Hello,
I installed a guest system directly on a LVM volume of my host. I mean this
volume does not
contain a partition table, but directly an ext3 fs.
When I try to use pygrub on it, I receive :
[...]
fs = fstype.open_fs(fn, offset)
File "/usr/lib/python/grub/fsys/ext2/__init__.py", line 35, in
open_fs
return Ext2Fs(fn, offset = offset)
ValueError: unable to open file
Error: Boot loader didn''t return any data!
I checked the values for fn (this is well my LVM volume device driver) and
offset (0 as it must be
if I understand correctly).
The volume can be mounted without problem by the host, and was formatted by the
command "mke2fs -j
/dev/VolGroup/guest_root".
Has someone an idea ?
Thank you

I have reported this about one or two weeks ago to this mailing list and have not yet received a single answer. I don''t have an idea, but I am also interested in a solution. Perhaps it does not work with ext3, only ext2?

(in my working disk image, there is a 100Mb /boot partition). Same problem occurs when I try to use a 96Mb volume directly formatted in ext3 or ext2... ----------------------------------------------------------- Robert Hendrickx.
