Using Debian packages

Using Debian packages

[Lars E. D. Jensen]

Hi list

I'm about to install XenLinux on Debian. And I noticed this repository was 
submitted to this list a while ago:

http://people.debian.org/~doogie/xen/

Does the 2.0.5 packages (kernel-patch-xen_2.0.5-1_i386.deb) apply to Debian 
kernels in the Sarge tree which is 2.6.8 at the moment?

If so, is it possible to build a domU kernel using the debian packages too?

Or should I manually compile a domU from the original Xen 2.0.5 source?

Thanks.

Someone more informed on this than me will probably give you an answer. 
 Until you asked, I just assumed that was the case.

You might be interested in the following:

There is now a beta2 version of the Live Xen CD which I understand is an 
Xen-(Debian) Linux based system now hosting several OS's.  Have not 
tried it myself but saw several postings (very positive).  My only hold 
up is the download which I have arranged to have done on my hehalf by 
another party and has not yet been done.  I am looking forward to 
running this Live Xen system CD (also Xenoboot -- after I build my own 
Xen system).  You might benefit by getting and running the CD before you 
actually do what you are planning because there seem to be a lot of 
similarities.  What is nice about this well made CD is that it works 
"out of the box" so one does not have to struggle with compilation 
issues and other things while they learn about Xen. I believe (someone 
correct me if I am mistaken) that the Live CD comes with all the tools 
you need and this would give us all the opportunity to analyze the 
performance and play with the tools -- something I very much need to do 
in order to understand some of the problems and solutions set out on 
this list. Apparently (from the CD) , you can create additional virtual 
systems and even migrate them. I don't know how they actually make this 
happen from a CD but the people involved with it's making and Xen are a 
sharp bunch.

BTW:  The SuSE list is starting to show a lot of interest in Xen and 
leading Linux magazines and news sources are producing articles on Xen.

If you get the CD let the list know if there are any problems.

Thanks -- Ted

If you've got a kernel built with all the drivers as modules, then
there's little point building a separate domU kernel -- just use the
same for privileged and unprivileged domains.

Most likely not. Xen 2.0.5 does not work with 2.6.8, AFAIK.

It is possible. Just use make-kpkg. make-kpkg --arch=xen
--subarch=xenu would be the way. (As opposed to make-kpkg --arch=xen
--subarch=xen0).

You can do that as well - but you will not get the debian patches to
stock kernels that way.

Hmmm... I really have problems using those packages.

Is there someone who is using those packages, if so... how do you use them?

What kernel-source (from where) are you patching?

Maybe a small step-by-step guide would be good.

My problem is that I can't get a kernel compiled "the debian way" ... into a 
debian package.

I'm not sure if I should use vanilla or not, but I've downloaded the vanilla 
2.6.10 which kernel-patch-xen_2.0.5-1_i386.deb is for (I think). I've 
installed kernel-patch-xen_2.0.5-1_i386.deb and then copied my .config into 
source directory and run:
make-kpkg --added-patches=xen --revision=xenserver.0.1 kernel_image

It compiles fine, but is this the right way of doing it if I want a debian 
package?

"make ARCH=xen menuconfig" fails since there is no xen arch in vanilla.

Also I get this when trying to install the 2.0.5 Debian packages:
Python C API version mismatch for module xen.lowlevel.xu: This Python has API 
version 1012, module xen.lowlevel.xu has version 1011.

Thanks.

Close, but not quite.

You can take a vanilla 2.6.10 or the Debian patched 2.6.10. I would
recommend the Debian patched one. You uncompress the kernel-source
somewhere, copy in your .config, that is fine.

The command you wish to run is:

  make-kpkg --added-patches=xen --arch=xen --subarch=xen0 --revision=xenserver.0.1 debian

This patches the kernel and creates the ./debian directory in your
source. After that you can run:

  make ARCH=xen menuconfig

And tune it to your liking. And after that, you compile the kernel:

  make-kpkg --added-patches=xen --arch=xen --subarch=xen0 --revision=xenserver.0.1 kernel-image

And you are done. Not all of the flags need to be present in all
phases, but it doesn't hurt either. Do also note that make-kpkg has
some problems with --initrd combined with --arch=xen, so don't do
that.

Re: Using Debian packages

[michal urbanski]

I gave up on compiling a kernel the debian way... once I applied the
xen patch by running /usr/src/kernel-patches/i386/apply/xen from
/usr/src/linux, I did the whole "make ARCH=xen" and manually copied the
resulting vmlinuz to /boot/vmlinuz-2.6.10-xen0.

Now, has anyone else had problems with these debian packages? I've built
a U kernel with my same config, and am using this as my vm config:

kernel = "/boot/vmlinuz-2.6.10-xenU"
memory = 256 
name = "test"
disk = ['file:/var/lib/xen/diskimages/test_disk,sda1,w']
disk = ['file:/var/lib/xen/diskimages/test_swap_disk,sda2,w']
root = "/dev/sda1 rw"
restart = 'never'

but whenever I try "xm create -f vm_test", all I get is:

Using config file "./vm_test".
Error: Not Found

Any possible explanations? Have I done something braindead in my vm
config?

Please can you see if there's a more helpful error report in

netstat -anp | grep 8000

Plus, you aren't using the debian packages.  There is no such file
/etc/xend-config.sxp.

Sorry... mistyped, it is in fact /etc/xen/xend-config.sxp

"dpkg -l|grep xen":

... and during all this, I solved my problem. Found an old python2.1,
and an old xen 1.2 package (libxc-python) which after removal, caused 
/etc/init.d/xend to start up properly.

Which is somewhat strange, as /usr/bin/python -> python2.3.

Hrm, that's interesting.  Could you try to track this down more?  The reason I
placed these in experimental, is because I haven't tried doing upgrade
testing; this may be a problem that I need to work around/fix.

xen.gz is the hypervisor. xen-linux-2.6.10 is your kernel. They should
*not* be the same size at all:

-rw-r--r--  1 root root  116602 Feb  4 00:40 /boot/xen.gz
-rw-r--r--  1 root root 2210694 Feb  9 01:36 /boot/xen-linux-2.6.10-xen0-shiro-1

Please reinstall the debian package you made with make-kpkg, you've
probably corrupted your kernel binary somehow.

No, it is not included in the packages. However, I think that is a bug
in the packages - xen.gz should be included, otherwise they are
useless.

> Or should the xen.gz be copied from the binary dist allways?

For now, you should copy it.

Add 'noreboot' on the line where you load xen.gz in grub.
