Abstract
An implementation may include a virtual trusted runtime BIOS managed by the virtual machine monitor. A replacement portion of the virtual trusted runtime BIOS may be included. A router can replace an address to a resource of the virtual trusted runtime BIOS with the address to the resource of the replacement portion of the virtual trusted runtime BIOS.
Claims20
A computing system comprising:
- hardware;
- a virtual machine monitor;
- a virtual trusted runtime BIOS managed by the virtual machine monitor;
- a replacement portion of the virtual trusted runtime BIOS, the replacement portion including a replacement resource for a first resource of the virtual trusted runtime BIOS;
- and
- a router,
- wherein the virtual machine monitor is to receive an access request including a first address to the first resource of the virtual trusted runtime BIOS, and to determine whether to redirect the access request to the replacement portion,
- wherein the router is to, in response to a determination to redirect the access request to the replacement portion, replace, in the access request, the first address to the first resource of the virtual trusted runtime BIOS with a second address to the replacement resource of the replacement portion.

A method comprising:
- managing a virtual trusted runtime BIOS;
- managing a replacement portion of the virtual trusted runtime BIOS, the replacement portion including a replacement resource for a first resource of the virtual trusted runtime BIOS;
- receiving an access request for the first resource of the virtual trusted runtime BIOS, the access request including a first address to the first resource;
- determining, by a virtual machine monitor, whether to redirect the access request to the replacement portion;
- and
- in response to a determination to redirect the access request to the replacement portion, replacing in the access request, with a router, the first address to the first resource of the virtual trusted runtime BIOS with a second address to the replacement resource of the replacement portion.

A computer readable medium comprising code that when executed by a processor causes a computing device to:
- manage a virtual trusted runtime BIOS;
- manage a replacement portion of the virtual trusted runtime BIOS, the replacement portion including a replacement resource for a first resource of the virtual trusted runtime BIOS;
- receive an access request for the first resource of the virtual trusted runtime BIOS, the access request including a first address to the first resource;
- determine, by a virtual machine monitor, whether to redirect the access request to the replacement portion;
- and
- in response to a determination to redirect the access request to the replacement portion, replace, in the access request, using a router, the first address to the first resource of the virtual trusted runtime BIOS with a second address to the replacement resource of the replacement portion of the virtual trusted runtime BIOS,
- wherein the computer readable medium is non-transitory.
