You were OK. I misunderstood. Checked and changed VM compatibility mode. It is the same.

Bug – I will continue to troubleshoot. At least to convince myself that this is not caused by hardware used. Then I will file a bug.

Thank you!

I guess I didn't clarify myself.
I asked if you can shutdown the VM and then set only this VM's  'Custom compatibility mode' to 4.2 and power up to test.

Yet, if the cluster was at 4.2 when you imported , then I am afraid that the 'Custom Compatibility mode' won't make a difference.

I'd recommend you to open a bug on bugzilla.redhat.com and share the link with the mailing list. Many of the dev take a look here.

But st Regards,

Yes! It is.

After upgrade 4.2 to 4.3 datacenter and cluster compatibility mode was 4.2 when I discovered the issue. Then I set Cluster mode to 4.3 – no luck. It is not so easy to return it to 4.2.

Thank you!
