Open Stack

When you create the user, not sure how your installation was performed but your user should always have a home dir. Your account should be able to do use the ssh-copy-id to copy the key from one server to the other. By default the account may not have a valid shell, I would also check on that.

Yes key is now owned by nova user in default dir /var/lib/nova/.ssh
This dir was not present I mean nova user was not present earlier. 
I will check the pemissions also test and get back.

You should always do su – nova and not su nova. I would check the permissions, do you have an ssh key, is it owned by nova user, after that you need to copy that key between the compute.

Hello Remo and All, 

When I upgraded my libvirt and kvm, now I able to see id nova

as shown below
stack at celestial7:~/devstack$ id nova
uid=123(nova) gid=131(nova) groups=131(nova),129(libvirtd)

also I did su nova and set password for it. 

when tried restarting the nova service I see following error. 
+ cp -p /opt/stack/nova/etc/nova/policy.json /etc/nova
2015-03-09 16:19:21.209 | cp: cannot create regular file '/etc/nova/policy.json': Permission denied

I have done the same on compute node, I am able to see id nova user now. 

also the same error too when try to compile it.  

+ cp -p /opt/stack/nova/etc/nova/policy.json /etc/nova
2015-03-09 16:19:21.209 | cp: cannot create regular file '/etc/nova/policy.json': Permission denied
if any suggestions, will help, I am also trying to debug it. 

thanks for all your support, 

thanks in advance 

regards
Neelu

Use rdo with packstack since it is closer to real life env.

Hello All, 

I have installed openstack using devstack 1 controller and two compute nodes for live migration. 
learnt that need to share ssh keys between compute nodes for nova user. 

When i try to do it, it gives nova user does not exist. 
Allow logins for the nova user 
When I am trying 
usermod -s /bin/bash nova
usermod: user 'nova' does not exist
Please help on this

thanks in advance

This is your error!!!

You need to make sure you have your keys setup correctly.
