Can you run nova-manage service list ?

Hello again Razique, I was trying to migrate through the terminal and I'm getting this line from my controller node:

nova live-migration f18b6d2b-f685-4476-a7c0-e735db5113cf 192.168.3.3
ERROR: Compute service of 192.168.3.3 is unavailable at this time. (HTTP 400) (Request-ID: req-454960fb-6652-46ed-9080-6d23b384cbb3)

Haven't found anything yet. Any ideas?

Regards.

Guilherme.

I'm migrating it through the dashboard with the admin user. Is it wrong?

Thank you.

Guilherme.

quick question, how do you migrate the instance ? and does it belong to the tenant?

It's still running, no Error messagem from dashboard (it is showing Status: Resize/Migrate - Task: Resizing or Migrating - Power State: Running). The logs are not showing that permission error anymore. Should I wait to see if it will migrate or returns another error status? One thing is true, the machine is really slow now :P

Regards.

Guilherme.

Looks like the file doesn't exist.
Can you spawn a new instance and try to migrate it again?
thanks

For SSH to work the permissions of $HOME/.ssh should look like this:
  drwx------  2 nova nova     76 Ago 15 14:54 .ssh

Use:
  chmod -R go-rwx .ssh
