I have juno multinode setup with 1 controller, 2 compute and a network node. While trying to migrate a VM from one compute instance to another the VM instance goes to error state with a SSH error "

{"message": "Unexpected error while running command.                                                   |

I searched for a fix and one of the options was to change nova user shell from /sbin/nologin to /bin/bash.

What do we mean by changing nova user shell and how and where to do it? Also is this a valid option to fix this problem?

Type finger <username> to get the user info. If the shell is /sbin/nologin then user does not have a default shell and he cannot login and execute anything. In order to use SSH command, shell should be configured for the user.

VM migration requires SSH + public key authentication. So that remote commands can be executed without password.
