>
> We could inject controlled faults in to simulated hypervisors, network
> elements, storage resources, system VM's and try out tests for testing the
> resiliency of CloudStack core.
> For example, we can have test case (that runs only for Simulator) where we
> instruct a simulated hypervisor resource to not to respond to ping from
> CloudStack. Expected result would be core to treat hypervisor host as
> disconnected and trigger HA enabled VM's.
> My initial thinking is to expose set of test API from simulator plug-in that
> would help inject transient/permanent/intermittent faults into simulated
> resources like
> - host that lost network connectivity with MS
> - delayed response to agent commands (simulate overloaded hypervisor stacks
> like XAPI, vCenter) and long running tasks like snapshots
> - non responding edge service VM's
> need to think little more on the failure categories and points, and best
> abstract them test API so that can enable flexible and rich resilience tests.
