 Yes key is now owned by nova user in default dir /var/lib/nova/.sshThis 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

 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 userWhen I am trying 
usermod -s /bin/bash nova
usermod: user 'nova' does not exist
Please help on this
thanks in advance
