VMWare-based ones.

The main problem was with the management of the system clock, where VMWare
was making the clock slower and then make a "jump" to compensate the
slowiness. So, I got a lot of line "new modification with older timer
value" (can't remember the precise log line, though).

I had to switch to plain physical server (which was my target by then).
