Here are RPM repos for Bexar release for OpenStack Nova: http://yum.griddynamics.net

To install Nova on RHEL v.6 you need only two repositories cited on above website and RHEL DVD image connected as repo.

Here are instructions:

Install RHEL 6.0. I usually prefer minimal set of packages.
Connect RHEL 6.0 x86_64 DVD as repository in YUM:

$ sudo mount /dev/cdrom /mnt/cdrom
$ cat /etc/yum.repos.d/rhel.repo 
[rhel]
name=RHEL 6.0
baseurl=file:///mnt/cdrom/Server
enabled=1
gpgcheck=0

1.#3 Download and install repo config and key

$ wget http://yum.griddynamics.net/openstack-repo-2011.1-2.noarch.rpm
$ sudo rpm -i openstack-repo-2011.1-2.noarch.rpm

1.#4 Install manually libvirtd package since we tested our build only on KVM. You could also try Xen without any guarantees :-)

$ sudo yum install libvirt
$ sudo chkconfig libvirtd on
$ sudo service libvirtd start

1.#5 Repeat that setup to all hosts of your cloud

Installation on Cloud Controller node

$ sudo yum install openstack-nova-{api,compute,network,objectstore,scheduler,volume} openstack-nova-cc-config openstack-glance

1.#7 Installation on compute nodes

$ sudo yum install openstack-nova-compute openstack-nova-compute-config

1.#8 Create MySQL db on Cloud Controller node


#!highlight bash
#!/usr/bin/bash

####################################################################
# BIG FAT WARNING:
# ASSUMPTION: a password for root user in MySQL server is `nova' !!!
####################################################################

DB_NAME=nova
DB_USER=nova
DB_PASS=nova
PWD=nova

CC_HOST="A.B.C.D" # IPv4 address
HOSTS='node1 node2 node3' # compute nodes list

mysqladmin -uroot -p$PWD -f drop nova
mysqladmin -uroot -p$PWD create nova
nova-manage db sync

for h in $HOSTS localhost; do
        echo "GRANT ALL PRIVILEGES ON $DB_NAME.* TO '$DB_USER'@'$h' IDENTIFIED BY '$DB_PASS';" | mysql -uroot -p$DB_PASS mysql
done
echo "GRANT ALL PRIVILEGES ON $DB_NAME.* TO $DB_USER IDENTIFIED BY '$DB_PASS';" | mysql -uroot -p$DB_PASS mysql
echo "GRANT ALL PRIVILEGES ON $DB_NAME.* TO root IDENTIFIED BY '$DB_PASS';" | mysql -uroot -p$DB_PASS mysql

1.#9 Fix your configuration in /etc/nova/nova.conf on all nodes based on NovaInstall/MultipleServer

Start your Nova services and enjoy

$ for n in api compute glance network objectstore scheduler volume; do sudo service openstack-nova-$n start; done
$ for n in node1 node2 node3; do ssh $n sudo service openstack-nova-compute start; done

Limitations:

qcow2 images do not supported due lack of NBD support in RHEL
iSCSI LUN do not supported due tgtadm vs ietadm differences

Please route your feedback about that build to abrindeyev@griddynamics.com or to BK_man on IRC.
