Hi Tushar,
I followed the documentation to set up the masakari monitors, after I
installed the masakari API. None of the monitor services seem to work. I keep
getting an error: "AttributeError: 'module' object has no attribute 'URI'&qu

There is no HA behaviour for compute nodes.
You are referring to HA of workloads running on compute nodes, not HA of
compute nodes themselves.
It was a mistake for me to say HA when referring to compute and instances.
Really I want to avoid a

Thank you very much for the information. Just for clarification, when you say
reserved hosts, do you mean that I must keep unloaded virtualization hosts in
reserve? Or can Masakari move instances from a downed host to an already loaded
host that has open capacity?
Take this with a grain of salt because we're using the original version
before the project moved under the Big Tent and I'm not sure how much it's
evolved since then. I assume the basic functions are the same though.
You're correct; Corosync and Pacemaker are used to determine if a compute

I'm vaguely familiar with Pacemaker/Corosync, as I'm using it with HAProxy on
my controller nodes. I'm assuming in this instance that you use Pacemaker on
your compute hosts so masakari can detect host outages? If possible could you
go into more detail about the configuration? I would like to

We're using the original Masakari project for this and it works really
well. In fact just last week we lost a compute node and all of VM's were
successfully migrated to a reserve host in under 5 minutes. It's a really
nice feeling when your infrastructure heals itself before you even get a
chance

I am working on setting up Openstack for HA and one of the last orders of

that will automatically evacuate instances from a downed or failed compute
host, and automatically reboot them on their new host? I'm curious
