[Xen-devel] DomU kernel panic due to run-init: /sbin/init: No such file or directory

Hi All,

I'm using xen 4.0.1, kernel, and pygrub to boot. It seems that everything is ok until the last part that run-init is executing. The log says that run-init: /sbin/init: No such file or directory... and then kernel panic - not syncing: Attempted to kill init! I'm trying to figure out how to solve this problem.
I mounted my image and checked the /sbin directory, init was there, but when I boot up with xm create, /sbin directory shows no init. Weirdly, the directory contains small number of files including modprobe.

Please, give me any comment if you have.

Thank you,


Here is my log.
