I have an OpenStack Kilo multinode setup witha controller, network and 2 compute nodes. I am able to boot VM instances and they are going to active state.

Now I want to SSH the VM's created and install some application on it. My doubit is how to SSH the VM's as I don't have a dashboard and therefore don't have a console for the VM's created. So I need to get the consoles for the VM's created and install ssh client on it.

Kindly provide some information regarding this.

you mean to say that you want syntax or any troubleshooting assistance while doing it.

anyway following is the command. first of all launch vm with your choice of image which you done already. add rules to it. like,

nova secgroup-add-rule default icmp -1 -1
nova secgroup-add-rule default tcp 22 22

for cirros instance.


for ubuntu instance..

1. nova keypair-add OSKEY > OSKEY.priv (where OSKEY is the one you generated from ssh-keygen command)
2. chmod 600 OSKEY
3. now launch the instance with the OSKEY as the key
4. ssh -i OSKEY.priv ubuntu@floatingIP

hope that helps

Create a VM with all required dependencies like SSH + apps in Virtual Box with .vmdk as extension, then upload this vm image into glance and create new VMs out of it. Then associate floating IPs and ssh into them.
