Hi Experts,

I am new to vagrant/coreos and facing some problem. I am not able to resolve this issue from last 4-5 days. I am using Ubuntu 14.04 and on which I installed vagrant 1.6.2 and virtual box 4.2 and I am trying to get coreos cluster up and running but I am getting this error "Warning: Connection timeout. Retrying..." when I try to do vagrant up/vagrant ssh. You will get all the details below

# VirtualBox, so should only be used in debugging situations

# Enable port forwarding of Docker TCP socket

# Set to the TCP port you want exposed on the *host* machine, default is 2375

# If 2375 is used, Vagrant will auto-increment (e.g. in the case of $num_instances > 1)

# You can then use the docker tool locally by setting the following env var:

# export DOCKER_HOST='tcp://127.0.0.1:2375'

#$expose_docker_tcp=2375

Hello,

I saw that the coreos vm did start fine..

so, can go more simple and tell what is not working?

Hi Aguiera,

Thanks of the reply and sorry for replying you late.

The problem was the coreos VM's did start but I am not able to login/ssh to that VM's. As you can see below I am getting "Warning: Connection timeout. Retrying..." error marked in bold. So can you tell me how should I troubleshoot this? I think almost all the details I have pasted in my first post. If you need anything else just let me know

Manishr, please try adding config.ssh.insert_key = false to your Vagrantfile in the vm.configure block. If you are using Vagrant 1.7.x it will replace the default insecure key, and unless Vagrant is correctly accounting for that when going to SSH into the VMs, it will be using the wrong key.

From http://docs.vagrantup.com/v2/vagrantfile/ssh_settings.html

Hi Dragonr,

I am using vagrant 1.6.2. Let me try your suggestion and get back to you with the answer.
