maybe, maybe not. Anyhow you can only practice this with pc bios systems =
and those systems will be gone. And the buggier the emulated bios =
implementations are, the sooner this will happen=E2=80=A6. =20

But, since we now can determine usable disk size from zfs asize, we =
actually can lift the limit, but that limit does not explain errors from =
INT13.=20

So something else is going on there. And since there is no reason to =
build complicated pool layout in virtual machine, I gave my suggestion.
