AFAIR, the TimerState captures the amount of host nsec/cycles that the VM has been stopped for since the last VM stop/start pair. > As per Lluis' reply, this structure is keeping track of the time when > the VM started. Can you determine this from the variables that are > part of this structure? Determine what? The amount of host nsec/cycles or the amount of guest nsec/cycles? The former cannot be directly obtained unless you aggregate the intermediate values in TimerState (although you're already able to get that information from the OS). The latter depends under which configuration you're executing (i.e., use_icount).
