Supported hardware platforms:

    * i386
    * x86_64
    * IA64

Support is developing for the platforms:

    * PPC (stalled)

At this stage I'd rather say "unknown", because I really don't know what's happening.

    * ARM (poor)

I'd say "in progress" - it's not available in mainline Xen yet, but companies do seem to have some sort of commitment to making it work.

    * MIPS port mentioned

No idea if this was mentioned seriously, or just tossed about as an idea.

Can I run a 64-bit HVM-domain in a 32-bit host system?



 Dom0  domU
  32    32     Ok
  32    64     ??
  64    32     Ok
  64    64     Ok


As far as I can understand it is possible
but hypervisor (and domain0) should be PAE-enabled.
No, it's not possible - how should that work (and why would you want to
do it)?

If you really need to start 64bit guests on a 32bit host, you may have
some luck with Qemu emulation, though.

You can, in fact, run a 32-bit PAE dom0 and a 64-bit domU, provided Xen itself is 64-bit. This might even perform better than using a 64-bit dom0, due to various differences between x86_64 and x86_32 - it's crazy stuff.

I meant running a 64bit guest running on a 32bit host sitting on a 32bit hardware.
It's not possible, unless emulated.
