While playing around in my lab, I wanted to enable VMware Fault Tolerance (FT) for a VM. In the absence of physical HW I use a nested enviroment, which is running on a HP ProLiant DL160 G6 (2x Intel Xeon E5520, 32G RAM, a RAID 0 with 4 SATA drives). FT isn’t available in nested enviroments, because HW virtualization features are required. This screenshot was taken from the web client.
But “isn’t available” doesn’t mean that you can’t enable it. ;) As always this isn’t supported by VMware. It’s for lab enviroments, trainings etc., but not for production. You have to set three configuration parameters for the VM that you want to use with FT. If you use the web client, you can set the configuration parameters as follows:
Edit Settings… > VM Options > Advanced > Edit Configuration…
For easy copy ‘n paste here the parameters:
1
2
3
replay.supported = "true"
replay.allowFT = "true"
replay.allowBTOnly = "true"
After setting the parameters you can enable FT and start the VM.
