In one embodiment, a method includes integrating a charging pad into a powered device having a power supply, where the powered device is at least one of a monitor and a keyboard. The method includes configuring the charging pad to receive a first chargeable device in a charging position relative to the charging pad. The method further includes configuring the charging pad to deliver an electrical charge from the power supply to the first chargeable device when the chargeable device is in the charging position.

A system for providing a steganographic message to a hypervisor may include a memory having computer readable instructions and one or more processors for executing the computer readable instructions. The computer readable instructions may include identifying a plurality of selected bits of usage data of a virtual machine. Further according to the computer readable instructions, a desired message may be encoded as a steganographic message stored in the plurality of selected bits in the usage data. Encoding the desired message may include manipulating one or more resources of the virtual machine to cause a change in the plurality of selected bits in the usage data. The usage data may be provided to the hypervisor, and the steganographic message may be observable in the usage data.

Steganographic message passing between a virtual machine and a hypervisor

A computer-implemented method may include identifying a plurality of selected bits of usage data of a virtual machine. A desired message may be encoded, by a computer processor, as a steganographic message stored in the plurality of selected bits in the usage data. Encoding the desired message may include manipulating one or more resources of the virtual machine to cause a change in the plurality of selected bits in the usage data. The usage data may be provided to the hypervisor, and the steganographic message may be observable in the usage data.

Virtual machine guest migration overcommit is supported by providing a virtual machine with an unschedulable resource that is not available for system scheduling. The unschedulable resource may, but need not, be provided in the form of a memory buffer, or one or more network resources, or one or more resources that are accessible from a network. The unschedulable resource is utilized in one or more domains to temporarily conceal one or more user environments that do not fit into a set of currently available resources, such that the one or more temporarily concealed user environments are not terminated or paged out.

Method, computer program product, and hardware product for supporting virtual machine guest migration overcommit

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.
