Thread-topic:	[PATCH 0/2] Simplified Virtual Periodic Timer Implementation

Hi,
The following patches add a simplified virtual periodic timer implementation, which in essence pins guest TSC with host TSC. User can use per-domain configration option to control whether it wil be used.

Could you please have a look and give some comments?

sim_xen.patch: Changes made to xen, which disables dynamicly adjusting guest tsc_offset according to number of injections of guest periodic timer interrupts and adds a hypercall to pass configration options from user space.

sim_config.patch User space changes. Parse option in domain configration file and pass it to hypervisor.

Best Regards
Haitao Shan
