yes, that's a known debian deficiancy, it seems that
this is one (the only?) distro where getting apt-rpm
to work is a really tough job ...

if you succeed to get that working, please write a
short howto, guess a lot of folks will appreciate it

vserver  build -m skeleton --context 42  
(see http://linux-vserver.org/alpha+util-vserver for
some examples and most options)

replacing the 'empty' guest dir by your untarred 
mandrake guest should do the trick ...

You wouldn't need to download the (whole bunch of) CDs to get an FC4
guest. Easiest is to use the vserver build command and install the
guest as described in the guide:

Herbert,
A few more solutions...
First three questions:
1) Is one of the FC4 cds bootable?
2) Can you shutdown your target machine?
3) How old is your version of Bash? 

Ans. 3) bash --version
If it is anything older than the 3.0 version that is in 
Debian/Sarge, stop here and upgrade it.

Independent of your answer to #1 and #2 -
use the "vserver  build" command to build
the basic file structure on your system.
I think it has a framework for fc4 

Quick info on the vserver build command enter:
vserver AnyName build --help

A detailed guide to building a generic vserver is at:


There is a minimum chance of trashing your system
with those directions - play with it until you feel ready
to continue.

- - - If you do not want to shut down your machine - - - -

If you are running a linux kernel compatable with
version-2.6.14 plus the vserver-2.0.1 patch on at
least an Intel i686 box...

You can download a compressed version of that
generic vserver from:


Unpack and follow the directions in section 6.7 of
the step by step instructions to wake up the baby.

Bingo - you are now in a virtual server that acts as
if you had booted your machine with the option:
init=/bin/bash

Follow the FC4 installation instructions from the point 
where you are replacing a working system (if those exist)
with a network source of the FC4 stuff.
(I do not expect the current baby01.bin to support
cd/dvd device access.)

- - - - if you can boot from the FC4 install disk - - - -

Well, as Herbert said, find out how to make the
installer do the installation into the directory that
you created with the "vserver  build"
command rather than the entire disk system.

well, as Linux-VServer does not do system emulation
(i.e. you won't get a virtual CD drive and such), just
system (and resource) isolation, you basically have to
solve the problem:
 
"How do I install FC4 from a bunch of CDs into a directory?"

and the solutions could be:

 - use rpm with the --root= option to get the packages
   installed into a dir

 - use UML or QEMU or some full system emulator to
   install the CDs in a virtual machine and copy the
   resulting installing into a directory

 - adjust/adapt (or just trick) the CD installer into
   isntalling FC4 on a separate dir/partition

 - setup a repository (apt-rpm, yum) to install from
   and use the util-vserver tools to install a guest
   from scratch (which is the preferred way)

just to get the idea, what distro/tools where used

if you want the tools to 'create' the IP for
your guest, then you have to tell them on which
interface it shall be done ...

has to be an existing network interface like
eth0 or dummy0 or bond0.10

yes, it is :)

if you leave it out (the dev entry) and add a
'nodev' one instead, then the IP will not be
created, just used ...

[Stephan Mueller]

Hi folks,

I am quite shure this is a stupid question, never the less I would like
to know the answer ;)

What is dev supposed to be set to? The flower page says:

dev: The network device

Hm. Has it to be an existing network interface of the vserver? Or ist it
just a name?

I set it to eth0 and it works but maybe there is more to know about it.

just for the files: I had the same problem today. I was setting up a
staging server for testing the migration of our vservers from the 1.2
branch to to 2.0.1. 

Before I got this error I had several other problems (with incomplete
configs etc.) so I can't tell what to do to reproduce this problem,
sorry.

At least the trick with taring and untaring worked, so I can continue my
tests.

Great idea, thanks trial example, it's easier to understand basic concept and
progress 'step by step' (very educational)

may be use latter with a baby a bit older (I mean when she would learn more
about its environement and could do its first step ;-) )

mmm, wiki seems to be the dreaming tool for that but I don't yet play enough
to advise better how is it easy/difficult to implement (maintenance/update
seem very easy ;-))

Thanks for the share of experience,

hmm, I assume tar looks in /etc/passwd, /etc/group
without that and tries to find an user/group, which
is not there, so it uses -1 (or -2), which looks 
strange to you (2^24-1 = 16777215)

no, in this case I'm tending to believe that the
inode data is wrong/different, but we might have
to look at a 'test' dump to figure that ...

you could mount the partition without tagxid (which 
will give you 'funny' numbers for uid and gid, and
manuall (script) remap them by applying the following
algorithm (please make that on the copy, not the
original)

 uid' = uid & 0xFF
 gid' = gid & 0xFF

as it is *14 not *15, please make sure that the
host where you restore the files has similar entries
in /etc/passwd and /etc/group than the original
(maybe even copy them over for the restore?)

