--- Comment #16 from igor at hybrid-lab.co.uk ---
(In reply to John Baldwin from comment #15)

The reply from VMWare is in comment #3---their implementation was never broken.
They also asked for specific bug reports to be identified where the buggy
behaviour can be observed; yet, none were provided, and that was back in 2015!

Given that there doesn't seem to be a problem with MSI-X on Linux guests nor
Windows guests, what does the application of Occam's razor yield?.. As for
VMWare, how would anyone even begin to investigate an unexpected behaviour when
that behaviour is only described as "doesn't work in some non-specific
circumstances"?
