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

[Jean-FranÃois Guyet <jeanfrancois@xxxxxxxxx>]

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 !

Objet: 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.
