Xen users - Apr 2010 - Kernel panic - not syncing: No init found.

Hi,

After shutting down my VM, I can no longer boot. I get the following error:

Kernel panic - not syncing: No init found.

Any ideas on how I might fix this ?


I have tried adding a line
init="/sbin/init"

in the config file, which does not help.

Many thanks Avron

So, it did mount a root filesystem. Usually the "no init found" erros
stem
from a missing root filesystem. Hm, maybe the "root filesystem" was
not
actually "root"? Is your "/" really formatted with ext2, or
could it be
that the "/boot" partition got mounted?

Is it possible that /root got corrupt ?

It''s "/", not "/root" we''re talking about
:-)

Can you mount the rootfs from your dom0 and see if everything is in its 
right place? Can you fsck it?

Um, what exactly do you want to know? Maybe it would help if you post your 
DomU''s config....
