VMware ESXi 5.x E1000 PSOD Issue

Even though the bug has been fixed I still see it to come up. ESXi 5.x has two issues that might cause the ESXi host to fail with a purple diagnostic screen. Both PSOD look very similiar:


#PF Exception 14 in world wwww:WorldName IP 0xnnnnnnnn addr 0x0
0xnnnnnnnn:[0xnnnnnnnn]E1000PollRxRing@vmkernel#nover+ 0xdb9

Unattended VMware vSphere Client Installation (One-Click Install)

The VMware vSphere Client has an unattended install feature. This feature allows to install the client automatically without interaction. I wrote a little batch file which automatically downloads and installs all versions of the vSphere Client with one click.



Ensure that you run the script as administrator:

@echo off
bitsadmin.exe /transfer "4.1" %tmp%\VMware-viclient-all-4.1.0-1651023.exe
bitsadmin.exe /transfer "5.0" %tmp%\VMware-viclient-all-5.0.0-1917469.exe
bitsadmin.exe /transfer "5.1" %tmp%\VMware-viclient-all-5.1.0-2306356.exe
bitsadmin.exe /transfer "5.5" %tmp%\VMware-viclient-all-5.5.0-1993072.exe

start /wait %tmp%\VMware-viclient-all-4.1.0-1651023.exe /q /s /w /L1033 /v" /qr"
start /wait %tmp%\VMware-viclient-all-5.0.0-1917469.exe /q /s /w /L1033 /v" /qr"
start /wait %tmp%\VMware-viclient-all-5.1.0-2306356.exe /q /s /w /L1033 /v" /qr"
start /wait %tmp%\VMware-viclient-all-5.5.0-1993072.exe /q /s /w /L1033 /v" /qr"

del %tmp%\VMware-viclient-all-5.1.0-2306356.exe
del %tmp%\VMware-viclient-all-5.5.0-1993072.exe

If you need the latest version only:

@echo off
bitsadmin.exe /transfer "5.5" %tmp%\VMware-viclient-all-5.5.0-1993072.exe
start /wait %tmp%\VMware-viclient-all-5.5.0-1993072.exe /q /s /w /L1033 /v" /qr"

vMotion Fails – “The source detected that the destination failed to resume”

Virtual Machine Migration (DRS or user initiated) fails with the following error message:


A genereal system error occurred: The source detected that the destination failed to resume

Error Stack:
The VM failed to resume on the destination during early power on.
Module DiskEarly power on failed.
Cannot open the disk ‘/vmfs/volumes/<…>.vmdk’ or one of the snapshot disks it depends on.
Could not open/create change tracking file

  1. Check that Virtual Disks are not mounted to the backup host (VDP or other products). Sometimes when the backup fails, the virtual disks are not correctly removed from the backup host.
  2. Consolidate Snapshots (Right Click Virtual Machine > Snapshot > Consolidate)
  3. If the problem still persists, create a snapshot and delete it with the “Delete All” option.

How to kill an Unresponsive VM (ESXi 5.x)

When a Virtual Machine crashed it might happen that you cannot power it off with the vSphere Client. In that case, you have to kill the VM through the ESXi command-line.

Connect to the ESXi host with SSH. (If a virtual machine crashed in a cluster and you cannot identify where it is running, you have to identify the ESXi Hosts where the VM is running)

Locate the World ID with esxcli vm process list or vmdumper -l Read more »

Patch ESXi to a Specific Version with the Command-line

This post describes how to patch an ESXi host to a specific version with the command-line. It is highly recommended to use the vSphere Update Manager (VUM) for patch management, but there are some cases where you need an alternative. It’s probably noting you would do in production, but you might need a specific version to reproduce problems or to comply with policies.

In this example, I am going to patch a standalone ESXi 5.5 host with internet access to build number 2068190. The host is currently running ESXi 5.5.0 Build 2302651. (It’s a downgrade)
