deltacloud-server with ec2
Hello,
I hope you can help me :-)
i'm running the deltacloud-server on localhost. With this one i want to
connect to a ec2 server.
So i run deltacloudd -i ec2 -r ip -p3001
But i get a RuntimeError
eventmachine.rb:572: in 'start_tcp_server': no acceptor (RuntimeError)
Do i have to install the seltacloud-server on every ec2 server? Or must
i install sth on my ec2 server?
I hope you can give me an answer soon.
Best regards
Stefan Duesing

For a person who knows how a web server works and starting the DeltaCloud API server is equivalent to starting a web server, it is a fine message.
For a person who just wants to operate their remote VMs, it can be confusing.
If the -r option was hidden somewhere in an advanced section, fine, but it's published in the help option of the DeltaCloud server, so I think its description should be directed at DeltaCloud users instead of web server operators.
+1 on the improvement of the error message, but it would probably not have helped in the OP's case.

I think the help text is correct (and it's exactly what thin says for
the equivalent option)
It seems to me the problem is in the error message we and thin produce:
'no acceptor' seems to be the standard error message when _anything_
with binding to the IP address goes wrong - you get this also if you
start the server twice. It would be great if we could get something
clearer like 'cannot bind to port $host:$port' for those cases.

Hi all,
Stefan found me on irc and we resolved the issue:
The -r is to specify the local nic's ip address the DeltaCloud server will be running on, not the public ip address of the cloud provider or the VM instance you want to work with.
-r, --hostname HOSTNAME Bind to HOST address (default: localhost)
Can we improve the description?
Something like:
-r, --hostname HOSTNAME Run Deltacloud server on network card with HOST address (default: localhost)
