How to setup sudo with active directory accounts in ESX 4.1
Johnny Zhang
Customer using Active directory integration function in 4.1. the user logged in is DOMAIN/user_name, and since the user is not in the sudoer file, they can not view logs

You can add AD groups into sudoer file
for example, you have a domain called "MYDOMAIN" and the group call "ESX Admins" (or MYDOMAIN\ESX Admins)
you add this under group %wheel:
%MYDOMAIN//ESX/ Admins ALL=(ALL) ALL
Note: if it did not prompt for password, you may need to restart the server, and everything will work from here)

Change virtaul hardware version from 7 back to 4
Johnny Zhang
Some times customers may want to change the virtual hardware version back from 7 to 4, there is a way to do this

the first is the VM's vmx file
the part you need to change is:

virtualHW.version = "7" you change this to
virtualHW.version = "4"

No need to change config.version = "8" since ESX 3.x already using this version

Next what you need to change is:
scsi0.virtualDev = "lsisas1068"

this is default for version 7 of the virtual hardware. Version 4 will not understand this virtual controller

You can change to
scsi0.virtualDev = "lsilogic"

The next step is change the .vmdk file of the VM (pointer file)
ddb.virtualHWVersion = "7"

you need to change this to
ddb.virtualHWVersion = "4"

and after that, you should able to power on the VM as hardware version 4

(please note, this is not supported by VMware)
