How to Configure Hyper-V v3 & Windows Server 2012 "8" 8250 nested inside ESXi 5.0

Here is an update to the previous blog regarding nested VMs inside ESX 5.0, I wanted to give an update on how to install the Beta of Windows Server 2012 “8” 8250 build and more importantly how to enable Hyper-V role inside the nested VM.
For the majority of the installation of this build the steps remain the same as with Windows 2008 R2 but with a couple of additions.
First make sure you are either runnning ESX 5.0 Update 1 or atleast have patch ESXi500-201112001 installed against ESX 5.0
1. You need to enable hardware virtualization by modifying the etc/vmware/config file. Enable SSH via tech support mode and putty to the ESX5i server
2. Once connected with putty  :
# echo ‘vhv.allow = “TRUE” ‘ >> /etc/vmware/config
3. Next create your Virtual Machine hardware, I personally used hardware version 8 to make things easier with configuration.
4. Before you get to booting up the VM and installing Hyper-V you need to add three lines the virtual machines config file .vmx
You can either add these via the vSphere Client in the settings of the virtual machine > Configuration Parameters, or doing it from command-line
To add them using command-line move back in SSH > change into the directory where you Hyper-V VM is installed
For example config file where my VM is located is called Hyper-V.vmx. Type the following commands:
# echo ‘monitor.virtual_exec = “hardware” ‘ >> Hyper-V.vmx
# echo ‘hypervisor.cpuid.v0 = “FALSE” ‘ >> Hyper-V.vmx
# echo ‘mce.enable = “FALSE” ‘ >> Hyper-V.vmx
5. Next there are a couple of changes to be made with the CPU configuration.
in the VM settings > Options > CPU/MMU Virtualization make sure you select the option to pass the Intel EPT feature.

6. Next move to the Options area > CPUID Mask click on Advanced

Add the following CPU mask Level ECX: —- —- —- —- —- —- –H- —-

8. Finally you are now ready to install Beta Windows 2012 “8” and enable the Hyper-V role.
Additional Notes: Watch out for blank screens once VMtools are installed, if this happens then enable 3D support for your Video card in the VM settings  – See VMware KB
Also when configuring your VM use the E1000 network driver type and not the VMXNET3 as this driver does not work.
Once the Windows server is installed, just enable the Hyper-V role and your all set to start exploring the world of Hyper-V v3.

How to enable SSH on ESX 5 via vSphere Client

OK, so this is probably one of the easiest tasks to perform but its strange how many times I get asked how to enable this for remote access. I guess, most things people are really interested in are the new features which each version of ESX brings and may forget about the mundane stuff you may need for day to day admin.

  • First start the vSphere Client
  • Select the ESXi host in the configurations tab
  • Select Security Profile

  • Click on Properties in the upper right corner and you will get the a popup with all the services on this ESXi 5.0 hosts. Select the SSH service and press the Options button.

  • Now you can start the services and set the startup options

  • press okay and you are done..

that was easy wasn’t it

How to create a bootable USB disk for VMware ESX 5.x installation

One question that I get asked alot is how to create a bootable USB disk especially for installation for ESX and Linux distros. There are probably multiple ways to do this but I effectly use a free tool call UNetbootin, this utility has binaries for Windows, Linux and Mac so works great whatever your desktop of choice, now burning CDs becomes a thing of the past.
1. Download UNetbootin and run the software (WindowsMac OS XLinux).
2. Download the VMware vSphere 5 ISO file -> VMware Download Center.
3. Start the UNetbootin application and choose Diskimage (ISO) and browse to the downloaded ISO file.

4. Choose Type: USB Drive and choose the correct USB drive letter that you want the bootable installer to be installed to( make sure your USB drive is formatted as FAT32 and not NTFS)
5. You are now done! Just make sure you select the correct boot sequence in your BIOS so that the USB drive boots first.

How to suppress "The number of vSphere HA heartbeat datastores for this host is 1 which is less than required 2"

Whilst preparing my ApplicationHA lab for the SE interlock and Symantec Vision in the next couple of weeks, I was busily just making sure that no errors or alarms were triggered and everything looked clean, one thing I did notice and has been there from the start of building the lab, was a message “The number of vSphere HA heartbeat datastores for this host is 1 which is less than required 2”.
The heart beating over a datastore is something that was added with vSphere 5.0, the new FDM HA agent utilizes the storage subsystem as an alternate communication path and typically needs 2 paths to communicate, it’s actually similar to Veritas Cluster Server heart beating which uses 2 extra NICs for heart beating as well as using disk type heartbeats via Coordination Point Server (CPS).

Ok so how to remove or suppressing of the alarm.
There are a couple of ways to remove the message from appearing, the recommended way is to add redundancy via adding another shared datastore to the vSphere cluster or alternatively you can use the “das.ignoreInsufficientHbDatastore = true” attribute in the advanced vSphere HA settings.
1. From within the vSphere Client right-click on the cluster and edit settings.
2. Select the vSphere HA feature and click “Advanced Options”
3. In the options column enter the tag “das.ignoreInsufficientHbDatastore”
4. In the value column enter “true” for the value.
5. Click on “OK” and then “OK” again to make the changes in the advanced options
6. right-click on the ESX server which is displaying the warning symbol and select “Reconfigure for vSphere HA”
That’s it, once the reconfigure task completes the warning should disappear and you are left with a warning icon clean ESX server.

How to reset a lost HP ILO100 admin password with IPMItool

Slightly off the virtualization track but it is lab related…
A new addition to the home VMware lab arrived today, another ML110 G6, these systems are great for building a VMware environment and also have the added benefit of an ILO100 remote management board. I picked this one up from ebay for an amazing £120 and with some additional ram and possibly a CPU upgrade this will still be under £300 and for a quad core 16gb lab machine thats a bargain, finally I can build out SRM permanently intead of using my laptop VMs…
Anyway these ILO cards are great for remote management and I can place my servers out the way from the kids and remotely power on or connect via virtual KVM. The main issue I had with this one was that the admin password was unknown but with the use of the Intel tool  IPMItool its fairly straightforward to reset once a bootable USB stick is created.
follow the steps below to gain access back with your ILO

  • Create a DOS bootable disk (floppy or USB key)
  • Download the IPMItool from this link: 
  • Copy the IPMItool.exe to the bootable disk
  • Boot the server using the bootable disk
  • Run “ipmitool.exe 20 18 47 03 02 61 64 6d 69 6e 00 00 00 00 00 00 00 00 00 00 00”
  • Now your password should reset back to “admin”
