Could you please try to do it properly: 1. Put host to maintenance 2. Enable Kdump integration in PM tab 3. Reinstall the host (click Reinstall when you select the host in Hosts tab) Thanks! This procedure seem to work, engine reporting kdump as activated. It was rather unclear to me, since I run hosted engine: After host deploy they are in the default state, no PM configured. Hence, kdump integration is disabled and will never activate since PM has to be configured in the first place to install. Do you think it is a better idea to always activate kdump in the host deploy stage so it can later be activated correctly with PM configured? Well, I've never tested kdump integration with hosted engine, so adding Sandro to the thread. I'm not sure if there's any value of Kdump integration for the hosted engine itself, but if hosted engine behaves according to following rules, you can be sure that your dump is not lost: 1. When VM with hosted engine is migrated from dumping host to the another host, the VM should have the same FQDN. If not, then you will have to change FenceKdumpDestinationAddress parameter accordingly 2. Also when VM with hosted engine is migrated to another host, not only ovirt-engine service has to started on it but also ovirt-fence-kdump-listener service has to be started Martin Perina Thanks a lot Martin Perina Cheers!
