When scripts/vm/hypervisor/kvm/kvmvmactivity.sh is called with an incorrect file name, an error is printed which is then interpreted as output from the script.
When an incorrect file name is passed the script prints out:
stat: cannot stat ‘b51d7336-d964-44ee-be60-bf62783dabc’: No such file or directory
=====> DEAD <======
The KVMHAVMActivityChecker.java checkingHB() process is expecting just
=====> DEAD <======
but gets the unexpected error message and interprets the file as alive.
- All tests should pass on KVM, Simulator
- Add test cases covering FSM state transitions and actions

Host-HA offers investigation, fencing and recovery mechanisms for host that for
any reason are malfunctioning. It uses Activity and Health checks to determine
current host state based on which it may degrade a host or try to recover it. On
failing to recover it, it may try to fence the host.
The core feature is implemented in a hypervisor agnostic way, with two separate
implementations of the driver/provider for Simulator and KVM hypervisors. The
framework also allows for implementation of other hypervisor specific provider
implementation in future.
The Host-HA provider implementation for KVM hypervisor uses the out-of-band
management sub-system to issue IPMI calls to reset (recover) or poweroff (fence)
a host.
The Host-HA provider implementation for Simulator provides a means of testing
and validating the core framework implementation.
