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).
Claims30
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.
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.
A system comprising:
- a memory having stored therein guest software;
- and
- a processor, coupled to the memory, to execute the guest software, to determine whether fault information relating to a fault associated with an operation of the guest software satisfies at least one filtering criterion, and to refrain from transitioning control to a virtual machine monitor (VMM) if the fault information satisfies the at least one filtering criterion.
