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.
