[ovirt-users] Create Snapshots on Windows 7 Pro x64 VM's causes Bootload errors

Hello everyone, on Ovirt 4.2.6.4-1.el7, when we try to create a snapshot on Windows 7 Pro x64 (regardless of whether the VM is powered off or not) after several reboots it causes bootload errors (below you'll find a link with screenshoot error). https://ibb.co/tKx6SKw We haven't tried other Windows versions yet, do you have any idea about what the cause might be? Thanks in advance.
