[Xen-devel] Installing Fedora Core 2 inside an unprivileged domain

I am attempting to install Red Hat Fedora Core 2, inside an
unprivileged Xen domain, using the FC2 distribution DVD.

Ian discusses some options for doing this in a message from 2004-11-07
[ http://sourceforge.net/mailarchive/message.php?msg_id=9983779 ].
I''m developing the "alternative approach" he discusses in the
message.
I''ve made some progress:

  1. Create a sparse file (see section 5.2 of Xen user''s manual):

       dd if=/dev/zero of=fc2-install.img bs=1k seek=8388607 count=1

  2. Acquire the DVD ISO image (FC2-i386-DVD.iso, in my case), and
     save it to a file locally.  Mount the image as a loopback device,
     copy the file "initrd.img" from the DVD image, unmount the image:

       mkdir /mnt/loop
       mount -oloop,ro FC2-i386-DVD.iso /mnt/loop
       cp /mnt/loop/isolinux/initrd.img .
       umount /mnt/loop

  3. Create a configuration file; the important fields to modify are
     "ramdisk" (should point to initrd.img from above),
"disk", and
     "root".  Here are the entries I used:

       kernel  = "/boot/vmlinuz-2.6.9-xenU"
       ramdisk = "/fc2-install/initrd.img"
       memory  = 128
       name    = "fc2-install"
       disk    = [ ''file:/fc2-install/fc2-install.img,hda1,w'',
                   ''file:/fc2-install/FC2-i386-DVD.iso,hdb1,r''
]
       root    = "/dev/hdb1 ro ramdisk_size=8192 init=isolinux.bin"

  4. Start the unprivileged domain.

       xend start
       xm create fc2-install.xen -c

The unprivileged domain starts, Linux starts to boot correctly, and a
"Welcome to Fedora Core" message appears.  But, then a prompt asks
"Do
you have a driver disk?".  When I say "no", it asks what type of
media
contains the packages to be installed (Local CDROM, Hard drive, NFS
image, FTP, HTTP), but selecting any of them brings up a "No driver
found" prompt: "Unable to find any devices of the type needed for this
installation type.  Would you like to manually select your driver or
use a driver disk?"

And that''s where I''m currently stuck.  None of the listed
drivers for
either disk-based or network-based installs appear to work.  My theory
is that the initial boot is successful because Xen is loading the
ramdisk, but in the next stage the installer can''t find drivers for
either the VBD or virtual network interface.  (See boot messages
below.)

But this inability to find the drivers seems odd, since I expect the
drivers for both to be compiled into the xenU kernel.  (Could the
installer somehow be switching over to the kernel image on the DVD?)

So, any ideas on what to try to overcome this?  Rebuild the initrd
image?  Create a driver disk?  Something much simpler?

I don''t think the initrd is going to do you much good: any of the
modules it contains are going to be built for the wrong
kernel. The default xenU kernel probably has everything you need
anyway.

As I understand it, anaconda takes the place of /sbin/init in the
initrd. I suspect what''s happening is that loading of the
modules is failing and anaconda isn''t trying to proceed, even
though it probably could.

I''ve never tried it, but I wander if its possible to run anaconda
directly from an installed system? If so, running it under strace
might provide a useful clue as to what''s going on.

I don''t suppose it will help, but it might be worth exporting the
DVD image as hdb rather than hdb1. If it''s looking for an ISO
image it will look for the former.

It''ll be a shame if we have to hack anaconda to make this work,
but armed with the strace it might be clearer how to trick it
into doing the right thing.  In the longer term, the "Stateless
Linux" project should add what we need to Fedora to make installs
easier.

Thanks,
Ian

The drivers work, but anaconda doesn''t detect the partitions.

I gave up installing FC2 and Debian via the normal installers, and went
with debootstrap, but later I came across a option to anaconda to make
it work like the debootstrap. Try the --rootpath /path option.

I didn''t try it for myself. Good luck.

Luciano Rocha

Re: [Xen-devel] Installing Fedora Core 2 inside an unprivileged domain

Well, drat.  Ian''s and Luciano''s comments are correct: on the
FC2 and FC3
ISO images, the anaconda installer appears to require a successful module 
load before proceeding with an installation.  This is true even when 
mountable block device nodes exist on the system.

I''m going to throw in the towel for now, but there are several possible
continuing approaches if anyone in the future wants to give this a shot:

1. Modify anaconda to automatically bypass the module loading.  There are 
several web sites that discuss modifying anaconda (to resolve specific 
boot issues, such as when using new motherboards), but I unfortunately 
found no good central reference on anaconda itself.

2. Load a bootstrap file system (see below), then invoke the installation 
routines that would normally be called by anaconda.  (Note: it is not 
immediately obvious to me that this is possible without rebuilding 
anaconda; there is a single "loader" executable that''s called
by the
installer''s "init" executable, and "loader" appears
to do everything by
itself.)

