<p class="MsoNormal">I'm sure someone could make this better, but this is what I've been using and it works well:<br>
<br>
V/R,<br>
<br>
Allan<br>
<br>
1. Create disk image with QCOW2 format<br>
<br>
qemu-img create -f qcow2 /tmp/centos-6.5-working.qcow2 10G<br>
<br>
2. Install CentOS; Install onto a single ext4 partition mounted to “/” (no /boot, /swap, etc.)<br>
<br>
virt-install --virt-type {kvm or qemu} --name centos-6.5 --ram 1024 \<br>
--cdrom=/tmp/CentOS-6.5-x86_64-minimal.iso \<br>
--disk /tmp/centos-6.5-working.qcow2,format=qcow2 \<br>
--network network=default \<br>
--graphics vnc,listen=0.0.0.0 --noautoconsole \<br>
--os-type=linux --os-variant=rhel6<br>
<br>
3. Eject the disk and reboot the virtual machine<br>
<br>
virsh attach-disk --type cdrom --mode readonly centos-6.5 "" hdc<br>
virsh destroy centos-6.5<br>
virsh start centos-6.5<br>
<br>
4. After reboot, login into your new image and modify '/etc/sysconfig/network-scripts/ifcfg-eth0' to look like this<br>
<br>
DEVICE="eth0"<br>
BOOTPROTO="dhcp"<br>
NM_CONTROLLED="no"<br>
ONBOOT="yes"<br>
TYPE="Ethernet"<br>
<br>
5. Add EPEL repository and update OS<br>
<br>
rpm -ivh <a href="http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm" target="_blank">
http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm</a><br>
rpm -ivh <a href="https://yum.puppetlabs.com/el/6/products/x86_64/puppetlabs-release-6-7.noarch.rpm" target="_blank">
https://yum.puppetlabs.com/el/6/products/x86_64/puppetlabs-release-6-7.noarch.rpm</a><br>
<br>
6. Update yum and install cloud-init<br>
<br>
yum -y update<br>
yum install cloud-utils cloud-init parted git<br>
cd /tmp<br>
git clone <a href="https://github.com/flegmatik/linux-rootfs-resize.git" target="_blank">
https://github.com/flegmatik/linux-rootfs-resize.git</a> (installed in place of cloud-initramfs-tools)<br>
cd linux-rootfs-resize<br>
./install<br>
<br>
Edit /etc/cloud/cloud.cfg<br>
<br>
Add the line:<br>
<br>
user: ec2-user<br>
Under “cloud_init_modules”, add:<br>
- resolv-conf<br>
<br>
7. Install and configure puppet<br>
<br>
yum install puppet<br>
edit /etc/hosts and add entry for foreman<br>
edit /etc/puppet/puppet.conf and add the following lines:<br>
<br>
[main]<br>
pluginsync = true<br>
[agent]<br>
runinterval=1800<br>
server = {server.domain}<br>
chkconfig puppet on<br>
<br>
8. Enable the instance to access the metadata service<br>
<br>
echo "NOZEROCONF=yes" >> /etc/sysconfig/network<br>
<br>
9. Configure /etc/ssh/sshd_config<br>
<br>
Uncomment the following lines:<br>
<br>
PermitRootLogin yes<br>
PasswordAuthentication yes<br>
<br>
10. Power down your virtual Centos machine<br>
<br>
11. Clean up the virtual machine of MAC address, etc.<br>
<br>
virt-sysprep -d centos-6.5<br>
<br>
12. Undefine the libvirt domain<br>
<br>
virsh undefine centos-6.5<br>
<br>
13. Compress QCOW2 image with<br>
<br>
qemu-img convert -c /tmp/centos-6.5-working.qcow2 -O qcow2 /tmp/centos.qcow2<br>
<br>
<br>
Image /tmp/centos-6.5.qcow2 is now ready for upload to Openstack<u></u><u></u></p>

That'd be useful. It'd be even better if you could make a quick RDO wiki page[1] that'll be indexed by the search engines.<br>
