Re: [Xen-users] Kernel panic - not syncing: Attempted to kill init!

["Karsten M. Self" <kself@xxxxxxxxxxxxx>]

Anirban:

The good news:  You're booting your system, it's mounting the root
filesystem, running init, and starting to hit the init.d (sysvinit)
scripts.  Your boot log is telling us this.

The error message:

    Enforcing mode requested but no policy loaded. Halting now.

... looks like it's part of selinux.  I'd make sure that you don't have
any selinux packages installed on your system (a little bird tells me
you're running FC recent).  Confirm with:

    # rpm -qa | grep selinux

...and if you want to delete these (confirm the above output *FIRST*) in
one sweel foop:

    # rpm --remove $( rpm -qa | grep selinux )

... which should work.  No, I haven't tested it.


You'll need to boot your dom0 natively of course to do this, _or_ chroot
into a dom0/domU filesystem image to do the same thing, from another
bootable Linux (native, Xen, Knoppix, etc.).


Cheers.
