Open Stack

Hello,

I am investigating various high availability options for a pending
deploy of open stack.  One of the obvious services to make resilient is
the mq service.  We're going to be using rabbitmq, and we'll most likely
have N of them in a standard rabbit mq cluster behind a load balancer
configured as active/passive.  One of the obvious improvements on this
would be to use mirrored queues to protect against message loss as well
as service downtime.

Are there recommended ways of doing this?  I see that I can use durable
queues, which might work around the problems of openstack checking queue
parameters on reconnect, but it seems a shame there's not an obvious way
to do this out of the box.  Unless I'm missing something?

Cheers,
