What version of DAHDI are you using?  If you're using a relatively recent version (2.2.0+) dahdi_dummy works better on virtual machines because it uses the wall time to adjust itself as opposed to just assuming it's going to be called at a fixed interval.  But, one issue with this is that if the host machine is unable to keep accurate wall time then dahdi_dummy can be confused about how much time is really passing.  The big jumps in accuracy make me think that NTP may be adjusting the host clock in several second increments?

The firewall changes aren't interfering with NTP or anything like that are they?

Just a thought...
