There isn't an "HA" mode so much as making the components HA. Most of the components are easy to do in that respect - known setups for MySQL, etc. RabbitMQ poses some complications, but there's known recipes for making that failover, and the latest version includes support for an Active-Active cluster (note: I haven't tried that as yet).
Nova scheduler can run in multiple locations without issue, as can nova-api. nova-compute and nova-network (with multi_host) work directly on the hosting nodes. If you loose on of those nodes, you loose the VM's on it at the same time - no real way around that, but it limits the fault zone significantly from the original nova-network implementation. -joe On Sep 19, 2011, at 9:42 AM, Nelson Nahum wrote: > We would like to install Nova in HA mode, > > Anybody has experience doing that?
