[Openstack] HA Compute & Instance Evacuation
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'"
Here is the full output: http://paste.openstack.org/show/720761/
Are you aware of what causes the issue? Can you provide any example configs
for a working masakari setup?
