From code it seems to be getting updated and DB also suggests that. It will
not be updated if there is no power change for
MAX_CONSECUTIVE_SAME_STATE_UPDATE_COUNT. But that is to reduce DB transactions
and will not create issues as it is updated if there is change in power state.
Grace period can be increased by increasing ping interval. By default it is
60 seconds. You can increase it to 90 or 120 seconds to increase the grace
period.
Code which is doing update
for (Map.Entry<Long, VirtualMachine.PowerState> entry :
translatedInfo.entrySet()) {
if (s_logger.isDebugEnabled())
s_logger.debug("VM state report. host: " + hostId + ", vm
id: " + entry.getKey() + ", power state: " + entry.getValue());
if (_instanceDao.updatePowerState(entry.getKey(), hostId,
entry.getValue())) {
if (s_logger.isDebugEnabled())
s_logger.debug("VM state report is updated. host: " +
hostId + ", vm id: " + entry.getKey() + ", power state: " + entry.getValue());
