ntpd on openstack nova compute nodes
Raw
gistfile1.txt
If your nova compute nodes stop working properly, and in the /var/log/nova/nova-api.log you get periodic errors:
NeutronClientException: Authentication required
Aside from a misconfiguration, if it happens a short time after the node starts or periodically, the likely culprit is the time
on the node is off and you need to run/install ntpd.