Herbert

Will do.
Thanks for looking at it.

Today's tech-note:

The 'vserver' command is a Bash script that
uses arrays and array functions.

Translation:
Your best bet: Bash-3.1
Probably works: Bash-3.0
A well patched copy of: Bash-2.0b might work, it depends...
If running a Bash version prior to 2.05b - forget it.

Mendel is still very busy, Meaning:
This information may not appear in the
"Advanced Bash Scripting Guide" for awhile.

(So many pots to stir, so few spoons.)

Ok, this is really emberassing to me. I forgot to use --numeric-owner with tar. Though, I don't know 
why (without --numeric-owner) only the GIDs got messed up and not the UIDs (with UGID24)!?


dump/restore still don't work. Might there be a problem because I'm moving the guest systems from 
lvm1 to lvm2?

Hi,

I'm having an issue with some files (group owner) when migrating a
vserver from a 2.4.30-vs1.2.10-vquota (GID24) system, ext3 partitions
mounted with tagctx to the new 2.6.14.3-vs2.0.1 system (GID24,
util-vserver-0.30.209), ext3 partitions mounted with tagxid. The
context id is the same (fixed) on both systems.



you sure that the original partition is mounted with
the proper tagxid (former tagctx) option? i.e. that
the files show sane uid/gid at the 'source'

>

When tarring the files on one vserver and untarring it on the new one,
a few files have different GID's. UID's are correct as far as I can
see.



could you tar a few of those problematic files for
me and upload or attach them to the next mail?


I tarred a few files that have the wrong GID 16777214 find it at:
http://mpex.net/tmp/wrong-xid.tar

mtab entry (on 'source'):
/dev/vg/test /vservers/test ext3 rw,tagctx,usrquota,grpquota 0 0

mtab (on 'destination'):
/dev/vg/test /vservers/test ext3 rw,tagxid 0 0

on the 'source' everything looks fine. uid's/gid's are correct.

here's exactly what I'm doing to transfer the files with dump.
- destination: create lvm2 partition with same size as the old one
- destination: create ext3 fs / mount fs with tagxid option
- source: dump 0zf /tmp/test.dump /vservers/test ; 
- destination: cd /vservers/test ; restore rf /test.dump
- destination: Lots of GIDs are 16777214, UIDs are fine

As we are not really using the tagging on the old and new system for quota (we planned to, but we 
never used it), is there a way to remove it before transfering the guest system via dump, i.e. with 
"chxid -c 0" or something?






Same issue when using dump/restore to transfer the guest system to the
new host. The only difference is, that the GID is 16777214 on those
files.



just to make sure, both systems use UGID24?


yep, triple checked that.





Running chxid with the desired context id from the hostsystem doesn't
change anything.

Any hints? Am I missing anything?



we'll see ...
best,
Herbert

Lars

I have added an abstract, an introduction, and changed the

The morning version of the guide is posted at the same link,
just refresh your copy.
No changes to the baby01.bin file or how to run it.

That file is a Linux/x86 system. It will be awhile before I
can build a hppa-risc version.

That 'vserver' command is a (large) Bash script in front
of the low-level commands. 
That is one of the many things the script does for the
user.

The baby uses the low-level commands for now, just
to expose to the new user what is happening.

Also, she can not be started with "vserver refbox start"
without a bunch of complaints from the vserver script.

I will fix that when I get it figured out.

Today's project is to make a clone of her.

And then try using the file extended attributes and
file access lists.
Maybe I will be able to learn how to protect her from
heavy feet in the host.

I will be updating the step-by-step as I go, also including
anything others mention to me.

Just a comment:
What do you think to put the note in paragraph 5.1:
"Vserver extends the concept of using ..."
better as a general introduction?
(it's the basis but doesn't seems to me enough 'spotlighted')

and a question about the:
mount -o bind /proc /vservers/refbox/proc

why?

In fact, till now, I just used 'vserver DebSid star/stop/enter' and my
DebSid/fstab already contained:
none/proc   procdefaults0 0

Is there a subtle difference, I missed?
