instance failed to spwan

Asked by yang on 2013-03-16

hi all,
i install the openstack (Folsom) with ubuntu12.04 desktop. i use the basic install guide from the offical website.
i use three nodes:
Controller node: eth0: (External network), eth1: network)
Network node: eth0: (External network), eth1: network) eth2: (Data network)
Compute node: eth0: network) eth1: (Data network)

when i finish installing, i am confused, because the Network node can not get on the internet...

when i log on the dashboard and launch the instance, it failed. and i go to see the log in the Compute node, from the nova-compute.log i see ERROR:
instance failed to spwan
HTTPInternalServerError: HTTPInternalServerError (HTTP 500)

how can i solve the problem? can someone help me ?

Their seems to be two issues,

1) network node can't get to Internet
2) problem starting a instance

1) can you confirm that you access the Internet fron the network nove over
2) are you saying the fron the network node you can not ping say google at
3) can you ping google from the controller node
4) can you post the compute log with the error, if log debug was turned off, turn it on in config and start instance and post logs.

You must get the network node to ping the Internet, this should be possible.

Can you help with this problem?
