Oracle VM: Windows Guests Reboot / Fail after An I/O Path Failure (I/O Failover for Windows Guests) (Doc ID 1050916.1)

Last updated on FEBRUARY 03, 2022

Applies to:

Oracle VM - Version 2.1.5 to 2.2 [Release OVM215 to OVM22]
Oracle Cloud Infrastructure - Version N/A and later
Generic Windows


Your Windows 2003 (W2K3) and/or Windows 2008 (W2K8) guests reboot after an I/O path failure on the pool storage. Other guests, for example, Linux, ride out the failure when running on the same Dom0 server.

The Windows Event Viewer only shows this symptom:
Event Type: Error
Event Source: EventLog
Event Category: None
Event ID: 6008
Date: 11/9/2009
Time: 7:40:28 AM
User: N/A
Computer: W2K3_FV
The previous system shutdown at 7:38:09 AM on 11/9/2009 was unexpected.
The problem had been reproduced on the following configuration:
  • OVM 2.2 server (GA) - Boot from SAN (CLARiiON CX4)
  • Windows 2003 R2 VM - Boot from SAN (CLARiiON CX4 & Symmetrix DMX3)
  • Windows 2008 SP1 VM - Boot from SAN (CLARiiON CX4 & Symmetrix DMX3)
  • Virtual Disk - 3 VD attached, all from SAN


Your Storage Area Network (SAN) subsystem experienced a failure, or you are doing destructive testing like pulling cables, powering off switches, etc., in order to test the I/O failover capabilities of your Oracle VM guests.
