Symptoms

Upon creating an OACI VE, it ends up in Failed to delete state.

Starting/stopping a VE results in a failure.

/var/log/pa/vps.log on the OACI IM node contains the messages:

2017-08-18 15:01:12,837 (aps_2d4a4257-f53f-4a16-a6bc-ff209670274a_102) WARN  Heartbeat [Shared executor thread #2 @1 @INTERACTIVE] - invoke stop_ve_cb to route 10.39.54.11 state: OPEN value: -93 ms

Cause

There is a time drift between OACI nodes, which causes negative values in the vm2vf service heartbeat calculation.

Resolution

Configure NTP or any other time synchronization in the OACI environment to make sure there is no big difference in time between the nodes.
