I'll send the patch tonight Razique Mahroua - Nuage & Co razique.mahr...@gmail.com Tel : +33 9 72 37 94 15 <NUAGECO-LOGO-Fblan_petit.jpg> Le 13 févr. 2013 à 20:05, Samuel Winchenbach <swinc...@gmail.com> a écrit : In that documentation it looks like each openstack service gets it own IP (keystone is being assigned 192.168.42.103 and glance is getting 192.168.42.104).    I might be missing something too because in the section titled "Configure the VIP" it create a primitive called "p_api-ip" (or p_ip_api if you read the text above it) and then in "Adding Keystone resource to Pacemaker" it creates a group with "p_ip_keystone"??? Stranger yet, "Configuring OpenStack Services to use High Available Glance API" says:  "For Nova, for example, if your Glance API service IP address is 192.168.42.104 as in the configuration explained here, you would use the following line in your nova.conf file : glance_api_servers = 192.168.42.103"  But, in the step before it set:  "registry_host = 192.168.42.104"? So I am not sure which ip you would connect to here...   Sam On Wed, Feb 13, 2013 at 1:29 PM, JuanFra Rodriguez Cardoso <juanfra.rodriguez.card...@gmail.com> wrote: Hi Samuel: Yes, it's possible with pacemaker. Look at http://docs.openstack.org/trunk/openstack-ha/content/ch-intro.html. Regards, JuanFra 2013/2/13 Samuel Winchenbach <swinc...@gmail.com> Hi All, I currently have a HA OpenStack cluster running where the OpenStack services are kept alive with a combination of haproxy and keepalived. Is it possible to configure pacemaker so that all the OpenStack services  are served by the same IP?  With keepalived I have a virtual ip that can move from server to server and haproxy sends the request to a machine that has a "live" service.   This allows one (public) ip to handle all incoming requests.  I believe it is the combination of VRRP/IPVS that allows this. Is it possible to do something similar with pacemaker?  I really don't want to have an IP for each service, and I don't want to make it a requirement that all OpenStack services must be running on the same server. Thanks... I hope this question is clear, I feel like I sort of butchered the wording a bit.
