Re: [Xen-users] Xen-unstable unable to see (any) network card

[Yvette Chanco <yentlsoup@xxxxxxxxx>]

Unfortunately I don't have the immediate answer to your problem, but I
can say that
the age of hardware should not be an issue in and of itself (although
there can always be issues with specific hardware, and I imagine that
somebody else would probably ask you the details of your network
cards, hardware, dmesg, etc., so you might want to post them). We have
Xen (with debian testing/sarge 3.1r0 as a base) running on older
machines (two PIIs, one  350 mgz with 192 mb of ram). My primary
"test" machine has 384 mb of ram and a 900 mhz processor.

Have you tried the Xen demo live cd on the box in question? I haven't
tested 2.0.6 fully, but the 2.0.5 demo was very useful for
troubleshooting, since it supports a lot more hardware than the plain
vanilla installs (and will work on a machine with 256 mb of ram in
text-only mode).

I've also tried most of the installs that you have (except the Debian
unstable version, isn't that Xen 1.2?) with success after some
tweaking - I could give details, but this post is already rather long,
since I'm not actually solving your problem, just commenting on it.
