Why is Virtual Server telling me that "hardware/bios/time_bytes" changed?

A couple of people have noticed strange entries in their event log for Virtual Server – like:

The setting “hardware/bios/time_bytes” for the virtual machine configuration “Test virtual machine” was changed.

These entries appear because Virtual Server creates an informational eventlog whenever a setting for a virtual machine is changed.  This will happen if the change is the result of a user action – or even if it is just the result of Virtual Server changing its own settings.  In the case of the above entry – whenever you turn off / save state / reset a virtual machine, Virtual Server stores the time that was in the BIOS.

Personally I usually filter out the informational events when looking at the Virtual Server log files and only look at warning and critical events.
