I have no idea.  Perhaps I misunderstood what the ntpd man page
referred to as a panic.

If it is not ntpd then I still need to discover some way of ensuring
that all the KVM guests that were active at the time of a power
failure automatically come back on line when the KVM host system
starts up.  I cannot find any reference to how this is done.

Are there any recommended solutions?  These systems are on UPS already
but the power failure duration exceeded the endurance of the the UPS.
