Re: [Xen-users] How to boot Ubuntu 9.04(Jaunty) or Debian Lenny (vmlinu
|
Hi Alex!
I'm sure you'll like the new Xen Live CD v2.0.
It is a Debian Lenny dom0 plus 2 read-to-use Ubuntu Server and Ubuntu Desktop on one single CD image!
Take a look at:
It is a great system to learn! ;-)
Cheers! Thiago 2009/6/22 Alexandr R. Ogurtzoff <iscander@xxxxxxxxx>
Hello, I guess it possible distro specific issue but is it resolvable?
I have one node(testing purpose) ganeti 2.0.1 cluster installed over
Debian5 Lenny. Almost everything from distro repositories. Only ganeti
2.0.1 and ganeti-debootstrap are from sources. I have it successful
run with vmlinuz-2.6.26-2-xen-686 and initrd.img-2.6.26-2-xen-686
from repositories. Both Dom0 and DomU are use the same kernel and
initrd. There are symlinks /boot/initrd-2.6-xenU and
/boot/vmlinuz-2.6-xenU pointing to the vmlinuz-2.6.26-2-xen-686 and
initrd.img-2.6.26-2-xen-686. My instance(PVM) run well with following
config generated by ganeti :
node:/boot# cat /etc/xen/app.cluster.xen
# this is autogenerated by Ganeti, please do not edit
#
kernel = '/boot/vmlinuz-2.6-xenU'
ramdisk = '/boot/initrd-2.6-xenU'
memory = 128
vcpus = 1
name = 'app.cluster.xen'
vif = ['mac=aa:00:00:f4:c1:aa, bridge=br0']
disk = ['phy:/var/run/ganeti/instance-disks/app.cluster.xen:0,sda,w']
root = '/dev/sda1'
>

extra = 'clocksource=jiffies'
Then I try to use Ubuntu 9.0.4 (Jaunty) kernel or even Debian's
vmlinuz-2.6.26-2-686-bigmem kernel to boot the instance. I got an
error.
Actually I setup them from repositories and change the symlinks:
node:/boot# ls -l /boot/*xenU
lrwxrwxrwx 1 root root 30 Июн 22 16:25 /boot/initrd-2.6-xenU ->
initrd.img-2.6.26-2-686-bigmem
lrwxrwxrwx 1 root root 27 Июн 22 16:25 /boot/vmlinuz-2.6-xenU ->
vmlinuz-2.6.26-2-686-bigmem
So in this case, my instance bootup stops with following:
node:/boot# gnt-instance startup app (xm create app)
node:/boot# gnt-instance console app (xm console app)

Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/sda1 does not exist. Dropping to a shell!

/bin/sh: can't access tty; job control turned off
(initramfs)
It seems something miss in a initrd. How can I fix it? Should I
rebuild 'default' initrd - which way? Or add something to grub
configuration? Or what do I do wrong? Everything I want for now is to
boot instance with another kernel, and this is not handmade kernel but
kernel from distro repositories what officially noted as suporting
DomU:
http://packages.debian.org/ru/squeeze/linux-image-2.6.26-2-vserver-686-bigmem
it is noted as:
"This kernel also runs on a Xen hypervisor. It supports only
unpriviledged (domU) operation."
Xen is 3.2.1
for Jaunty I tried vmlinuz-2.6.28-11-server
Thank You in advance

Linux is very friendly it is just picky who its friends are
