Re: [Xen-users] Booting dom0: Kernel Panic - not syncing: Attempted to kill init!

[Fabian Lueghausen <lueghausen@xxxxxxxxxxxxxxxxxx>]

I tried this, but the result is the same as before.
Uninstalled the old package and installed xen-3.0.4.1-1.i386.rpm... No Chance!

I also made a new initrd:

depmod 2.6.16-xen
mkinitrd /boot/initrd-2.6.16-xen.img 2.6.16-xen

ls -l /boot/

If you can get to the archives, follow the link to xen 3.0.4,
that has prebuilts for RHEL4 and it supports pae.
It doesn't support 32 on 64 though, and the prebuilts are only
for 32-bit.

There are rhel4.5 prebuilt rpms on xen 3.1.0 too for 32 bit but
I have not tried them.

And as far as the initrd.img, make sure it is a reasonable size,
something like 2.5MB, if you do it wrong it will be much smaller
than that.

Hey Steven,

yes, I did a depmod on the kernel tree and created an initrd after compiling the kernel. This initrd image is being loaded when starting the machine.
The latest prebuilt rpm's on www.xen.org are for RHEL*5*, *not* *4*.
I tried to run the rpm for *xen 3.0.2* and *RHEL4.1* (downloaded in the archiv <http://www.xen.org/download/dl_x30rhel4.html>) but this did not work, because PAE is not supported by this package.
Thanks for this hint!

*More ideas? *

Fabian--did you do a depmod on the kernel tree and do a mkinitrd
on your machine after you compiled the kernel?  The error
you are getting to me looks like you do not have the block
devices loaded right in the initrd images you have and thus
it can't find the root directory to continue
the linux boot, maybe it is not even loading the vmlinuz-2.6.18xen
correctly.

Or did you try to use the pre-built rpms or tarballs for RHEL/SL that
are on the www.xen.org site?  I have not tried the 3.1.0 version
of those on SL4 but there are rpms there for SL4.  I did use the
Xen 3.0.4 precompiled version for SL4 on SL4 and that works fine.

Hello list,

I tried to install Xen 3.1.0 on Scientific Linux (RHEL4), but this mission failed.. Hope you can help me by finding the reason for my problem.
I downloaded the xen sources from http://bits.xensource.com/oss-xen/release/3.1.0/src.tgz/xen-3.1.0-src.tgz and compiled them by running "make" and "./install.sh". This seemed to work.
After setting up grub like this,

I shut down my machine and restarted it. But it won't come up... as you can see right here:

Is there anyone who has an idea what I'm doing wrong?! Tried it by myself for a few hours, but I'm in the dark...

Thanks for every reply to this email!
