On a side note: There are not such problems when using OS virtualisation (as 
in Linux-VServer[1], for example) - run an ntpd on the 'host' and have the 
same time in all guests. It also has very little overhead. So if it's an 
option to use OS virtualisation instead of "real virtualisation", maybe you 
can save yourself the hassle with time jumping backwards.
