  Yes, for kernel customization this is the only way I know.

This is some sort of patching latest xen3.4.1 with latest pv os kernel is the only way of getting xen with pv kernels. There are many ways of getting xen in debian.
1- by installing through packages

I do not want to do this because I am interested in benchmarking of different VM's like XEN, KVM etc. So I need specific kernel which is best configured for my hardware. This is why I want to customize linux kernel by myself. By installing through packages, does not allow me to customize the kernel.
 

2- compile and build only xen source if you already have a xenokernel running

Do you know the way of doing that?

3- building xen and xenokernel both from source and patch them 2gether in a grub entry which is menu list in ur case.

By this you mean, I build kernel and xen separately and then by just writing the grub entry, both of them will work together?
 

By the way, is it a srtict requirement to do it in debian and to compile xen from source?
or its just ur choice?

Already clerified.

Thanks a lot for the help.

Thanks for the prompt reply. I am using Debian(Lenny) on amd64. What I want to do is, I want to take fresh vanilla source and build the kernel according to my hardware specifications with XEN Paravirtualized configurations selected. I can do this stuff pretty easily. But I need help in installing XEN hypervisor on it from source.

I do not really understand how you are patching xen installation with kernel installation in the procedure you mentioned below.

Thanks for the explication and help :)

Which platform are you using? Fedora or debian? which version? Below are some basic steps of building it with pv os kernel in a fedora11 platform:-

1. Be certain you have dev tools installed: ‘yum install “Development Tools”‘
2. You’ll also need: ‘yum install mercurial gitk dev86 vnc-server bridge-utils zlib-devel openssl-devel python-devel libX11-devel ncurses-devel’

Build / Install Xen

1. cd /usr/src
2. hg clone http://xenbits.xensource.com/xen-3.4-testing.hg
3. cd xen-3.4-testing.hg
4. make xen
5. make install-xen
6. make tools
7. make install-tools

Build PV Ops Kernel

1. cd /usr/src/kernels
2. git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-xen
3. cd linux-2.6-xen
4. git checkout origin/xen-tip/master -b xen-tip/master
5. make menuconfig (Check the Xen options, I’m too tired to go over them all)
6. make
7. make modules_install install

Create a Grub Entry:

title Xen 3.4 / Fedora kernel 2.6.30-rc6-tip
kernel /boot/xen-3.4.gz
module /boot/vmlinuz-2.6.30-rc6-tip root=/dev/mapper/VolGroup01/vg_fedora11 ro
module /boot/initrd-2.6.30-rc6-tip.img

Add Entry to /etc/fstab

none /proc/xen xenfs defaults 0 0

Reboot and there ya go…

I still need to bring up the python tools like virt-install and virsh, maybe after I get a break.
