domU image for x86_64 machines?

Is there any NetBSD domU image for x86_64 machines?

If not, can i386 domU image work on x86_64 system? (Sorry if
this is a 
FAQ.)

I saw an email from July about that it was needed to be
done.

I didn't see it on the NetBSD-daily download site.

I found the answer at
http://mail-index.netbsd.org/port-xen/2007/01/02/0000.
html
(I didn't see that before because I search for wrong
thing.)

I still have this question though:

The search terms you want are  "32-on-64"  - I've
not used it (I don't
have 64-bit hardware at prgmr.com, and it's kinda beta so my
consulting 
clients aren't interested in it.)   From what I understand,
it mostly 
works on xen 3.0.4 and it is broken in -unstable (it may
have been fixed 
since...)

>From what I read, it is 32-bit PAE guest on 64 dom0;  as
NetBSD doesn't 
have PAE DomUs running, I doubt it will work for us.

Of course, this is all what I have casually observed from
watching 
xen-devel.  I haven't tried it myself yet.   It is possible
I will be 
playing with it shortly (I'm toying with the idea of using
some 
SATA/amd64 X2 equipment.  it seems that I can get the same
cpu power w/ 
1/4th the power cost of my current 2.0Ghz xeon/fibre channel
setup.  My 
real concern is how the SATA disks will hold up under the
concurrent 
access... but the hardware is cheap enough for me to
"just try it"  and 
see what happens.)
