Thankyou for responding, that must have been it, then. I don't remember
pulling, but I was doing a number of things to try and get it to boot
dom0 and that is certainly possible. Thanks for being explicit.
I have three new problems with these nodes, I don't know if they are
related problems?
1. on boot the console server swims along until this:
[...]

At the moment the "Failed to..." messages start the console server
seriously drags. After it boots I can log in, there are no more "Failed
to.." reported by dmesg, and there is no lag in the ssh session. (lspci
lists no IRQ's for 4). I am sort of new to Linux, but have never heard
of anything like this.. ?
2. I don't know if this is related, but after I'm logged in, then "xend
start" cuts off all network access. I assume this has something to do
with the bridging code, but I can't figure out what. A look at
xen.xend.* didn't help me much. The brctl tools seem to be working
normally. I feel like I'm missing something obvious..
3. This seems related to the first problem, I get this error when trying
to add the tun module:
# modprobe tun
/lib/modules/2.4.27-xen0/kernel/drivers/net/tun.o: init_module: Input/output
error
Hint: insmod errors can be caused by incorrect module parameters, including
invalid IO or IRQ parameters
/lib/modules/2.4.27-xen0/kernel/drivers/net/tun.o: insmod
/lib/modules/2.4.27-xen0/kernel/drivers/net/tun.o failed
/lib/modules/2.4.27-xen0/kernel/drivers/net/tun.o: insmod tun failed
When I first got these errors, I went back and recompiled everything in
one shot (gcc 3.3.3).
Any ideas? Is there a reason the tun module wouldn't be supported?
Thanks for any insights! I hope to be contributing advice to the list
soon and not just questions :)
