Enable VMWARE Fault Tolerance (FT) in a Nested ESXi environment

Assuming here that your ESXi environment is already nested and configured appropriately.

Power Off the guest ooerating system you want to enable FT for

Disconnect the CD / DVD (or select client devic eoption)

GO to options tab and sele the Advanced / General Button

ON right hand side click configuration parameters button

Add 3 ROWs

Name: replay.allowFT Value: true

Name: replay.supported Value: true

Name: replay.allowBTOnly Value: true

 

Other Info:

You ned VT-X as a feature of you rphysical CPU adn this needs to be passed through to your Nested ESXI host.

It matters greatly if you are using ESXi 5.0 or 5.1

 

ESXi 5.1 Home Lab Initial Setup

Hardware

 

I recently purchased the following gear to setup a home lab for ESXi 5 study and to of course get my VCP5.

Its a Shuttle XPC with 32GB of DDR3 Ram, Intel i7 3.5ghz and a 3TB SATA3 HDD

I already had a HP microserver N40L with 8GB ram – but with more than 2-3 VM’s it would struggle and subsequently frustrate me greatly …. to say the least 🙂

Virtualisation

I intended to run ESXi 5.1 virtualised so I could really test out the features and not be limited by hardware (like the shuttle only having 1 physical NIC)

The only things I needed to change on the physical shuttle host was

  • add ‘vhv.allow = “true” > /etc/vmware/config
  • Enable promiscuous mode on physical hosts ESXi vswitch
  • Select Other x64 bit client for the VM Client

Shared Storage

I also wanted a NFS and iSCSI device and after downloading OpenFiler from here  https://www.openfiler.com/community/download

Configure it with as an RHEL x64 – 2GB Ram and 2 IDE Disks and 1vCPU

Then I found the following blogs to setup the OpenFiler shares

NFS: http://jreypo.wordpress.com/2010/11/30/configure-nfs-shares-in-openfiler-for-your-vsphere-homelab/

iSCSI: http://techhead.co/how-to-configure-openfiler-v23-iscsi-storage-for-use-with-vmware-esx/
