Hey Jafar, For HA to work on KVM, you need to configure each host with out-of-band management using ipmitool or Redfish. This is so Cloudstack can fence your nodes.
This covers the concept - https://docs.cloudstack.apache.org/en/latest/adminguide/reliability.html?highlight=fencing#ha-enabled-hosts Out-of-band documentation is here - https://docs.cloudstack.apache.org/en/latest/adminguide/hosts.html#out-of-band-management For details on how the feature works, check out the original design document - https://cwiki.apache.org/confluence/display/CLOUDSTACK/Host+HA -Si On Fri, Feb 10, 2023 at 12:32 PM Jafar Aghabalayev < [email protected]> wrote: > Hello Community, > > I have configured cluster with 2 KVM Hosts. > HA enabled for hosts, ha.tag attribute on global configuration is the same > as for ha.tag attribute for hosts.
