VM status only updated at 12 hour intervals

Apologies if this is not the right forum for this question.

How is the state of a VM updated? It doesn't appear that anythin updates it outside of modeling, which doesn't seem like the correct thing. Shouldn't some other process update the state of a virtual machine or other component?

You're right about that. The VM state property is only updated during modeling, which will only occur at 12 hour intervals by default. However, the CloudStack alerts and events are polled on a 1 minute interval and will associated events and alerts to VMs if that's what they're applicable to. This will be reflected in the VMs event-based status.

This discrepancy between the modeled state property and status based on events probably should be cleared up either by polling for status of resources like VMs on that same 1 minute interval, or updating resource modeled status based on certain types of events occurring. The first option sounds like it would be easier and less prone to synchronization problems.
