nova fails to start server
Hello, after upgrading OpenStack from Newton to Ocata via openstack-ansible, I cannot start any of existing servers:
openstack server list |grep a6200dff-2010-44a2-92ca-3af303ec3577
| a6200dff-2010-44a2-92ca-3af303ec3577 | Win10VDI-3-ephemeral | SHUTOFF | internal=10.0.0.17|
openstack server start a6200dff-2010-44a2-92ca-3af303ec3577
openstack server list |grep a6200dff-2010-44a2-92ca-3af303ec3577
| a6200dff-2010-44a2-92ca-3af303ec3577 | Win10VDI-3-ephemeral | SHUTOFF | internal=10.0.0.17|
Server is still in SHUTOFF state.
nova.log contains the flowing entries:

What could cause this? Thank you.
I must add, that this happens on all compute nodes, - there are no nova errors. Nova just announces that Instance destroyed successfully. instead of starting it, followed by oslo_messaging.rpc.server errors.
