The virtual guest is Centos 5.4 based with dovecot 1.2.8 (at first we also tried with the original 1.0.7 (?) dovecot shipped with Centos).
I wrote "alleged time shift" because there is no timeshift whatsoever, or at least I don't notice it anywhere else.
ntp is - of course ;-) - up and running and no other applications have time troubles and I've even disabled the local clock as a time reference.
Of course you know not to use ntp on VMs, only on the host, right?

heh, ok, ship hit an sunk :-)
I was absolutely not aware of a "clocksource" kernel parameter, what a weird thing ...
Revent kernels should be able to keep the VM time synced using kvmclock clocksource...
So I'll give clocksource=acpi_pm a chance and see how it turns out ...
So for the sake of other peoples' nerves also facing this problem, the solution was to add "divider=10" as a kernel boot parameter.
There is an good post about this problem here:

and this also leads to this document for VMWare giving an indication of what the suggested parameters for various distributions are:
