Abstract
A method for simulating a hardware failure in a virtualization environment includes determining a location of an instruction pointer for a particular operating system operating in the virtualization environment; determining an address of a memory location containing an invalid instruction; and writing the address of the memory location containing the invalid instruction in the location of the instruction pointer.
Claims13
A method for simulating a hardware failure in a virtualization environment, the method comprising:
- determining a location of an instruction pointer for a particular operating system operating in the virtualization environment;
- determining an address of a memory location containing an invalid instruction;
- and
- writing the address of the memory location containing the invalid instruction in the location of the instruction pointer.
A method for testing a partitionable computer simulating a hardware failure in a virtualization environment, the method comprising:
- partitioning the computer into one or more virtual machines including a first virtual machine;
- determining the operating system installed on the first virtual machine;
- determining a location of an instruction pointer for the operating system operating on the first virtual machine;
- determining an address of a memory location containing an invalid instruction for the operating system on the first virtual machine;
- and
- writing the address of the memory location containing the invalid instruction in the location of the instruction pointer.
The method ofclaim 12, wherein the address ofthe memory location containing the invalid instruction is the represented by a value of negative one.
Dependencies are inferred from the claim text.
