[Xen-users] Newbie question: FC5 boot problem with a blue screen
I followed the instructions at
http://fedoraproject.org/wiki/FedoraXenQuickstartFC5 to install XEN.
After installing FC5, I do
# yum install kernel-xen0
Now /boot/grub/grub.conf is modified to have the FC5 XEN kernel boot option:
title Fedora Core (2.6.17-1.2145_FC5xen0)
root (hd0,4)
kernel /xen.gz-2.6.17-1.2145_FC5
module /vmlinuz-2.6.17-1.2145_FC5xen0 ro root=LABEL=/ rhgb quiet
module /initrd-2.6.17-1.2145_FC5xen0.img
I reboot the computer to the FC5 XEN kernel, the computer is hung with a blue
screen. No message appear on the screen.
How do I debug this problem? (e.g. which log file to look at).

Re: [Xen-users] Newbie question: FC5 boot problem with a blue screen
grub.conf is modified as follows:
default=0
#default=5
timeout=5
splashimage=(hd0,4)/grub/splash.xpm.gz
#hiddenmenu
title Fedora Core (2.6.17-1.2145_FC5xen0)
root (hd0,4)
kernel /xen.gz-2.6.17-1.2145_FC5
#module /vmlinuz-2.6.17-1.2145_FC5xen0 ro root=LABEL=/
module /vmlinuz-2.6.17-1.2145_FC5xen0 ro root=/dev/VolGroup00/LogVol00 3
module /initrd-2.6.17-1.2145_FC5xen0.img
title Fedora Core (2.6.15-1.2054_FC5) original
root (hd0,4)
kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.15-1.2054_FC5.img
title Windows XP
rootnoverify (hd0,1)
chainloader +1
During boot, the computer has a kernel panic, so it will reboot again and stuck
in an infinite loop of rebooting.
If the grub.conf has this line:
module /vmlinuz-2.6.17-1.2145_FC5xen0 ro root=LABEL=/
During reboot to the FC5 XEN kernel, the computer is hung with a lot of the
"avc: denied" messages:
...

Try removing "rhgb quiet" first. Also, I think I''ve read
where "LABEL=/"
is iffy - better to replace it with the full
path "/dev/VolGroup00/LogVol00", or whatever yours might be...

Windows XP and the original and updated FC5 run successfully but FC5 with XEN does not boot.

Re: [Xen-users] Newbie question: FC5 boot problem with a blue screen
Tried several combinations of "selinux=0 setenforce=0 acpi=0" in the
grub.conf file for the boot params to the kernel.
However, still has the same boot problem.
One combination of "selinux=0 setenforce=0 acpi=0" in the grub.conf
file is as follows:
default=0
timeout=5
splashimage=(hd0,4)/grub/splash.xpm.gz
#hiddenmenu
title Fedora Core (2.6.17-1.2145_FC5xen0)
root (hd0,4)

module /vmlinuz-2.6.17-1.2145_FC5xen0 ro root=/dev/VolGroup00/LogVol00 3

Might be the hardware. This thread mentions ATA, but seems to not have a
resolution...

Is it fully "yum update" current (not just the kernel!)? I''ve

Re: [Xen-users] Newbie question: FC5 boot problem with a blue screen
I followed your suggestion to make grub.conf file as follows:
default=0
timeout=5
splashimage=(hd0,4)/grub/splash.xpm.gz
#hiddenmenu
title Fedora Core (2.6.17-1.2145_FC5xen0)
root (hd0,4)
kernel /xen.gz-2.6.17-1.2145_FC5
#module /vmlinuz-2.6.17-1.2145_FC5xen0 ro root=LABEL=/
module /vmlinuz-2.6.17-1.2145_FC5xen0 ro root=/dev/VolGroup00/LogVol00 3
selinux=0 setenforce=0 acpi=0
module /initrd-2.6.17-1.2145_FC5xen0.img
but still has the same problem:
...
unmounting old /dev
unmounting old /proc
unmounting old /sys
switchroot: mount failed: No such file or directory
kernel panic - not syncing : attempt to kill init
...

Have you tried putting the boot parameters on this line?
module /vmlinuz-2.6.17-1.2145_FC5xen0 ro root=/dev/VolGroup00/LogVol00 3
I have discovered this is where Xen expects the kernel boot parameters,
although it doesn''t appear to be well documented. Hope this helps.
