Hi,

I'm sure this must be documented somewhere, but I can't find it.

Is there a document somewhere that shows which permutations of 64/32
bits are known to work or known not to work with XEN 3.0.2 on 64-bit
hardware?

I.e. which of the following eight permutations work:

 - 64-bit dom0 OS with 64 bit HVM domU OS    (?)
 - 64-bit dom0 OS with 32 bit HVM domU OS    (?)
 - 64-bit dom0 OS with 64 bit paravirt domU OS (?)
 - 64-bit dom0 OS with 32 bit paravirt domU OS (?)
 - 32-bit dom0 OS with 64 bit HVM domU OS    (?)
 - 32-bit dom0 OS with 32 bit HVM domU OS    (WORKS)
 - 32-bit dom0 OS with 64 bit paravirt domU OS  (?)
 - 32-bit dom0 OS with 32 bit paravirt domU OS  (WORKS)

If this is not documented somewhere, maybe folks on this list wouldn't
mind replying with any knowledge they may have.  For example, if you
know one works because you've tried it yourself, or you know one
doesn't because it's excluded by some architectural design decision,
or whatever.

Thanks,
Derek.

(I've only used 32bit-dom0 + 32-bit-HVM-dom0 so far, but planning to
upgrade my dom0 to 64-bit Gentoo soon.)
