Abstract
A system and methods are disclosed for testing guest firmware in virtualized computer systems. In accordance with one embodiment, a hypervisor executed by a processing device infers that firmware has created a system table in a portion of memory of a virtual machine. In response to the inferring, the hypervisor locates the system table and executes one or more commands to test the system table.
Claims20
A method comprising:
- inferring, by a processing device executing a hypervisor, that firmware has created a system table in a portion of memory of a virtual machine;
- locating by the processing device executing the hypervisor, in response to the inferring, the system table;
- and
- executing, by the processing device executing the hypervisor, one or more commands to test the system table without participation from a guest operating system located on the virtual machine.
1 more element
An apparatus comprising:
- a memory to store a virtual machine;
- and
- a processing device operatively coupled to the memory, the processing device to execute a hypervisor to:
- infer that firmware has created a system table in a portion of the memory associated with the virtual machine,
- locate, in response to the inferring, the system table, and
- execute one or more commands to test the system table without participation from a guest operating system located on the virtual machine.
3 more elements
A non-transitory computer readable storage medium, having instructions stored therein, which when executed, cause a processing device executing a hypervisor to:
- infer, by the processing device executing the hypervisor, that firmware has created a system table in a portion of memory of a virtual machine;
- locate by the processing device executing the hypervisor the system table;
- and
- execute, by the processing device executing the hypervisor, one or more commands to test the system table without participation from a guest operating system located on the virtual machine.
