Call for Information! Compiling details on VMware ESX compatibility with HP Proliant ML110 and Ml115′s models.

VMware

Hi all,

I am looking at compiling information on, and presenting via the site, peoples experiences with running VMware ESX (versions 3.0-v3.5, including v3i) on HP Proliant ML110 and Ml115 servers.  I get quite a few queries regarding what is compatible and what isn’t so thought it be a good idea to compile this information, including workarounds, gotchas and hot deals in an easy to follow format.

These are great little, cost effective servers that make an ideal ESX test environment.

HP_ML110_G5

If you can let me know what you have found to work for you, were any tweaks/workarounds required along with any other information you think may be useful to others.

I can confirm that the ML110 onboard storage controller and onboard NIC’s work just fine under v3.5.  See my previous blog article here for more information.

Here’s a rough outline of information to give a basic example.  This will be a work in progress and a fresh blog article created to house this information.

UPDATE: Check out my blog article here on installing VMware ESX 3i 3.5 on an ML110 G5.

Make/Model: Disk Controller: NIC: Work Around?
ML110 G4 SC44Ge NC320i N/A
ML110 G5   NC105i  
ML115   NC320i  
ML115 G5   NC105i

VMWare ESX – Creating a Windows XP VM and getting error: "Setup did not find any hard disk drives installed in your computer."

VMware

Trying to install Windows XP within VMWare ESX and getting the following error message?

"Setup did not find any hard disk drives installed in your computer."

ESX,XP,Drivers

If so not to worry – all that the Windows XP installation process is telling you, as the error message explains, is that it can’t see any available hard disks on which to install XP.

The reason for this is that the necessary hard disk controller drivers have not been installed.

Within ESX there are two types of SCSI controller types available.  These are ‘BusLogic’ or ‘LSI Logic’.

ESX XP Driver

When installing Windows XP the ESX VM will assign the ‘BusLogic’ SCSI controller type as the default.  The Windows XP installation media doesn’t contain the drivers for either of these controllers so unless they are provided via floppy disk at the start of the installation process then XP will not know about any of the disks attached to the controller (which it doesn’t have drivers for).

Using an LSI Logic SCSI controller type has been shown to provide faster performance over that of a BusLogic controller type.

Although only relating to ESX v2.1.1 and Windows Server 2000/2003 this article highlights the performance difference with running a Windows Server OS using a LSI Logic controller under the VM as opposed to BUSLogic.  Ok, I know it doesn’t mention XP but apparently XP also benefits with increased performance (as with W2K3) when using the LSI Logic controller type.

To provide Windows XP with the correct drivers during the installation process following the steps outlined below.

All you have to do to resolve this issue is:

- Download the flp (floppy disk) image for either LSI Logic or BUSLogic from the links below:

*Update Note (March 09): A few people have reported that the newer LSI Logic XP driver doesn’t work.  I would recommend trying the older version first and failing that try the newer version. Thanks to ‘cubeconn’ in pointing out a useful VMware Forum post around this.

LSI Logic XP Driver (Older Version)

LSI Logic XP Driver (Newer Version)

Bus Logic XP Driver

- Upload the flp file(s) to your data/ISO store used by your ESX server.

- From within the XP installations Virtual Machine settings, edit the floppy disk settings and select the flp file containing the SCSI Controller driver you wish to use during the installation process.  Though don’t tick/check the ‘Connect at power on’ box.  Otherwise XP when you go to start the installation will try to boot from the floppy disk and will fail. 
 ESX XP Driver

- Start the installation of the guest OS, in this case Windows XP after creating the VM.

- When prompted to add ‘Additional SCSI Drivers’, press F6 (Function 6 button).

- Connect your floppy disk ISO (flp file) of the SCSI controller driver you wish to use.

- Then press the ‘S’ key to specify an additional device.  The XP installation process should now read this ISO file and will detect the controller drivers.  Press the ‘Enter’ key to continue.

ESX XP Driver

- The XP installation should now detect the disk created for this guess OS and proceed as normal.

- Install VMTools!

Good Luck!

Linksys SLM2008 – A good Gigabit network switch for a VMware ESX test lab.

VMware

Looking for a fully featured but reasonably priced network switch for your ESX test lab?

Check out the Linksys SLM2008.  This 8 port Gigabit ‘Smart’ switch is an ideal candidate for small ESX test labs and contains a number of features found in larger, more expensive switches on the market.

SLM2008 These features include:

- 8 x 1Gb Auto sensing Ports 
-Web management interface.

- Port Based VLAN Tagging.
- Can run off of Power Over   Ethernet (PoE).
- IEEE 802.1Q VLANs
- EEE 802.1X port authentication.
- Support of IGMP Snooping.

The most applicable feature for an ESX test lab is that of using the Port based VLAN functionality to separate the COS, VM OS and VMotion networks.

Below are some screen shots of the main web based management interface and the 2 pages associated with configuring the VLAN tagging.

1. Main Web Based Management Page:

SLM2008_Main

2. VLAN Configuration Page 1:

SLM2008_VLAN1

3. VLAN Configuration  Page 2:

SLM2008_VLAN2

 

Here in the UK the switch retails for approximately £60.  Which when you consider the features and the 8 Gigabit ports this equates to good value for money.

1 x VMware ESX Dual CPU License for 2 x Single CPU Physical Hosts

VMware

This may or may not be common knowledge but you can run two single CPU physical servers on one dual CPU ESX license.

Here’s a link to the VMware site that clarify’s this license usage.

 

Create ISO images for use with VMware ESX OS Guests

Check out the DoISO utility for creating ISO images that you can then use with your VMware ESX OS Guests.

It’s easy to use and best of all.. it’s free!
