Hello, I have an issue with ovirt 4.3 console. The exact issue is, except hosted engine, all other VM's gone to unknown state. I wonder what's the problem is? And how bring back the VM's to normal state. I can see that nothing is enable (for instance, acktivate option, maintaiance option, etc). Can anyone guide me please in this? Thanks in advance! Best Regards, Hariharan
Usually this happens when the engine can no longer reach the host and of course , there is no fencing mechanism to confirm that the node was rebooted. It's interesting that all VMs are in such state ... I would restart the engine itself.

Dear Strahil Nikolov, Thank you for the quick response! Though I restarted teh engine twice from hosted engine but still facing the same problem. I found that ovirt-ha-agent is still in activating state and its not starting yet. Any recomendations please? Best Regards, Hariharan
Have you made any changes recently ? oVirt Engine requires key-based ssh to the Host's root user. If you hardened your hosts recently , modify your /etc/sshd/sshd_config to override that behaviour for the HostedEngine only. Also check the 'supervdsmd.service' & 'vdsmd.service' status - they should be running. The engine's logs might also help.

Dear Strahil Nikolov, Thank you so much for your kind response and immediate help! The issue got resolved and now the hosts got up and running. There was a multiple problems in Hosts and again and again I got same issue. Then finally I rebooted the hosts thrice and also in Ovirt, I confirmed the reboot option. Then it was working fine. Nikolov, I ping you back for last issue regarding gluster storage space issue in Ovirt4.4. cause that issue still not get resolved. Thanks once again! Best Regards, Hariharan

This indicates that perhaps you have not configured power management. You need to have that to avoid these issues.

Dear Alex, Thanks for your kind response! So its mandatory to enable power management? Is that a good way to enable power management in running hosts or already installed hosts in Ovirt? If possible, let me know the benifits of using power management; Thanks in advance! Best Regards, Hariharan

Yes, you need power management and it can be configured at any time. It is needed so as the highly available VMs to be restarted at another host, when one host fails and avoid having zombie VMs in unresponsive state as you faced. Power management is means for the hosts to ensure the state of each other and is a must for high availability.
Thanks in advance!

Dear Strahil Nikolov, Do you have any idea about following error? Couple of weeks back, one VM's OS got corrupted and there's no NIC. Now, I have to re-install the OS in that VM to bring the VM up and running. For doing this, I need to import the ISO domain from gluster storage. While importing the ISO domain, I face the following error; "Error while executing the action: Cannot add memory connection. Memory connection 63566129-bb20-4b11-b5c2-5e943ab94bed already exists" I already searched this "63566129-bb20-4b11-b5c2-5e943ab94bed" image in ovirt server, target server and gluster storage server but I couldn't find it. Could you please help me in resolving this issue? I got stuck badly here. Note: This ISO domain is not present in ovirt engine now; Thanks in advance! Best Regards, Hariharan
Debugging deprecated ISO domain is not easy and actually it will be a waste of time. Is there any reason for not using Data domain for the ISO ? Usually I go to Sotrage -> Disks -> Upload -> Start. In ovirt 4.4 there will be an API for verification of ISOs , but on 4.3 I go in UI after the upload and notice the uuid of the disk (long string) and then you can find it in Gluster and use sha256sum or md5sum to verify the upload. P.S.: about that error, I would look first in the DB.
