Checked Builds Of Windows 2008 BSOD STOP: 0x0000008E Error With Vmware

3 April 2010
by Paul McSharry

When creating a Vmware Virtual Machine guest,  running a  Windows Server 2008 checked build from sources such as technet, or MSDN, a blue screen of death may occur ( ie  STOP:0x0000008E).

This is caused by the windows HAL being violated within the Virtual Machine. 

A fix for this issue is to  add the below line to the virtual machine’s configuration (.vmx file).

piix4pm.smooth_acpi_timer = TRUE

by Paul McSharry

In case the server  has no DVD/optial drive or  you have an iso but no DVD-r available.  It is possible to install ESX 4 using a USB flash drive.

1.  Use a bootloader application such as  Unetbootinto create a bootable flash drive using the iso (simply point to the iso file, specify the USB flash drive and click ok) .
2.  Boot the server from the USB flash drive
3.  Click Tab when the ESX install options appear
4.  Add the command askmedia  to the  end of the  syslinux bootloader string  that appears.

The ESX4 installation process will continue as normal, however an additional option of selecting a media path such as USB, FTP and NFS will be available.

The VI Client is excellent, however when you cannot connect to the ESX host,  its time to go to the CLI.
A few useful commands shown below;
Network Card information: ifconfig
Display the network cards availible in ESX: esxcfg-nics -l
Display the network card linked to service console: esxcfg-vswitch -l
Unlink Vmnic from vswitch esxcfg-vswitch -U vmnic0 vSwitch0  
link a vmnic to vSwitch0 esxcfg-vswitch -L vmnic1 vSwitch0
Change the Vlan ID of the console port in ESX: esxcfg-vswitch vSwitch0 -v 15 -p “Service Console” (where 15 is the Vlan ID)
