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:
Especially snapshots, storage policies and virtual disks with a size of more than 2 TB can be a problem.
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?
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.
For the moment, I have only one VM with FT activate.
I will try to compare the VMX.
I will give you some news
