Hi,
That’s not good at all. And I think it very much should be within the security
boundary.
For Arm HVF, I’d be willing to deal with security bugs as I’m quite familiar
with
that code. But still within S: Maintained, not supported.

So there’s also target/i386/emulate to take into account. Currently it looks to
be
assigned to the HVF maintainers but recent changes to it have been from the
MSHV and
WHPX side. Currently the backends using it are: x86 hvf, mshv, whpx.
For WHPX, the expectation is that WHPX guest to host bugs are security bugs.
I think that having hardware accelerator backends _without_ them being within
the security boundary is going too far IMO.
