question about sysenter
 

Hi; in (http://www.intel.com/technology/itj/...3-software.htm ) it’s declared that
Executions of SYSENTER by a guest application cause transitions to the VMM and not to the guest OS. The VMM must emulate every guest execution of SYSENTER.
It means that execution of sysenter instruction cause a VM Exit and transfer control to VMM to handle guest’s system calls. Please say me how VMM handles guest’s system calls?
Dose VMM uses guest system calls handler routines to handle guest’s system calls?
Sincerely u .
