> VMs with HA enabled, power back on if shutdown from guest OS
> ------------------------------------------------------------
>                 Key: CLOUDSTACK-10309
>                 URL:
>             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,
>         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.
