marker=1already.

You might also want to have a look at the trunk documentation for Configuring Network on the Compute Nodehttp://docs.openstack.org/trunk/openstack-compute-admin/content/configuring-networking-on-the-compute-node.html. It's got a lot more info than what's in the official docs currently.
