Hi Eric, (1) "virtual machine" is bug. This need to be corrected as physical machine or hypervisor. Masakari host is a physical host/hypervisor. I will correct this.
(2) Not through masakari APIs. You have to add metadata key 'HA_Enabled=True' to each VM by using nova API. Masakeri monitors check for failures and send notification to masakari API if detected any failure (i.e host, VM or process failures). In host failure (hypervisor down) scenario, Masakari engine get the VM list on that hypervisor and start evacuate VMs. Operator can configure masakari to evacuate all VMs or only the VMs with the metadata key 'HA_Enabled=True. Please see the config file  section [host_failure] for more details. Let me know if you need more info on this.  https://docs.openstack.org/masakari/latest/sample_config.html --- Regards, Sampath On Sun, Oct 7, 2018 at 8:55 AM Eric K <ekcs.openst...@gmail.com> wrote: > Hi all, I'm working on a potential integration between masakari and > congress.
