[Xen-users] CentOS installation procedure

["Joe Noon" <joenoon@xxxxxxxxx>]

I created this procedure several months ago.  The details are slightly
fuzzy, but the reason for several of the steps are due to glibc/xen
issues (which I dont entirely understand.. maybe someone can clear
that up as well?).  If you have setting up a CentOS 4.3 dom0 down to a
science, please comment on anything you do differently, why you would
add a step, remove a step, etc.  It would be nice to have a simple
"this is how its done" howto that is nice and current.

So here are my CentOS 4.3 steps:

yum update
yum install bridge-utils
yum install kernel-headers

download and untar the rhel 4.1 xen rpms, then cd into the directory

tar xvf xen-3.0-x86_32-rhel4.1.bin.tar
cd xen-3.0-x86_32-rhel4.1.bin
mv glibc-2.3.4-2.9xen2.i386.rpm glibc-2.3.4-2.9xen2.i386.rpm.old
mv nptl-devel-2.3.4-2.9xen2.i386.rpm nptl-devel-2.3.4-2.9xen2.i386.rpm.old
nano /etc/yum.conf

exclude packages which we only want to use the xensource rpms for. add
the following line to the [main] section:

exclude=glibc glibc-common glibc-devel glibc-headers glibc-profile
glibc-utils nptl-devel nscd xen xen-devel xen-kernel

install the xensource provided rpms forcibly as they are older than
the versions already installed.

rpm -ivh --force glibc-*.rpm
rpm -ivh --force nptl*.rpm
rpm -ivh --force nscd*.rpm
rpm -ivh --force xen-*.rpm

add a section to /boot/grub/menu.lst:

title Xen (2.6.16-xen3)
       root (hd0,0)
       kernel /xen-3.gz com1=115200,8n1
       module /vmlinuz-2.6-xen root=/dev/VolGroup00/LogVol00 ro
maxcpus=1 console=tty1 console=ttyS0,115200n8
       module /initrd-2.6-xen.img


Thanks,

Joe
