> VMs with HA enabled, power back on if shutdown from guest OS
> ------------------------------------------------------------
>
> Key: CLOUDSTACK-10309
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10309
> Project: CloudStack
> Issue Type: Improvement
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Management Server
> Affects Versions: 4.9.0, 4.10.0.0
> Environment: KVM
> Reporter: Sean Lair
> Priority: Minor
>
> 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 Issue is being tied to a new 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* *onlin*e+, then
> it won't power it 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 (with 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.
