[Xen-users] Xen 4.0.1 on Ubuntu Lucid 10.04 - Desktop / Server - 64 Bits - With OpenGL (Intel GEM) enabled - From Linuxcon Brazil! :-D

[Martinx - ジェームズ <thiagocmartinsc@xxxxxxxxx>]

Guys!

 Tomorrow in my "live" presentation at Linuxcon Xen Directions! I'll show the Xen Live CD to the public!
 To celebrate! I want to share my last procedure to get and run Xen 4.0.1 on Ubuntu 10.04 64 bits, here we go:




      The procedure:


 1- Install all the packages:

 aptitude update
 aptitude install bridge-utils build-essential libncurses5-dev dpkg-dev debhelper fakeroot uuid-dev iasl texinfo git-core

 apt-get build-dep xen-3.3

 2- Download, compile and install Xen and its tools:

 cd /usr/src
 wget http://bits.xensource.com/oss-xen/release/4.0.1/xen-4.0.1.tar.gz
 tar xf xen-4.0.1.tar.gz
 cd xen-4.0.1

 make xen
 make tools
 make stubdom
 make install-xen
# make install-tools
 make install-tools PYTHON_PREFIX_ARG=
 make install-stubdom


 3- Download, compile and install Linux from the Jemery's tree:

 make prep-kernels
 wget http://livexen01.worldweb.com.br/linux-config-2.6.23.18-xen-4.0.1-1-tcmc-10.08-1 -O build-linux-2.6-pvops_x86_64/.config


 cd build-linux-2.6-pvops_x86_64
 make menuconfig # Change whatever you want, if you now what you're doing...
 make
 chmod g-s /usr/src/ -R
 make deb-pkg
 dpkg -i ../linux-image-2.6.32.18-tcmc-10.08-1-xen_2.6.32.18-tcmc-10.08-1-xen-*.deb


 depmod 2.6.32.18-tcmc-10.08-1-xen
 update-initramfs -c -k 2.6.32.18-tcmc-10.08-1-xen

 4- Enable Xen at boot:

 update-rc.d xend defaults 20 21
 update-rc.d xendomains defaults 21 20

 5- Configure the Grub2:


 vim /etc/grub.d/40_custom

---- cut here ----
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change


# the ‘exec tail’ line above.

menuentry 'Xen 4.0.1, Ubuntu 10.4 kernel 2.6.32.18' {
        recordfail
        insmod ext2
        set root='(hd0,4)'
        multiboot (hd0,4)/boot/xen-4.0.1.gz dummy=dummy dom0_mem=832M

        module (hd0,4)/boot/vmlinuz-2.6.32.18-tcmc-10.08-1-xen dummy=dummy root=/dev/sda4 i915.modeset=0 earlyprintk=xen ro
        module (hd0,4)/boot/initrd.img-2.6.32.18-tcmc-10.08-1-xen
}
---- cut here ----

 NOTE.: Pay attention to you root partition and also you'll need to disable the KMS (maybe the nomodeset option works for you) of your videoboard.

 update-grub
 reboot

 Choose the right Grub2 menu entry...

 Done!

Cheers!
Thiago
