Not so sure but links refers to HA in RBD primary storage and they mention VM HA that is more related to
https://docs.cloudstack.apache.org/en/latest/adminguide/reliability.html?highlight=HA#ha-enabled-virtual-machines HA-Enabled Virtual Machines The user can specify a virtual machine as HA-enabled. By default, all virtual router VMs and Elastic Load Balancing VMs are automatically configured as HA-enabled. When an HA-enabled VM crashes, CloudStack detects the crash and restarts the VM automatically within the same Availability Zone. HA is never performed across different Availability Zones. CloudStack has a conservative policy towards restarting VMs and ensures that there will never be two instances of the same VM running at the same time. The Management Server attempts to start the VM on another Host in the same cluster. HA features work with iSCSI or NFS primary storage. HA with local storage is not supported. Is there any PR related to this?

There is a PR that provides a solution to have HA for RBD, but it's not merged yet - https://github.com/apache/cloudstack/pull/5862. I hope the links below will help you https://docs.cloudstack.apache.org/en/latest/adminguide/reliability.html#ha-enabled-hosts https://cwiki.apache.org/confluence/display/CLOUDSTACK/Out-of-band+Management+for+CloudStack https://www.shapeblue.com/host-ha-for-kvm-hosts-in-cloudstack/#Host-HA_on_KVM_host Best regards, Slavka On Fri, Dec 2, 2022 at 9:02 AM Ranjit Jadhav <ranjeet.jad...@gmail.com> wrote: > Hello Guys, > > We are also struggling with this HA thing any guidance will be highly > appreciated. > > Regards, > Ranjit > > On Thu, 1 Dec 2022 at 20:50, pspa...@hotmail.com <pspa...@hotmail.com> > wrote: > > > Hi, > > I have build new infra with Ceph storage everything working well. > > But VMs HA not working.
