I used the dashboard to create a router, a network, then created a Ubuntu 14.04 VM. I have tried creating the VM with "Create keypair" and also with "Import keypair" and pasting the public key. I associated a floating IP and I can ping the IP from a DOS cmd prompt. When I try to access the VM using PuTTY I get the "Server refused our key" error. I checked the log file in the Horizon dashboard and I see cloud-init and sshd are started. With PuTTY I get "PuTTY Fatal Error" with "Disconnected: No supported authentication methods available (server sent: publickey)"

I must be missing something very basic during my VM creation. What do I need to do to be able to access my VM?

Here is the log file from Horizon:

 * Starting NTP server ntpd       [80G [74G[ OK ]

Does the vm get metadata from openstack?

Also when you created the ubuntu vm did u select the keypair that you created from the access and security tab?

If so then when you connect with putty you must take the .pem keyfile and transform it using puttygen into a putty recognisible format (.ppk). Then you load it into putty and connect to the ubuntu vm. The default username is ubuntu.

If this doesn't work then the metadata service isn't working. Check if the service is running and view the logs .

In my case, where i have 2 controller nodes and 3 compute nodes using neutron dvr, if i created a vm it wouldnt fetch the metadata from the controller nodes untill i enabled the metadata service on the compute nodes aswell.

Thank you. I don't see any metadata service, no cloud-init, and no sshd. My log file shows only a question mark "?" I restarted the instance and still see only a "?" in the log file.

I am contacting our Openstack support team. I can ping the Public IP from my Windows DOS prompt. I am using PuTTY on my Windows 7, 64-bit image. I copied the public key directly from Puttygen and pasted it into the "Import keypair" option in the Horizon dashboard. I used a PuTTY profile that I tested that uses the same keypair and renamed it and used the new VM's public IP (which I can ping). Now I get the PuTTY prompt for a password:

"username@ip_address's password:"

I will contact our support team and ask them to check on their side

UPDATE I used the dashboard to create a new keypair, used Puttygen to convert it to a .ppk then I used the nova command line to create a VM and was able to successfully login. I am spinning up a new VM in the dashboard and using the new key to see if my problem was my existing key or if it is the Horizon Dashboard.

It turns out in this particular zone I have to create a key pair or import a key pair then ssh in as "root". The ID I used to create the VM and the keypair would not work.I had to use the nova command line to create the VM. For some reason any VM I spun up from the Dashboard just would not work.
