First Claim
Patent Images
1. A method comprising:
- receiving fault information relating to a fault associated with an operation of guest software;
determining whether the fault information satisfies at least one filtering criterion; and
refraining from transitioning control to a virtual machine monitor (VMM) if the fault information satisfies the at least one filtering criterion.

Abstract
In one embodiment, fault information relating to a fault associated with the operation of guest software is received. Further, a determination is made as to whether the fault information satisfies one or more filtering criterion. If the determination is positive, control remains with the guest software and is not transferred to the virtual machine monitor (VMM).

11. A method comprising:
-
determining whether a fault associated with an operation of guest software requires a transition of control to a virtual machine monitor (VMM) using fault information relating to the fault and at least one control transfer filtering criterion; and
delivering the fault to the guest software if the fault information satisfies the at least one control transfer filtering criterion. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
