x86_64 progress?

x86_64 progress?

[Justin Conover]

1.6 Which architectures does Xen support?

Xen currently runs only on the x86 architecture, requiring a 'P6' or
newer processor (that's any Intel or AMD x86 CPU purchased in the last
five years). Multiprocessor machines are supported, including basic
support for HyperThreading (SMT). A port specifically for x86/64 is in
progress, although Xen already runs on such systems in 32-bit legacy
mode. In addition a port to the IA64 architecture is approaching
completion. We hope to add other architectures such as PPC and ARM in
due course.

Anyone know the progess?  Is there an "unstable/test" i can use?

thx

Anything at all for x86_64 users?

Toa void confusion I should probably have also said "Of course, standard
x86 xen/linux works fine on x86_64 boxen, you just don't get all that 64
bit goodness..."

I think this was discussed already, but I couldn't find the exact
answer - was x86_64 (AMD64, EM64T) port supposed to be able run 32-bit
guests (domain1+) on a 64-bit host (domain0)?

I ask this because I have a very broken driver for an ADSL PCI card
(source driver, not binary, luckily) - it does not like SMP at all,
and I am guessing it does not like 64-bit any more. So unless I come
up with a way to use that card on a 64-bit host, I can't upgrade.
