Requirements

• 9GB of RAM ( 1 undercloud, 3 controllers, 1 compute)
  OR
  
• 5GB of RAM ( 1 undercloud, 1 controller, 1 compute)
  

Notes

• Make sure you kill local dnsmasq on the KVM host otherwise you'll have 2 DHCP servers running.
  
• Configure a static IP address on the undercloud VM
  

Deploying the Undercloud/Overcloud on a KVM host

The default setup.cfg configuration permits a full Undercloud/Overcloud deployment on a laptop with 16GB of available RAM. This is against memory recommendations but can work at some extent. 32GB of available RAM is recommended in order to allocate more memory to the controller VMs.

1. git clone https://github.com/david-hill/cloud on the KVM host
2. Generate a root key as root (ssh-keygen -b 2048)
3. Copy the public key on the KVM host in authorized_keys
4. Edit setup.cfg
5. Run create_virsh_vm.sh on the KVM host
6. Run redeploy_undercloud.sh on the KVM undercloud guest
7. In a different window, run "watch.sh" on the KVM undercloud guest

Deploying the Undercloud/Overcloud on Baremetal

1. git clone https://github.com/david-hill/cloud on the undercloud host
2. Edit setup.cfg
3. Run redeploy_undercloud.sh
4. In a different window, run "watch.sh"
