Open Stack

Hi,

I have OpenStack Juno with multinode setup.
The instance storage is mounted over NFS and is shared between all the
computes.
I am trying to migrate an instance but while doing so the instance runs
into ERROR state by throwing the below error message:

*Failed to launch instance "test_instance": Please try again later [Error:
Unexpected error while running command. Command: ssh 192.168.151.104 mkdir
-p /var/lib/nova/instances/328dc46e-8a1e-44ae-8450-6619b66203cd Exit code:
255 Stdout: u'' Stderr: u'Host key verification failed.\r\n']. *

When I try to execute this command *(mkdir -p
/var/lib/nova/instances/328dc46e-8a1e-44ae-8450-6619b66203cd) *it gets
executed properly.

Can anyone please help in fixing this?

BR,
Varun
