Sorry for late reply.  Was on vacation last week.

AFAICT no ioctl() is in the pipeline for the host side, except those belong to
/dev/kvm.  

I am not 100% sure about TDX live migration support (TDX 1.5), though.
Supposedly even there are they should belong to /dev/kvm too.  + Wang, wei to
confirm.
