[uml-user] Problems in sharing filesystems between Virtual Machines

[Pranjal K. D. <pra...@gm...>]

Hi,
          I am facing a problem in sharing a single root fileystem between
multiple UML instances through COW (Copy on write). I am following the steps
given in
http://user-mode-linux.sourceforge.net/shared_fs.html  for sharing
fileystems between multiple UML instances.

I am using the root_fs.rh-9-full.pristine.20030724.bz2     root filesystem
from  http://www.stearns.org/uml-root/.

When I start my UML instance with ./vmlinux ubd0=root_fs_cow,
root_fs_sh9_pristine  devfs=nomount rw, it failes to boot up saying that
can't open root_fs_cow err=113 etc. As per the steps given in the link it's
not necessary to have a root_fs_cow and willl create when UML booted up
fisrt time, right?


Thanks,
Pranjal
