Build Xen 3.3.1 src on Ubuntu 8.04

1. Download src from http://www.xen.org/download/
2. Install missing package:
apt-get install libssl-dev mercurial gettext-kde libx11-dev libncurses5-dev patch build-essential texlive-latex-base tetex-bin tetex-extra transfig fig2ps texinfo
3. make a soft link for xgettext:
ln -s /usr/bin/kde-xgettext /usr/bin/xgettext
4. go to xen src directory
make world
5. cd dist
sh ./install.sh
6. depmod 2.6.18.8-xen
update-initramfs -c -k 2.6.18.8-xen
update-grub
7. reboot

Result: can boot into Dom0, but failed to start xend. :(