3. Recompile the xenU kernel to use modules for the disk and network 
interfaces, then modify the installer''s initrd image to recognize and 
include these modules during its initial probe.

4. As per Luciano''s suggestion, [i] install the anaconda RPM and run it
from the xen0 partition with the --rootpath option or [ii] use the 
"debootstrap" utility with the Red Hat images.  This isn''t
quite solving
the problem I set out to solve (installing Red Hat, wholly within xenU 
domains, with no/few modifications), but this will perhaps allow the 
creation of a file system without requiring both a reboot and an actual 
disk partition.

I was able to run strace on the anaconda "loader" executable, by
booting
xenU directly into the "stage2.img" image included with the ISO
images:

A. Mount the DVD image in loopback mode.

B. Mount the file "Fedora/base/stage2.img" (in the DVD image) in
loopback
mode.  (Note, this is a "cramfs" image, which requires kernel
support.)

C. Create a blank 256MB file (or partition), make an ext2 file system on 
it, mount it, copy the contents of "stage2.img" into it.  [I refer to
this
as stage2-ext2.img below.]

D. You''ll need to make some changes to stage2-ext2.img before booting
from
it, depending on what you want to do below.  At a minimum, you can copy 
the "strace" binary into /usr/bin.  To run the anaconda installer,
you''ll
need to make directories for /proc, /sys, /var/run, and perhaps some 
others.  You also may need to copy some files (for example, search for 
"lang-table" and copy that file into /etc); you''ll see error
messages for
each of these when you try to run anaconda.

E. Start an unprivileged domain with options something like this:

  disk    = [ ''file:/flash/fc2-install/stage2-ext2.img,sda1,w''
]
  root    = "/dev/sda1"
  #extra   = "ro init=/usr/lib/anaconda-runtime/loader/init"
  extra   = "ro init=/usr/bin/bash"

Using the first "extra" line will boot into the anaconda installer,
which
will ultimately fail or get into the no-module-found black hole.  Using 
the second "extra" line will get you a helpful bash prompt and a 
reasonably populated /usr/bin directory.  Unfortunately, invoking
"strace"
on the "loader" executable produced a 500KB file.  In lieu of posting
that
here, I will forward the trace directly to Ian.

I plan to talk with the Anaconda people soon, to make the
above a bit friendlier, as well as allow you to install
multiple versions of the OS like that.

I don''t know if this will follow the --rootpath idea or if
things will look different, but we''ll try to work something
out.

Btw, rawhide should now have RPMs with kernel-xen0, kernel-xen0,
xen and python-twisted ;)

Is it possible to make Xen-U kernels fake the loading of modules?  Every
time someone says "insmod foobar", the kernel would say "ok,
foobar is
now on the lsmod list" but then it doesn''t actually run any code
in the
module.

Would this fake-out anaconda sufficiently?  Or does anaconda run
''insmod'' or ''modprobe'' (in which case
replacing those programs with
symlinks to ''/bin/true'' would fix the problem)?

This was my main concern when trying to create a honeypot;
''lsmod'' looks
different when you''re inside one.

Interesting thought.  I just gave this a try, replacing /usr/sbin/insmod 
with a symbolic link to /usr/bin/true, and it didn''t work: after I 
selected a module to load, it came up with the same messagebox titled "No 
driver found": "Unable to find any devices of the type needed for this
installation type.  Would you like to manually select your driver or use a 
driver disk?"  I tried a module in each of Local CDROM, Hard drive, and 
FTP.

So perhaps the key is first convincing anaconda that it should try loading 
a (any) module, then using the /bin/true trick.  Any idea how anaconda 
(and/or other Linux apps) tests for which devices are present?  Looking at 
the relevant strace info (see below), it seems to get a list of PCI and 
USB signatures, so it must match them somehow against a memory location or 
file contents(?).  (It seems like it''d be fairly heavy-weight to extend
Xen to pretend to export a PCI device just to fool anaconda, but maybe we 
could just create a static file /proc/pci/something with the expected 
entry in it.)

There''s nothing that can be done in the kernel to help this.

Good idea - I think it''s well worth giving this a try by hacking
the initrd.

Re: [Xen-devel] Easy Fedora rootfs recipe sought

ugh, any idea ? i tried

 	yum --installroot=/mnt/RHFC3 -y groupinstall Base

now I get this error :

[...]
   Install: zlib.i386 0:1.2.1.2-1
Downloading Packages:
warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 4f2a6fd2

yet checking the keys it *seems* I have all needed keys installed
In particular I assume that "gpg-pubkey-4f2a6fd2-3f9d9d3b" means the
ID
4f2a6fd2 above

[root@mtdew yum.repos.d]#  rpm -qa gpg-pubkey*
