Re: [Xen-users] Compile 64 bit hypervisor&kernel on 32bit kernel ?

["Emre Erenoglu" <erenoglu@xxxxxxxxx>]

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
2) remove existing hypervisor and xen packages (or issue make uninstall if you have a self build one from mercurial)
3) reboot the system with standard ubuntu kernel, non-xen environment
4) install 64 bit hypervisor
5) install/extract kernel, initrd and modules to necessary locations
6) install xen packages, libraries, tools and others
7) edit GRUB menu.lst to point to new hypervisor and kernel
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?

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 64bit and 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
