One last question regarding that.

When ptp4l and phc2sys(auto mode) are used on the host, the UTC-TAI offset used with whatever the default is.

But when inside the KVMs , using phc2sys with ptp_kvm, i have to specify the offset manually. So should the offset there be "0" since the hosts system clock has already account for it or should it be the same value set at host level ?

The logs suggested that the delay path was off by +/- 4ns which was

Richard: Does this sound like a workable solution.. ?
Yes, your use case is the reason why ptp_kvm was created in the first
place.  I haven't used it myself, but it sounds like you are using it
to good effect!

Thanks,
Richard
