[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).

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...

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:
...

audit(1152294237.706:383): avc:  denied  { read write } for pid=2678

I dunno - works for me.
How did you install?
You should have both xen and non-xen grub options for both the current and
previous
kernel releases, plus XP. In other words, five (5) choices. 

Maybe it''s particular to your HW - does the non-xen 2145 kernel work?
(assuming
you have it...)

Re: [Xen-users] Newbie question: FC5 boot problem with a blue screen

Windows XP and the original and updated FC5 run successfully but FC5 with XEN
does not boot.
FC3 does not install because it does not recognize the hard disk (Seagate ATA
ST380110AS).

Might be the hardware. This thread mentions ATA, but seems to not have a 
resolution... 
http://lists.xensource.com/archives/html/xen-users/2005-12/msg00333.html

Is it fully "yum update" current (not just the kernel!)? I''ve
seen a
couple "audit" related threads (mentioned in your orig. post), though 
certainly are fixed now.

selinux=0 setenforce=0 acpi=0 
are some boot params to the kernel you might experiment with...

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)
    kernel /xen.gz-2.6.17-1.2145_FC5 selinux=0 setenforce=0 acpi=0 
    #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

Please don''t top-post. Information up here is not very useful.

Although they are kernel params, I think in the xen context they should
be on the module line, e.g. 
	module /vmlinuz-2.6.17-1.2145_FC5xen0 ro root=/dev/VolGroup00/LogVol00
selinux=0 3
[someone can confirm/deny that, and "someone" else can chime in here 
anytime now... :-)]

And, again, has the machine been updated?

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.
