Abstract: In some examples, a storage medium stores information relating to reset ports associated with respective virtual machines (VMs) of a plurality of VMs. A controller detects, based on the information, an activation of a first reset port associated with a first VM of the plurality of VMs. In response to the detecting, the controller provides an indication of the activation of the first reset port to a hypervisor that is separate from the controller, the indication to cause the hypervisor to reset the first VM.

Abstract: In some examples, a device includes a memory controller to, during a power-on process of the device: read encrypted data from a nonvolatile memory, decrypt, using a first key, the encrypted data to produce decrypted data, encrypt, using a second key different from the first key produced as part of rekeying, the decrypted data to produce new encrypted data, and write the new encrypted data to the nonvolatile memory. A power-on code is to prevent booting of the device until all data in the nonvolatile memory has been encrypted using the second key.

Abstract: A supervisor provides a plurality of virtual nodes. A storage medium stores a plurality of information elements. A controller, which is separate from the supervisor, provides a plurality of virtual precision time protocol (PTP) clock devices. Each virtual PTP clock device corresponds to an information element. The controller uses the information element corresponding to a given virtual precision time protocol clock device to provide a precision time protocol-based time for the given virtual precision time protocol clock device.

Abstract: A non-transitory machine-readable storage medium stores instructions that, when executed by the machine, cause the machine to provide a firewall interface between a plurality of registers of a controller and a host interface of the controller. Providing the firewall interface includes programming the firewall interface with a plurality of firewall rules. The registers are to control functions that are performed by the controller; and the plurality of firewall rules control whether requests to access the plurality of registers are denied, allowed or modified based on features of the request.

Abstract: In some examples, a storage medium stores a plurality of information elements that relate to corresponding virtual trusted platform module (TPM) interfaces, where each respective information element of the plurality of information elements corresponds to a respective virtual machine (VM). A controller provides virtual TPMs for respective security operations. A processor resource executes the VMs to use the information elements to access the corresponding virtual TPM interfaces to invoke the security operations of the virtual TPMs, where a first VM is to access a first virtual TPM interface of the virtual TPM interfaces to request that a security operation of a respective virtual TPM be performed.

Abstract: In some examples, a storage medium to stores information indicating address locations of virtual serial ports, where the virtual serial ports are associated with respective virtual machines (VMs). A controller that is separate from a hypervisor is to detect, based on the information, an access of a first virtual serial port associated with a first VM of the plurality of VMs, and communicate data between the first VM and another entity through the first virtual serial port.

Abstract: An example apparatus comprises a drive carrier assembly which may include a memory device, and an energy storage device having at least a portion thereof encased in a housing. In some examples, the apparatus may include a printed circuit assembly to detect a power failure of a host computing device. The printed circuit assembly, may have a first portion coupled to the energy storage device and a second portion coupled to a backplane of the host computing device.
