Hi Stephan,
thanks for the packages, I'll try in the evening.
Could you please confirm the steps to install it:
1) Start with 32 bit Ubuntu 7.10 with 32 bit hypervisor
Well, the 64bit kernel has 32bit compatibility layer enabled. Speaking for
DomU's, I can confirm it works with 32bit userland. There should be no
difference for dom0, but this is unconfirmed. Remember the xen-utils,
libxen and python-xen packages I made are build for 64bit, so installing
them later can leave an ugly arch-mixture...
If you're not glued to some 32bit-only apps in dom0 I would nonetheless
switch over and start with a 64bit Ubuntu 7.10 installation.
2) remove existing hypervisor and xen packages (or issue make uninstall
There's no need to install the 3.1 packages first, but if you want, the
package dependencies in 3.1 / 3.2 should resolve right.
if you have a self build one from mercurial)
I cannot speak for the case of an existent xensource build as I avoided
this always. But having a look at xen-devel/xen-user people do encounter
issues with this.
3) reboot the system with standard ubuntu kernel, non-xen environment
4) install 64 bit hypervisor
keep this for later, see below at 6)
5) install/extract kernel, initrd and modules to necessary locations
yep, sorry for this, but it's always a pain to make kernel packages "the
right way", so you should extract the archive and move kernel and initrd
to /boot, modules to /lib/modules/.
6) install xen packages, libraries, tools and others
install the deb-packages, begin with python-xen and libxen followed by
xen-hypervisor,xen-utils,xen-hypervisor and optionally xen-ioemu and
xen-docs.
7) edit GRUB menu.lst to point to new hypervisor and kernel
Yes, this is straight forward. As an example:
title Xen 3.2 / Ubuntu 7.10, kernel 2.6.18.8-xen
root (hd0,0)
kernel /xen-3.2.gz swiotlb=128
module /vmlinuz-2.6.18.8-xen
root=UUID=2c9954c1-d8f5-477a-a808-39f768b10ac3 ro console=tty0 swiotlb=128
module /initrd.img-2.6.18.8-xen
quiet
(On machines with much RAM (>=32G) and heavy PCIe traffic I found it necessary
to set the swiotlb)
8) reboot and select the new entry
Now what I wonder is, will the 32 bit userland environment boot just
right on top of an 64 bit kernel, or if this does not work, will I be
able to boot the 32 bit kernel on the 64 bit hypervisor?
As said, I can confirm this for domUs. Besides this i would recommend 64bit, so
my scenario differs:
- install 7.10 64bit
- download and install the python-xen,libxen,xen-hypervisor... packages
- optionally, apt-get install the 2.6.22-14-xen image / modules from upstream
repository, this kernel is build on 3.1.0,
but also working (indeed, I found issues with this kernel but in general it
should work also)
- download and copy over the 2.6.18.8 kernel (don't use the 32bit kernel as
dom0 on the 64bit hypervisor)
- optionally, depmod and mkinitramfs a new initrd image. (Depends on your
hardware, but should not be necessary)
- edit grub entry (in general, update-grub should provide all boot combinations)
- reboot
Much luck!
cheers,
Stephan
Thanks,
Emre

Hi Emre,
You might download the packages from
http://boreas.netz-haut.net/pub/
ftp://boreas.netz-haut.net/pub/
To answer your question, i've only made packages of the hypervisor,
not of the kernel.
Anyway, I packed the 2.6.18.8 <http://2.6.18.8> 64bit and 2.6.18.8
<http://2.6.18.8> 32bit kernel, initrd and modules-dir
each into a tar.gz.
Also available are updated packages of xen-tools and rinse pulled
from cvs (or svn?,
cant remember. Thanks to Steve Kemp for working on this.)
Since these packages might be of interest for others, this also goes
to xen-users.
The hypervisor packages differs from the original 3.2.0 release as
listed below:
- pathes are changed to fit the debian/ubuntu way (as done in the
upstream xen-3.1)
(/lib vs /lib64, /etc/xen/ vs. /etc/xen/scripts)
- default network-setup is "dummy"
- hvm bios: i'm currently trying to enhance/beautify the bios, this
is ongoing work
and not ready by now, however it works as expected.
Feel free to give me a note if something doesn't work.
cheers,
Stephan
