ESXi will fall back to binary translation if it decides that it cannot
use VMX for some reason. Look at the L2's log file inside ESXi and you
will likely find some errors related to running nested, MSRs KVM does
not emulate properly, or something else that causes ESXi to use binary
translation for its L2.
