Hello great ML,
Hardly ever would I pose a question when I believe it can be found by
searching the ML archive, this mailing list has been very helpful for me
(thanks!), but now I believe I have encountered odd behavior that needs
to be fixed or discussed. :)
I have two Domain0 Linux 2.6.9 kernel configs, one to run under XEN and
one to run Natively on x86. They have identical building parameters and
boot options (except for including or excluding xen).
Everything works with the native linux kernel, but under xen/xenlinux
network devices are detected but they can't be used.
A side-by-side diff of the kernel output:

The output differences are normal, as far as I can judge with some more
xen hosts. I've noticed that the /etc/interrupt seems to describe
something problematic.
Extracted from the below it seems that eth0 and eth1 do not show up in
/proc/interrupts but do show up in the boot output. I'm able to
configure the interfaces but they never send out a packet, let alone
recieve anything. In the borked an the working system one NIC chipset is
similar. We've never had problems with the NIC's before. XenLinux runs
smooth on other hosts.
Does anyone know where to look for solutions? I've been varying a lot of
options, but this only makes the xen and non-xen bases setup vary more
and less "Cetis Paribus" to be able to do some useful testing. I'd like
to approach the problem in a more rational way. Any pointers?
