The key trick is to be able :-

# make world
# make install
# make uninstall
Remove Hypervisor and tools been built with 2.6
# make uninstall

This actions will result Xen packages to be installed in :-
/usr/local/lib/python2.6/dist-packages/xen# ls -l

total 36

-rw-r--r-- 1 root staff 140 2009-05-20 17:20 __init__.pyc

Yes , it's a hack rather then a legal way manage.
Due to real Xen 3.4 build is supposed to be done on Ubuntu 8.10 Server (64-bit) with python2.5 .

The default path for 2.6 is /usr/local/lib/python2.6/dist-packages
The default path for 2.5 is /usr/lib/python2.5/site-packages.

Regular Xen build puts on top of /usr/bin/pygrub:-
  #!/usr/bin/python
i failed to switch this link to 2.5 and had to simulate Xen support
for /usr/bin/pygrub with python 2.6  via fake install.

Attempt to build Xen 3.4 with 2.6 seems to complete fine.
Xen Host looks nice , and "xm info" in particular.
However,  hotplug scripts refuse to work at least through my experience.
What means no DomUs can be created and loaded.

Boris.
BTW
On F11(preview) with python 2.6 everything worked straight away.
I don't remember details now, will check in a week :)

Hi Boris,


thanks for the HowTo for Jaunty, but for some reasons I am not able to run through.

The make install-xen routine ran fine, but

> # make install-tools

came up with an error.
Here is what I got as an output:
/bin/sh: git: not found
make[1]: ***[ioemu-dir-find] Error 127
make[1]: Leaving Directory 'usr/src/xen-3.4-testing.hg/tools
make: *** [tools/ioemu-dir] Error 2

Have you got an idea of what went wrong? Or maybe even a solution?

Thanks for your help!

Greets
Niels
