[kernel-xen] Converting from bad habits (still)

[Steven Spencer]

List / Joe / All,

I'm trying to take your advice and convert to a flat config file to 
install and run a DomU. I've googled, posted to the list, and made some 
progress, but I'm still not able to even do the install on the guest. 
Again, at this point I'm just trying to get the OS installed and then 
will revert (hopefully) to pygrub for the kernel and ramdisk lines. I'm 
trying to use a kickstart file too, but it isn't even getting that far 
at the moment:

Connfig for install of guest:
-----------------------------
kernel="/boot/vmlinuz-2.6.32-279.14.1.el6.x86_64"
ramdisk="/boot/initramfs-3.6.7-1.el6xen.x86_64.img"
name = "vm_test"
memory = 1024
vcpus = 1
disk = [ 'tap:aio:/virtual/vm_test.img,xvda,w' ]
root = '/dev/xvda ro'
extra="text ks=http://10.10.10.104/sample.ks.cfg"
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'restart'
vif = [ 
"ip=10.10.10.132,mac=00:16:36:35:35:97,bridge=br0,script=vif-bridge" ]
# extra="(hd0)/boot/grub/grub.conf"

I used dd to create a single disk image (vm_test.img above) with the 
idea that the partitioning section of the kickstart file would take care 
of creating the swap for me during build. Here is the kickstart file I'm 
attempting to use too, just in case that is a problem somewhere, though 
I don't see it loading yet in the startup:

install
url --url http://linux.mirrors.es.net/centos/6/os/x86_64/
lang en_US.UTF-8
keyboard us
network --device eth0 --bootproto=static --ip=(removed from email) 
--netmask=255.255.255.0 --gateway=(removed from email) --nameserv
er=(removed from email)
# Bogus password, change to something sensible!
rootpw [password removed from email]
firewall --enabled --service=ssh
authconfig --enableshadow --passalgo=sha512
selinux --disabled
timezone --utc America/North_Dakota/New_Salem
bootloader --location=mbr --driveorder=xvda --append="console=xvc0"

# Partitioning (change sizes and if allowed by installation, ext4 
instead of ext3)
clearpart --all --initlabel --drives=xvda
part / --fstype ext4 --size=20000 --ondisk=xvda
part swap --size=1536 -ondisk=xvda

%packages
@core
@base
@server-platform
@server-policy
pax
oddjob
sgpio
certmonger
pam_krb5
krb5-workstation
perl-DBD-SQLite
%end

What I'm getting when I try to boot, is that xvda apparently is not 
recognised. Do I need to mount the disk image and then fdisk it so that 
it has the xvda device name? When I try to create the guest with the 
config, the process starts and then gets to this point and fails:

XENBUS: Waiting for devices to initialise:

-----------------------

On top of that, I can't seem to get the right combination in the kernel 
= line to add the rdshell for debug.

Any help is appreciated.

Thanks,
