Having trouble with VMware Fault Tolerance
I found a recent VMware KB article about FT and some common reasons that it might fail to start. The article goes on to explain some reasons why FT options might be greyed out, disabled or you cannot turn on Fault Tolerance. It also talks about requirements that must be met to enable FT. See the full article here.
