I can not ping the engine. And no kvm process of engine in any node.

I try to run “hosted-engine --vm-start”, it said:

# hosted-engine --vm-start

Hi,

Can you ping the VM engine? If yes then it's up and running, you may ssh into it and verify the ovirt-engine service if it is running properly.

If the VM engine doesn't ping, search for its kvm process in your hosted nodes (all of them), for example: ps -ef | grep qemu-kvm | grep -i hosted

If the process exists then VM exists but may be it is paused, if it does not, then try to start the VM : hosted-engine --vm-start

When the global maintenance is active if the VM engine is rebooted or shutdown it is not restarted.

Regards.

Hi ovirt list,

I need help.

I ran “dnf update” on my engine and reboot it. Then I lost connection of the engine.

When I access one of my host web management https://ovirthost1:9090, I saw engine status is “Hosted Engine is up!”, but another host of the cluster is in down status.

How can I bring up my engine since it is “UP” now.
