Thanks Tim.

 

I see HYPERVISOR_shared_info struct exported in xen.h. That means it common to all the VMs and hence can be used across all VM for time keeping ? (Not sure though).

 

But looking at the shared_info_t definition, it looks like per VM structure.

shared_info can also be accessed via start_info which seems like a per VM structure.

 

Can someone  through light on it.
 

Thanks,

Maulik.

This section of the interface manual explains the various time mechanisms:
