It was a mistake for me to say HA when referring to compute and
instances. Really I want to avoid a situation where one of my compute
hosts gives up the ghost, and all of the instances are offline until
someone reboots them on a different host. I would like them to
automatically reboot on a healthy compute node.

This looks like the kind of thing I'm searching for.
I'm seeing 3 components here, I'm assuming one goes on compute hosts and
one or both of the others go on the control nodes?
I don't believe anything goes on the compute nodes, no. I'm pretty sure
the Masakari API service and engine workers live on controller nodes.
Is there any documentation outlining the procedure for deploying
this? Will there be any problem running the Masakari API service on 2
machines simultaneously, sitting behind HAProxy?
Not sure. I'll leave it up to the Masakari developers to help out here.
I've added [masakari] topic to the subject line.
Best,
