Slair1 opened a new pull request #2473: CLOUDSTACK-10309 Add option on if to VM HA power-on a OOB-shut-off-VM URL: https://github.com/apache/cloudstack/pull/2473 When a user shuts down their VM from the guest OS (and VM HA is enabled), the VM just powers itself back on. Our environment is on KVM hosts. CloudStack does not know the difference between a VM failing or being shutdown from within the guest OS. This is a major pain point for all our users - especially since they don't pay for VMs when they are shutoff. It is not intuitive for end-users to understand why they can't shutdown VMs from within the guest OS. Especially when they all come from (non-cloudstack) VMware and Hyper-V environments where this is not an issue. However, if a host fails, we need VM HA to still work. This PR that creates a configuration option "ha.vm.restart.hostup". With this option set to false, if CloudStack sees a VM shutdown out-of-band, but the host it was on is still *online*, then it won't power the VM back on. The logic is that since the host is online, it was most likely shutdown from the guest OS. For when a host actually fails, standard VM HA logic takes over and powers on VMs (if they have VM HA enabled) if the host they were on fails. If that "ha.vm.restart.hostup" option is true (the default to match current functionality), it works like always, and even in-guest shutdowns of VMs causes CloudStack to power back on the VM.
