We need to handle events with PIE_DISPATCHER type.
Could you please shed some more light on why we need this. I guess it fixes some problem, so more explanation could be useful.
If the configuration of the instance has been modified, for example added disk or network device, then hypervisor
sends event with prlIssuerType = PIE_DISPATCHER and EventType = PET_DSP_EVT_VM_CONFIG_CHANGED
We should handle this event in prlsdkHandleVmEvent function to update instance's XML config.
This was breaked by my commit c71f5f8cee3fe4078c3ab8aa7c46de7210b468c6
The only event of issuer type PIE_VIRTUAL_MACHINE is performace event, all
others events issuer type is PIE_VIRTUAL_MACHINE. I was miguided
by event names:
PET_DSP_EVT_VM_PERFSTATS
PET_DSP_EVT_VM_UNREGISTERED
So what are others?
Do not write error messages to log in case of unhandled event types.
Again, please explain why we shouldn't log them as errors if we return them as failure.
prlsdkHandleVmEvent is a common handler and it recieves many events.
We handle only part of them. In case we don't handle event, we return error code to a caller function,
which should make a decision whether to write error message to log.
This also restores behaviour before named commit.
