Hello Alex, great to hear that! Comparing the two approaches will definetely be an interesting thing once we have comparable solutions for both methods available (i.e. glance or keystone integration for ZooKeeper or Nova in- tegration for Pacemaker). The reason I started with Glance and Keystone is the fact that I expect it to be particularly more difficult to catch all odds and ends when it comes to integrating Nova into Pacemaker. For example, verifying that a process called "nova-network" is running isn't difficult, but making sure that on the very same system exactly the network-configuration is in place (iptables-wise etc. pp.) that is necessary to consider nova-network running is a lot harder. I'm completely open if anyone has ideas on how to fiddle with this the best way :) Best regards Martin -- Martin Gerhard Loschwitz Chief Brand Officer, Principal Consultant hastexo Professional Services CONFIDENTIALITY NOTICE: This e-mail and/or the accompanying documents are privileged and confidential under applicable law.
