I'm trying to record a bit about my research into cloud managment, so I used my old Apple MacPro quad Xeon to give it a try on Centos.
I started out with a Centos 5.4 vanilla install cd (X86_64) and a kickstart file that looked something like this:
install
cdrom
lang en_US.UTF-8
keyboard us
network --device eth0 --bootproto dhcp
## I had multiple network cards... disabled the second one
# network --device eth1 --onboot no --bootproto dhcp
## commenting out the password, set your own
# rootpw --iscrypted 120394871aoeu097123
## for simplicity, disabled firewall and selinux
firewall --disabled
selinux --disabled
authconfig --enableshadow --enablemd5
timezone --utc America/Chicago
## My machine had 4 1Tb drives which I put into a big raid-10
## I clear out all data on all drives, edit to your own liking
#bootloader --location=partition --driveorder=sda,sdb,sdc,sdd
#clearpart --all --initlabel --drives=sda,sdb,sdc,sdd
# part raid.100000 --size=500 --ondisk=sda
# part raid.100001 --size=500 --ondisk=sdb
# part raid.100002 --size=500 --ondisk=sdc
# part raid.100003 --size=500 --ondisk=sdd
# part raid.100007 --size=1 --grow --ondisk=sdd
# part raid.100006 --size=1 --grow --ondisk=sdc
# part raid.100005 --size=1 --grow --ondisk=sdb
# part raid.100004 --size=1 --grow --ondisk=sda
# raid /boot --fstype ext3 --level=RAID1 --device=md0 raid.100000 raid.100001 raid.100002 raid.100003
# raid pv.100008 --fstype "physical volume (LVM)" --level=RAID10 --device=md1 raid.100004 raid.100005 raid.100006 raid.100007
# volgroup vg --pesize=65536 pv.100008
# logvol swap --fstype swap --name=SystemSwap --vgname=vg --size=8000
# logvol / --fstype ext3 --name=SystemRoot --vgname=vg --size=19968

## The post install is where it gets interesting
## Change to virtual termial 3 then download the eucalyptus rpms and install

When the system comes up, run the following to get a simple standalone eucalyptus running.
# make sure these services are started
service eucalyptus-cloud start
service eucalyptus-cc start
service eucalyptus-nc start
# Might want to replace 127.0.0.1 with your external IP
euca_conf --register-walrus 127.0.0.1
euca_conf --register-cluster mycluster 127.0.0.1
euca_conf --register-sc mycluster 127.0.0.1
euca_conf --register-nodes "127.0.0.1"
euca_conf --get-credentials euca-admin-cred.zip
mkdir ~/.euca
unzip euca-admin-cred.zip -d ~/.euca
Download the euca-centos-5.3 image and untar it, the bundle, upload, and register the kernel, ramdisk, and machine images.
# source eucarc
. .euca/eucarc
#kernel
euca-bundle-image --kernel true --image ./euca-centos-5.3-x86_64/xen-kernel/vmlinuz-2.6.27.21-0.1-xen
euca-upload-bundle --bucket centos-kernel-bucket --manifest /tmp/vmlinuz-2.6.27.21-0.1-xen.manifest.xml
euca-register centos-kernel-bucket/vmlinuz-2.6.27.21-0.1-xen.manifest.xml

euca-register centos-root-bucket/centos.5-3.x86-64.img.manifest.xml
Keep trace of the emi, eki, and eri id's that are created and use them to start a new instance of centos:
#ssh keypair creation
euca-add-keypair adminkey > ~/.ssh/id_rsa
euca-describe-keypairs
# KEYPAIR adminkey 95:d5:6a:de:a5:7c:6e:35:ed:61:1b:bf:2c:c9:54:6d:a7:f5:c6:24
euca-run-instances emi-XXXXXXX --kernel eki-XXXXXXX --ramdisk eri-XXXXXX -t c1.medium -k adminkey
Still a work in progress, but feel free to comment.
