Hackery Xen 4.0.1-rc1 source & kernels packaged for Ubuntu Lucid @Virtualusr Site up to 4.0.1-rc3

Following bellow is attempt to debianize Xen 4.0.1-rc3,in other words to build debian packages been installed on recent Ubuntu 10.04 (9.10) servers set corresponding version of Hypervisor up. We follow closely posting [1], attempting to fix errors in patching of current version of /etc/init.d/xend.

wget http://virtualusr.files.wordpress.com/2010/06/mk-xen40x6.doc
catdoc mk-xen40x6.doc > mk-xen40x.sh
sh mk-xen40x.sh

Then
# gunzip xen-4.0_4.0.1rc1-0ubuntu1.diff.gz
Edit xen-4.0_4.0.1rc1-0ubuntu1.diff and replace line 835
+xen-4.0 (4.0.1rc1-0ubuntu1) karmic; urgency=low
by
+xen-4.0 (4.0.1rc3-0ubuntu1) karmic; urgency=low

# cp xen-4.0_4.0.1rc1-0ubuntu1.diff xen-4.0_4.0.1rc3-0ubuntu1.diff
# gzip xen-4.0_4.0.1rc3-0ubuntu1.diff
# ./packageXen40x.sh 4.0.1-rc3

Build succeed:-
root@ServerLDX:/usr/src/build# find . -name “*.deb” -print
./400/xen-docs-4.0_4.0.1rc3-0ubuntu1_all.deb

UPDATE 06/22/2010 Due to new errors followed by update “Xen 4.0.1-rc2 … source & kernels packaged for Ubuntu”

Xen 4.0.1-rc2 … source & kernels packaged for Ubuntu

I’ve uploaded to launchpad.net the most recent xen-4.0_4.0.1rc3-0ubuntu1.diff.gz correct version ( per User Virtual )
** Patch added: “xen-4.0_4.0.1rc3-0ubuntu1.diff.gz” http://launchpadlibrarian.net/50750244/xen-4.0_4.0.1rc3-0ubuntu1.diff.gz Packages may be built via original version packageXen40x.sh :-
# ./packageXen40x.sh 4.0.1-rc3
*******************************************************************************************************************************************
Install debian packages been built and load 2.6.32.15 ( which requires rc2) under Xen 4.0.1-rc3 Hypervisor

Make sure:-

root@ServerLNX:/dev/xen# ls -l
total 0
crw-rw---- 1 root root 10, 60 2010-06-17 16:15 evtchn
crw-rw---- 1 root root 10, 59 2010-06-17 16:15 gntdev

It’s a fair . Udevd created evtchn device required for successful xend start under pvops 2.6.32.15. Edit xend, removing attempt to load xen-evtchn module, which in best case scenario would do nothing in worst
case crash xend.
