OLVM: Two KVM Hosts Keep in Non-Responsive in Turn Everytime ovirt-engine Service Restarts (Doc ID 2750847.1)

Last updated on MARCH 10, 2021

Applies to:

Linux OS - Version Oracle Linux 7.8 with Unbreakable Enterprise Kernel [4.14.35] and later
Information in this document applies to any platform.

Symptoms

There are two KVM Hosts in this scenario with SHE engine. The two KVM hosts keep in Non-Responsive in turn everytime ovirt-engine service restarts. That means, there is only one KVM host in 'UP' status.

The debug log error in engine.log is mis-leading, it reports:
