8798	Async I/O thread probably stuck in operation	Alex		"One of the VDI files is located at an external iSCSI disk, which
is mounted at the host, because of historical reasons.
At high IO-load at the iSCSI disk an IO_ERR_TIMEOUT event occurs at Win2003r2 Guest and the drive located at that disk will be removed.

The Windows Eventlog is:
""The device, \Device\Ide\IdePort0, did not respond within the timeout period.""
