Hooks in time synchronization

[Christian G. <chr...@go...>]

Hi all,

I'm currently running several virtual machines on VMware ESXI 4.1 and am
wondering whether there is a possibility to explicitely steer the system
time (wall clock) of selected virtual machines instead of letting them
synchronize to VMware ESXI base system time.

So: are there hooks in the time synchronization module (vmsync ?) to dictate
a VM's wall clock such that dependent on the external time dictate module
the selected wall clock inside the VM runs faster or slower than (in general
asynchronous to) the base system time?

Why: want to run accelerated or slown down network emulations similiar to a
project called slicetime:

Any help or hints are highly appreciated!

Thanks & Best regards,

Chris.
