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

Hello everyone,

I''m quite a newbie with Xen and I''m currently having an issue.
I run Xen 4 on Debian Squeeze x64 and I''m trying to build an OpenFiler
DomU from the Xen domU filesystem tarbal they provide (See
http://www.openfiler.com/community/download/).

I downloaded the tarball and run ''tar xzpvf
/root/soft/openfiler-2.3-x86_64.tar.gz'' to extract the files to the
lvm.

My config file is:

bootloader = ''/usr/bin/pygrub''
vcpus       = ''1''
memory      = ''512''
root        = ''/dev/xvda1 ro''
disk        = [
                  ''phy:/dev/atlantis/openfiler-disk,xvda1,w'',
                  ''phy:/dev/atlantis/openfiler-swap,xvda2,w'',
                  ''phy:/dev/sdb,xvda3,w''
              ]
name        = ''openfiler''
vif         = [ ''ip=192.168.0.204,mac=00:16:3E:C4:D8:AC'' ]
#vfb        = [ "type=vnc,vncunused=1,keymap=fr" ]
extra       = ''console=hcv0 xencons=tty0''
on_poweroff = ''destroy''
on_reboot   = ''restart''
on_crash    = ''restart''

When I create this domain and attach the console, I get the Grub menu and but
soon after it crashes. Here is the console output:

The /etc/inittab on the domU shows:

Any idea on how I could fix the problem ?

Many thanks in advance.
Jean-François.

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

Hi,

I haven''t used OpenFiler before but I am very familiar with Xen on
Debian Squeeze.

Firstly I think have you misspelt hvc0 in the extra line of your config file.
Secondly you should modify initab so that it spawns the getty on hvc0 not xvc0.

The reason the kernel is panicing is that it is unable to bind to a
console to continue booting.
Changing everything to hvc0 should alleviate this problem.

Joseph.

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

Thanks Joseph,

I could fix the issue. Indeed, there was an error in my config file (hcv0 vs
xvco0), but it was not the root cause for the crash. There was also an error in
the domU fstab. Lesson learned: always checked that file when you import a domU
filesystem !
