Xen users - Sep 2009 - Installing two versions of xen on the same machine

Hi,
I wanted to use Xen on my Suse box so i installed it from yast. It''s
3.3. Now i have installed another version of Xen 3.4. I want it to
install it form source. I followed the usual steps. make world.

I did not do make install as it would have overwritten some files of
my previous installation.

I wanted to know if there is a cleaner way to do it. Meaning not
copying everything to /boot but having it on my local directory itself
and somehow in the grub mention the vmlinuz and other files to be
picked up from local directory and not  to be picked up from /boot.

Is this allowed or i can only have one version of xen running on my system.

After copying everything correctly i ran into a problem.



1)When i try to build a initrd image using mkinitrd
it says it is not able to find the map file.
I use the following command
mkinitrd  -M map system.map-2.6.18-8-xen -v -f initrd-2.6.18.8-xen 2.6.18.8-xen

Kernel image :    /boot/vmlinuz-2.6.18-8-xen
Initrd image:      /boot/nitrd-2.6.18.8-xen
Kernel Modules:  <not avaliable>
Could not find map System.map-2.6.18.8-xen/boot/System.map. Please
specify a correct file with -M.

I created the file under the above mentioned path and renamed my
system file to System.map as asked. It still throws up the same error.
Could you let me know what could be the issue ?

Have i not correctly copied kernel modules. I have copied the
lib/modules/kernel-version from my local installation to /lib/modules.

thanks
shankha

Pretty much the later. AFAIK Debian has some wrapper scripts for Xen
userland tools to allow multiple versions of Xen coexist, but it''s not
an easy thing to do when you install from source.

Hi,
Thanks for your reply. Could you please let me know what is the
problem with my mkinitrd command. Is it because i may have forgot to
copy some part of the installation. IF yes can we make a wild guess.
Also what are the correct options that should be used while creating
the image.

thanks
shankha

In that case you don''t need to install kernel 2.6.18-8 if you
don''t
want to. You can use your existing kernel.
However installing hypervisor and userland tools will overwrite some
files installed by your OS if your OS already has its own Xen version.

Hi Fajar,
Thanks for your continued help. I checked through yast the following
are installed on my system

1. Kernel-Xen
             The linux kernel for xen paravirtualization.
This kernel can be used both as the domain0 ("xen0") and as an
unprivileged ("xenU") kernel.

Version : 2.6.27.7-9.1  (x86_64)

2. kernel-xen-base
The Linux kernel for Xen paravirtualization.
This kernel can be used both as the domain0 ("xen0") and as an
unprivileged ("xenU") kernel.

2.6.27.7-9.1  (x86_64)

3. kernel-xen-extra
The Linux kernel for Xen paravirtualization.
This kernel can be used both as the domain0 ("xen0") and as an
unprivileged ("xenU") kernel.


2.6.27.7-9.1  (x86_64)

4. xen
This is the xen hypervisor

3.3.1_18494_03-1.8  (x86_64)

4. xen-devel
3.3.1_18494_03-1.8  (x86_64)

This package contains libraries and header files.

When i try to to uninstall this package it says it has a dependency on libvrt.

5.xen - libs
xen virtualization libraries

6. xen - tools
Packages for starting stopping packages.


I guess i can let the  first 3 packages as it is. I will
uninstall the xen hypervisor and other packages related to it.

I can then put the the new hypervisor(3.4)  and related libraries
under /boot and boot with the kernel already installed.

Does it look good or have i made mistakes ?

thanks

Hi,
One more query. When i had build the source code of the xen
hypervisor (make world) it had build the linux kernel also(downloaded
the bits using mercurial).

Would it be possible to just build the hypervisor ?

Isn''t the hypervisor and linux kernel linked ? Pardon my ignorance.

Like is the linux kernel  which is used is specially build to work
with the hyper visor or i can i can build any version of the kernel
and it should work with the hypervisor.

thanks

Correct.

Actually only the hypervisor (xen.gz) is in /boot. The userland part
(tools and libraries) are mostly in /usr.

Good luck.

If you''re using the old kernel you can continue to use the old initrd.
There''s one possible change though: You might need to add
"pci=nomsi"
to kernel parameter.

Should be. I forgot what the command is (is it make tools?) try
looking at README (if available) or makefile.

Anyway, even if it builds and install a new kernel, you can simply
choose not to use the new (2.6.18) kernel and use your old suse kernel
instead.

In general, yes, the hypervisor and kernel is connected. However newer
xen kernel has a compatibility option, by default selected to 3.0.2.
This means that as long as your hypervisor and userland has the same
version, and it''s >= 3.0.2, it should work (minus some
version-specific feature)

I''ve been using Redhat''s kernel-xen (built against
Redhat''s Xen
3.1.2+) with Xen 3.3 and 3.4, and it works great.

Hi,
Little bit of success :-)

I uninstalled the old hypervisor.

I was able to install the new xen hypervisor and boot to the new kernel.

after booting when i said

xend start
Traceback (most recent call last):
  File "/usr/sbin/xend", line 36, in <module>
    from xen.xend.server import SrvDaemon
ImportError: No module named xen.xend.server

I got this error message.

I think my python installation got corrupted somehow because
earlier i was able to run it smoothly. Now it is seems to be
misbehaving. Could this be the reason.

thanks
shankha

Looks like you haven''t properly installed Xen userland tools yet.

Hi,
I have build the tools from source and after building the xen
hypervisor i did a make install which according to README is supposed
to copy the specified files to appropriate places.

I think i am making a mistake. Could you please let me know where i
should place the tools directory or just adding it to the PATH would
do the job.

thanks

Here''s what I did :
- install Opensuse 11.1
- download hypervisor and tools source (not the kernel) from
http://www.xen.org/products/xen_source.html
- extract
- zypper install gcc zlib-devel gettext-tools libopenssl-devel
xorg-x11-devel dev86 SDL-devel ncurses-devel python-devel bridge-utils
- make install-xen
- make install-tools

Hi,
Thanks ... the installation was smooth.

Since my installation of various packages got clumsy
i removed the old Suse installation and installed it fresh.

So i do not have the xen linux kernel. Is there a command to install
the xen kernel seperately ?

One more request. Is there a way to uninstall it cleanly.

thanks
shankha

If you want to use Xen''s 2.6.18 kernel, you can do a "make
help" on
the untarred xen source directory. It will show you how to do lots of
things.

Alternatively, go to http://www.xen.org/products/xen_source.html,
download "Linux 2.6.18 with Xen 3.4.x support source tarball", and
configure it like a normal kernel (make menuconfig, make, etc.)

And there''s newer kernels of course. See
http://wiki.xensource.com/xenwiki/XenDom0Kernels

If you just want to use Suse''s kernel-xen, the obvious way would be to
run "zypper install kernel-xen".

I''m not sure. "make uninstall" MIGHT work, but I
haven''t tested it.
There was a warning on this list sometime ago that "make uninstall"
deletes stuff on /boot with "xen" name on it, whether it''s
installed
by the source or not. I don''t know if it''s still the case.

This is one of the reasons why I prefer using RHEL5 + Gitco. I can
simply do a "yum install" and "yum erase" :D

Hi Fajar,
Thanks a lot for all the help. Installation got over smoothly. There
are some booting issues. I think my scripts which specify the various
boot parameters for xen kernel are not correct. I will try and fix
those. Thanks a lot.

thanks
shankha
