Comiple xen 3.3 on CenOS 5
Ref: http://www.nikhef.nl/pub/projects/grid/gridwiki/index.php/Xen_on_CentOS_5_-_Notes
1. download two tar files from xen.org
2. Install mercurial src code version manager

wget http://www.selenic.com/mercurial/release/mercurial-0.9.5.tar.gz
tar xvfz mercurial-0.9.5.tar.gz
cd mercurial*
make install
export PYTHONPATH=/usr/local/lib/python2.4/site-packages:${PYTHONPATH}
(if not export that environment variable, you will get an error as this: ImportError: No module named mercurial).

3. Install prerequested packages:


yum install \
gcc make zlib-devel zlib python-devel curses libncurses-devel ncurses-devel openssl openssl-devel \
`yum search xorg-x11|grep dev|grep x86_64|awk -F . '{print $1}'` \
bridge-utils tetex tetex-latex transfig libtool-ltdl dev86 glibc-devel


( for i386 version, replace x86_64 with i386)

4. tar xzf xen*, cd xen*, make world
5. cd dist, sh ./install.sh
6. disable tls:
Put this in /etc/ld.so.conf.d/xen.conf:

# This directive teaches ldconfig to search in nosegneg subdirectories
# and cache the DSOs there with extra bit 0 set in their hwcap match
# fields. In Xen guest kernels, the vDSO tells the dynamic linker to
# search in nosegneg subdirectories and to match this extra hwcap bit
# in the ld.so.cache file.
hwcap 0 nosegneg

Note that the file name _must_ end ".conf". When you've done that, run
/sbin/ldconfig and reboot. The problem should go away.

7. reboot

shrink vmware disk file by cloning harddisk

Ref:

install grub:
http://ubuntuforums.org/showpost.php?p=117829&postcount=2

In summary:
1. install everything on VM1. Then remove unnecessary files.
2. add a second virtual disk.
3. boot from a liveCD,such as Ubuntu desktop 8.0.4
4. partition the second hard disk and copy files to it. (/mnt is the second hard disk)
fdisk /dev/sda (and type 'p' to print the partition table)
fdisk /dev/sdb (and use the n, t, and w commands to recreate the same table)
mkfs.ext3 /dev/sdb1
mount /dev/sdb1 /mnt
cd / (target)
ls egrep -v 'procsyslost.found' > /files.txt
cp -a `cat /files.txt` /mnt
5. Install grub (mbr) to be bootable:
1) Type "grub" in a console
2) Type "root (hd1,0)", or whatever your harddisk + boot partition numbers are (my /boot is at /dev/sdb1, which translates to hd1,0 for grub).
3) Type "setup (hd1)", or whatever your harddisk No. is.
4) Quit grub by typing "quit".
6. shutdown VM. remove the first hard disk.
7. boot.

HowTo: Create a list of installed packages
I found out how to do this recently and thought it might be helpful to some people. To output this information to a file in your home directory you would use,

dpkg --get-selections > installed-software

And if you wanted to use the list to reinstall this software on a fresh ubuntu setup,

dpkg --set-selections

followed by

dselect
