I restart the win10 after I suspend the win10, then follow error message: VM win10_admin2 was started by admin@internal-authz (Host: h4). VM win10_admin2 is down with error. Exit message: Wake up from hibernation failed:(<Element 'disk' at 0x7f8b8c0891d0>, 'source'). Failed to run VM win10_admin2 on Host h4. Why? Please attach any exceptions you see in engine.log and vdsm.log. Best wishes, Greg There has same question when stared Win7_liug Thanks
