# make tools 

fails on Ubuntu 9.04 Server with
Config.mk suggested above

This one Config.mk (untouched) works fine:-

PYTHON ?=  python
PYTHON_PREFIX_ARG ?= --prefix="$(PREFIX)"
# The above requires that PREFIX contains *no
 spaces*. This variable is here
# to permit the user to set PYTHON_PREFIX_ARG to '''' to
workaround this bug:
#  https://bugs.launchpad.net/ubuntu/+bug/362570

Xen Host boots fine.
Pygrub still fails.

But it''s not a core issue (view attached report)!!

Profile bellow fails as well with 2.6.30-rc3-tip :-

This is the line you changed ?  I''m afraid your message wasn''t
very
clear.

This is the feature I put in to let you override the --prefix
specification from the Xen build system, specifically to try to work
around the Ubuntu python installation bug.  If it doesn''t work then
something is wrong.

I returned to default after changing link under /usr/bin
   python->python 2.5 
That is not Ubuntu 9.04 default.

Regarding error with Config.mk, here it goes :-

It looks like my documentation comment was misleading.  It gives a
syntax valid only in the shell, and not in the Makefile.
Try
   PYTHON_PREFIX_ARGin the Makefile.

Yes, now
# make install-xen
# make install-tools
commit builds

Pygrub doesn''t work ( i believe default path is incorrect ) and hotplug
scripts don''t work as well . The last problem makes Xen Host dead.
I''ve tested Suse''s 2.6.27.5 kernel under Xen 3.4 . 
It shows same behavior as 2.6.30-rc3-tip. Problem seems to be on Xen side.
Otherwise,  backend drivers in both xen-ified and pvops kernel refuse to repond
DomU requests.
Something is wrong with python 2.5 setup  on Ubuntu 9.04 Server.
Actually , it seems to be broken in the same way as python 2.6 installed
by default.

Boris.

But xm create now appears to work ?  It''s possible that the fix
didn''t
take properly for pygrub.  Or perhaps that you are running a version
leftover from a previous attempt ?

What errors are in the hotplug logfile ?

*******************************************************
No "xm create -f DomU.cfg" doesn''t appear to work
( *.cfg profile has kernel,ramdisk,root,extra no pygrub
involvment). It''s not leftover due to :-

# make clean
# make uninstall
# make install-xen
# make install-tools
# reboot

What errors are in the hotplug logfile ?

No hotplug.log at all. 
DomU gets paused. Then it may be unpaused
or no , but some time later console reports
