Hi community, I need your help ,tips, advices. *> Environment <* I have deployed Openstack "Stein" using the latest kolla-ansible on the following deployment topology: 1) OS Controller running as VM on a "cloud" location 2) OS Compute running on a baremetal server remotely (wrt OS Controller) location 3) Network node running on the Compute host As per the above info, Controller and compute run on two different networks. Kolla-Ansible is not really designed for such scenario but after manipulating the globals.yml and the inventory files (basically I had to move node specific network settings from the globals to the inventory file), eventually the deployment works fine. *> Problem <* I have no specific issue working with this deployment except the following: "SSH connection to the VM is quite slow". It takes around 20 seconds for me to log into the VM (Ubuntu, CentOS, whatever). *> Observations <* - Except for the slowness during the SSH login, I don't have any further specific issue working with this envirorment - With the Network on the Compute I can turn the OS controller off with no impact on the VM. Still the connection is slow - I tried different type of images (Ubuntu, CentOS, Windows) always with the same result. - SSH connection is slow even if I try to login into the VM within the IP Namespace
From the ssh -vvv, I can see that the authentication gets stuck here:
debug1: Authentication succeeded (publickey). Authenticated to ***** debug1: channel 0: new [client-session] debug3: ssh_session2_open: channel_new: 0 debug2: channel 0: send open debug3: send packet: type 90 debug1: Requesting no-more-sessions@openssh.com debug3: send packet: type 80 debug1: Entering interactive session. debug1: pledge: network
10 to 15 seconds later

Any suggestion? Many thanks /Giuseppe
