VMWare ESXi 6.5 U2 Intelk RDRAND/RDSEED instruction behavior

Hi,

I have the following configuration :-

• Dell PowerEdge R630 Server

o Hypervisor: VMware ESXi 6.5 U2

o Guest OS : FreeBSD v8.4

o CPU : Intel Xeon E5-2680 v4 2.4 GHz

I'm using Intel provided RDRAND/RDSEED instructions for getting random numbers..

I wanted to know if the instruction  are used in freebsd , whether hypervisor wil

override those Intel instruction RDRAND/RDSEED with its own information,

or the instruction will be directly processed by Intel CPU and data will be relayed back

to the guest os. (Hypervisor doesn't override).

I have some internet sources which says that  to support lockstep mode, hypervisor may override

Intel RDRAND/RDSEED with its own implementation.

Can some one please clarify the  behavior wrt VMware  ESXi 6.5 U2 ?

Thanks.
