[Libguestfs] Kernel panic with virt-builder etc.



Hi there,

I am trying to write an article on virt-builder and managed to compile
version 1.24.1 of libguestfs on Ubuntu 13.10 (I had mixed success with
the git version and 1.25.x). When I am running virt-builder I am getting
an error message:

virt-builder: error: virt-resize failed

Upon further investigation it turns out that there's a kernel panic when
booting the freshly created image. Running the test-tool gives the
following output:

--------------------------------------------------------------------

It looks like "init" is missing, but I wouldn't know as the image gets
deleted after creation. Is there a way to stop libguestfs tools from
doing that?

BTW: the tools *do* require root access when running on Ubuntu because
it (the distro) has the kernel images readable only for root. I
understand that this is not libguestfs's fault, just sayin'...

Thanks for any help.

Best
Oliver
