 The system disappeared from "ruptime", but wasn't down.  In the past
 this has indicated that the clock went backwards (which confuses the
 ruptime / rwho stuff).  What I usually do is log into the console, go
 into single user and umount the filesystems before destroying the DOMU
 (or if I am luckly a reboot, but that doesn't always work).  Upon doing
 a "umount -a" the following was printed on the console:
 
 [ 175409.0295886] WARNING: lwp 8442 (umount): negative runtime: (-1 + 0x857d0fb35b7fa2d0/2^64) sec
 [ 175409.0295886] WARNING: pid 8442 (umount): negative runtime; monotonic clock has gone backwards
 
 Before I did any of that I did a date and noticed that the clock was
 about 1 hour behind.  I personally don't think that this could have been
 due to anything gradually changing with the clock.
