I ran some tests with this propose. But I'm not sure about my environment. I
couldn't see my kvm agent stop at any point.
anyway, I managed to verify that the behavior of the externalized parameter
is in accordance with what was proposed.
forcing my heartbeat timeout on two kvm hosts it's possible to see that the
ones without the parameter
`reboot.host.and.alert.management.on.heartbeat.timeout=false` will log the
mensage `failed: timeout; stopping cloudstack-agent.`
**Kvm-nd01**
```
heartbeat.update.timeout=10
reboot.host.and.alert.management.on.heartbeat.timeout=true
```
```
