Re: [Xen-users] Xen and PPC and ARM

Supported hardware platforms:

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.
