[ovirt-users] Windows 2016 guest auto shutdown

I am using ovirt hosted engine 4.2 to manage 5 nodes cluster and Dell Compellent storage domain using ISCSI. The guest is running Windows 2016 OS with ovirt 4.2.4 guest tools installed. The guest presented 1.4 TB thin provision disks and very often, the VM goes offline while doing big file transfer. I didn't find any event errors on OS level. I am wondering if anyone has experienced this issue. Thanks -Aminur
