The purpose of the code in this directory it to help developers bootstrap a XenServer 5.6 (or greater) + Openstack development environment. This file gives some pointers on how to get started.
Xenserver is a Type 1 hypervisor, so it needs to be installed on bare metal. The Openstack services are configured to run within a "privileged" virtual machine on the Xenserver host (called OS domU). The VM uses the XAPI toolstack to communicate with the host.
Install XenServer 5.6+ on a clean box. You can get XenServer by signing up for an account on citrix.com, and then visiting: https://www.citrix.com/English/ss/downloads/details.asp?downloadId=2311504&productId=683148
For details on installation, see: http://wiki.openstack.org/XenServer/Install
Here are some sample Xenserver network settings for when you are just getting started (Settings like this have been used with a laptop + cheap wifi router):
On your XenServer host, run the following commands as root:
wget --no-check-certificate https://github.com/openstack-dev/devstack/zipball/master unzip -o master -d ./devstack cd devstack/*/
Devstack uses a localrc for user-specific configuration. Note that the XENAPI_PASSWORD must be your dom0 root password. Of course, use real passwords if this machine is exposed.
cat > ./localrc <<EOF MYSQL_PASSWORD=my_super_secret SERVICE_TOKEN=my_super_secret ADMIN_PASSWORD=my_super_secret SERVICE_PASSWORD=my_super_secret RABBIT_PASSWORD=my_super_secret SWIFT_HASH="66a3d6b56c1f479c8b4e70ab5c2000f5" # This is the password for the OpenStack VM (for both stack and root users) GUEST_PASSWORD=my_super_secret # XenAPI parameters # IMPORTANT: The following must be set to your dom0 root password! XENAPI_PASSWORD=my_xenserver_root_password XENAPI_CONNECTION_URL="http://address_of_your_xenserver" VNCSERVER_PROXYCLIENT_ADDRESS=address_of_your_xenserver # Do not download the usual images yet! IMAGE_URLS="" # Explicitly set virt driver here VIRT_DRIVER=xenserver # Explicitly set multi-host MULTI_HOST=1 # Give extra time for boot ACTIVE_TIMEOUT=45 # Host Interface, i.e. the interface on the nova vm you want to expose the # services on. Usually eth2 (management network) or eth3 (public network) and # not eth0 (private network with XenServer host) or eth1 (VM traffic network) # The default is eth3. # HOST_IP_IFACE=eth3 # Settings for netinstalling Ubuntu # UBUNTU_INST_RELEASE=precise # First time Ubuntu network install params # UBUNTU_INST_IFACE="eth3" # UBUNTU_INST_IP="dhcp" EOF
./install_os_domU.sh from the tools/xen directorycd tools/xen ./install_os_domU.sh
Once this script finishes executing, log into the VM (openstack domU) that it installed and tail the run.sh.log file. You will need to wait until it run.sh has finished executing.
If you want to quicky re-run devstack from a clean state, using the same settings you used in your previous run, you can revert the DomU to the snapshot called before_first_boot
