Using a 2008 R2 (64bit) guest with 1 vCPU running on all Hosts running Esxi v6 in cluster, I cannot turn on FT for this particular guest. Getting this wonderful message:
" There are fault tolerance compatibility issues, which might prevent you from turning on fault tolerance on the selected virtual machine."
Description : Invalid virtual machine configuration.
I've removed all unsupported hardware, only using LSI SCSI adapter with 2 disks. No CD-ROM, USB, LPT, COMM etc. This guest was a P2V, wondering if that has anything to do with it? I have successfully setup an FT machine that is running 2012 Server OS.
Where can I look to see what is being logged? I scanned the *.log(s) on the Esxi Host it's currently on, nada. Also grepped through the VMWARE-xx.LOG in the datastore, nothing there either?
Any ideas?
Hi The0ray,
I have the same issue.
Have you find a solution ?

In addition to the provided KB article, check if one of the following unsupported features is used by this virtual machine:
vSphere Features Not Supported with Fault Tolerance
Features and Devices Incompatible with Fault Tolerance
Especially snapshots, storage policies and virtual disks with a size of more than 2 TB can be a problem.
Hi,
I already see this KB, and the case was already unchecked ....
I don't undersant .... I have another VM on the same cluster on witch FT is enabled.
I also checked all the check list ...I haven't snapshot on this VM, my VM disk have less than 2TB, I also remove all the virtual devis such cd-rom, floppy.
I also compare with another VM which FT is enabled and i didn't see any difference ...
Number of vCPUs?
Regards
Joerg
Only 2 vCPU and 8 GB Ram
There is also a limit on how many FT VMs and FT vCPUs can run on a host. However, in this case the error message should look different.
But just to be safe: How many FT VMs do you have per hosts and how many vCPUs are covered by FT (Primary & Secondary)?
You can also download the vmx file from a VM that works with FT and from a VM that doesn't and compare these 2 files. Maybe you'll find a difference that explains why it doesn't work with this VM.
Hi,
For the moment, I have only one VM with FT activate.
I will try to compare the VMX.
I will give you some news
