good.  esp since I've been doing it for ages ... ;-)

so all that said (thx) ...

why is it, that when I'm trying to "get around" the pci-passthrough
co-assignment requirement -- and both fixes for 34x (as an
unimplemented patch) and 4x (option in config file) are
referenced/available -- AND,i'm (i) on AMD, and (ii) only using
passthrough to PV guests, that I'm being referred to Intel VT-d
documentation for the rationale/explanation that I'm *not* seeing a
bug?

not trying to be difficult here, just seems like the finger's being
pointed at something that's not relevant to my situtation ....


thanks.
