Xen users - Mar 2006 - Debian DomU no network and modprobe errors on xm create

Hi There, I have my debian sarge dom0 on a IBM xSeries 206 with a SATA
drive (seen as /dev/sda) working just peachy with the xen 3.0.1
packages from http://packages.debianbase.de/. I have followed the
instructions for creating a debian domU from these sources:

http://wiki.xensource.com/xenwiki/DebianDomU
http://www.howtoforge.com/perfect_setup_xen3_debian_p4

This is now my current domU config file:

name="dev-domU"
kernel="/boot/xen-linux-2.6.12.6-xen"
root="/dev/hda1"
memory=512
disk=[ ''phy:/dev/xenvg/domu1,hda1,w'',
       ''phy:/dev/xenvg/domu1-swap,hda2,w'' ]
vif=[ '''' ]
dhcp="off"
ip="192.168.1.100"
netmask="255.255.255.0"
gateway="192.168.1.254"
hostname="dev"
#extra="3"

When i create the domU, there is no network and im having issues as
per below... looking at the boot process, im getting this:

Kernel command line: 
ip=192.168.1.100:1.2.3.4:192.168.1.254:255.255.255.0:dev:eth0:off
root=/dev/hda1

and
modprobe: FATAL: Error inserting rtc
(/lib/modules/2.6.12.6-xen/kernel/drivers/char/rtc.ko): Input/output
error

Here are the full outputs: http://gremin.orcon.net.nz/

If someone could take a look and point me in the correct direction on
this one. We are trying to migrate our current dev platform to
seperate xen domU''s for apache/mysql/ftp etc as the first steps in
consolidating our production platform to xen in the future.

Thanks, Simon

first, check if /lib/modules/2.6.12.6-xen/kernel/drivers/char/rtc.ko exists 
on domU

second

edit /etc/default/rcS and put on the lasted line HWCLOCKACCESS=no

and reboot your domU

Simon,
the "IP" Parameter is no longer allowed outside the "vif"
statement.
Comment  it out and see if networking comes up after stopping / starting 
(not "restart"-ing) your domU

Thanks for the TIP, iv updated the conf file to have:

vif=[''ip=192.168.1.100'']

and removed the old line, but still no go. Will keep playing here.

Yep!: "HWCLOCKACCESS=no" is on the last line in the domU''s
/etc/default/rcS file. Here is the output from the boot:

Setting the System Clock using the Hardware Clock as reference...
rtc: IRQ 8 is not free.
modprobe: FATAL: Error inserting rtc
(/lib/modules/2.6.12.6-xen/kernel/drivers/char/rtc.ko): Input/output
error
rtc: IRQ 8 is not free.
modprobe: FATAL: Error inserting rtc

error
System Clock set. System local time is now Sun Apr  2 20:00:36 UTC 2006.

All the rest of the boot seems fine, except that i have not eth0.

If i add a eth0 line to the domU''s /etc/network/interfaces, so that it
looks like this:

auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp

Networking comes up OK, having been assigned the IP from our network
DHCP server... But this is not the correct way todo this is it? As you
are supposed to have the xen assign the IP?
