Here are RPM repos for Bexar release and also per-commit trunk builds 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:

1. Install RHEL 6.0. I usually prefer minimal set of packages.
2. Disable SELinux in /etc/sysconfig/selinux. Reboot.
3. 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.#4 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.#5 Install manually libvirt 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.#6 Repeat that setup to all hosts of your cloud

1. Installation on Cloud Controller node

$ sudo yum install euca2ools openstack-nova-{api,compute,network,objectstore,scheduler,volume} openstack-nova-cc-config openstack-glance

1.#8 Installation on compute nodes

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

1.#9 Create MySQL db on Cloud Controller node

$ sudo service mysqld start
$ sudo chkconfig mysqld on
$ sudo service rabbitmq-server start
$ sudo chkconfig rabbitmq-server on
$ mysqladmin -uroot password nova

#!highlight bash
#!/bin/bash

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

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

nova-manage db sync

1.#10 Fix your configuration in /etc/nova/nova.conf on all nodes based on NovaInstall/MultipleServer

1. Start your Nova services and enjoy

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

Limitations:

• iSCSI LUN do not supported due tgtadm vs ietadm differences
• Only KVM hypervisor support tested

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