Re: [Xen-users] pygrub setup
Have Mercurial and Git installed on your system.
*********************************************************************************************************************
To port Xen 3.3.2rc1-pre to xen disabled CentOS 5.2 instance (64 bit)
install the most recent version of gitco and mercurial (hg).
**********************************************************************************************************************
# cd /usr/src/
# which git
# which hg
# hg clone http://xenbits.xensource.com/xen-3.3-testing.hg
# cd xen-3.3-testing.hg
# make world
# make install
Determine the name of the Xen Linux kernel version that was installed.
# ls /lib/modules
There should be a directory for the Xen Linux kernel (e.g.2.6.18.8-xen)
Generate the module dependency list and map files
# /sbin/depmod 2.6.18.8-xen
Create the Xen initial ramdisk image
# /sbin/mkinitrd /boot/initrd-2.6.18.8-xen.img 2.6.18.8-xen
Disable tls
# mv /lib64/tls /lib64/tls.disabled
Set xend service to start
# /sbin/chkconfig –add xend
# /sbin/chkconfig xend on
Install bridge-utils:-
# yum install bridge-utils
************************************************************************
Edit /boot/grub/grub.conf and copy one of the existing boot entries
to make the required changes for Xen and reboot into new kernel.
*************************************************************************
title Xen-3.3.2-rc1 CentOS 5.2 x86_64 (2.6.18.8-xen) (/dev/sdb12)
root (hd1,11)
kernel /xen-3.3.2.gz
module /vmlinuz-2.6.18.8-xen ro root=/dev/VolGroup01/LogVol00 rhgb quiet
module /initrd-2.6.18.8-xen.img
Reboot
If you would like to understand how pygrub works try to reproduce:-
http://lxer.com/module/newswire/view/110642/index.html
at your Xen Dom0 ( Linux itself really doesn't matter)
Maybe this one:-
http://lxer.com/module/newswire/view/112300/index.html
would show you more

I am trying to get pygrub to work on a pv that I am building. I am looking at
the page:
http://wiki.xensource.com/xenwiki/PyGrub?highlight=%28pygrub%29
And under "How?" for item number two it
says:
"2.Install a linux-image-xen of your choice."
What exactly are they asking for here? Am I supposed to download xen-3.3.1 and
build it, ala, make xen, make install-xen, make tools, make install-tools,
inside of the vm?
Does it matter what version of xen I am using in dom0?
I will have to build all of this from source because the machine I have to work
on does not have a package management system, like yum, apt or smart.
Any help or extra documentation would be appreciated,
Jon
