In an approach a computer receives a first request from a metadata service to store metadata for a virtual machine (VM). The computer validates the metadata service. The computer stores the metadata for the VM in response to the validation being successful. The computer receives a second request from the VM for the metadata. The computer sends the metadata to the VM.

Metadata service provisioning in a cloud environment

A method, computer program product, and system includes a processing circuit(s) allocating a page of system memory address space to a device. The allocating includes the processing circuits(s) obtaining base address registers of the device in a bus and determining a portion of the page of the system memory address space to allocate to the base address registers. The processing circuits(s) sorts the base address registers, in a descending order, according to their alignments and adds sizes of the sorted base address registers to determine the portion of the page. The processing circuit(s) determines a remainder of the page: a difference between a size of the page and the portion of the page. The processing circuit(s) requests a virtual resource of a size equal to the remainder and allocates the page to the sorted base address registers and to the virtual resource.

Allocating address space

Methods, computer program products, and systems are presented. The method computer program products, and systems can include, for instance: collecting logging data generated by operation of a distributed computing system that is used by a plurality of tenants; storing the logging data as a plurality of files stored in a multi tier, shared volume storage system, with the storage of the logging data as a plurality of files including: dividing the plurality of files among and between a plurality of shared volume data structures, and organizing each shared volume data structure of the plurality of shared volume data structures according to a plurality of tiers; for each given file of the plurality of files; and mapping, by a domain agent and in a mapping table data structure, an association between the given file and the shared volume data structure in which the given file is stored.

Shared volume based centralized logging

A computer-implemented method comprising a processor providing a Multiple Address Resolution Protocol (MARP) message, wherein the MARP message comprises multiple Media Access Control (MAC) addresses associated with an Internet Protocol (IP) address.

Multiple link layer address resolution protocol (ARP)

Embodiments of the present invention disclose a method, computer program product, and system for allocating memory. A computer receives a request for memory to be allocated to a computer node and determines if the allocation request needs to be carried out on a cluster level, a server rack level, or on a server level. The computer retrieves a memory policy associated with the determined level the allocation request needs to be carried out on from a memory policy database and determines how much available memory may be allocated and if there enough available memory to meet the request. The computer reallocates the available memory to address the received the received request based on the retrieved memory policy.

A digital credential is generated for a user device. The digital credential is transmitted to the user device via an optical wireless communication access point (OWC AP). The user device is located in a coverage area of the OWC AP. The digital credential is provided to a wireless local area network (WLAN AP) associated with the OWC AP for authentication of a request from the user device to access the WLAN.

Authentication for wireless local area networks

Implementations of the present disclosure relate to methods, systems and products for access control. In one implementation, a computer-implemented method is proposed. According to the method, a token for accessing an object is received from a terminal device via a communication channel, where the communication channel is built based on a Light Fidelity connection which is deployed within a restrictive area. A validity of the received token is determined. An access to the object is controlled based on the validity of the received token.

Token-based access control

Recognizing and utilizing dial patterns of a mobile electronic device includes detecting an input sequence, recording the input sequence when the input sequence is detected, and determining whether the input sequence is a reoccurring pattern. If the input sequence is a reoccurring pattern, the input sequence is stored in a repository as a dial pattern that is assigned to a call number. When a call number is detected in a dialer, the dial pattern is then presented to the dialer, and the dial pattern is dialed upon establishing a connection with the call number.

Dial pattern recognition on mobile electronic devices

According to embodiments of the present invention, a method, a device and a computer program product for quick deployment of multiple virtual machines are provided. The method comprises mounting a centralized storage volume on a host in response to boot-up of a virtual machine on the host. The method further comprises obtaining unique information assigned to the virtual machine. In addition, the method comprises retrieving public and private configuration for the virtual machine from the centralized storage volume based on the obtained unique information, the public and private configuration being applied in the boot-up of the virtual machine on the host.

Deployment of virtual machines

A computer system includes program instructions to generate a first virtual keypad for entry of a first portion of a password, wherein the first portion includes a first value and a second value. The program instructions receive the first portion, wherein the first portion includes a first number of keys selected equal to the first value and the second value present in the first number of keys selected. The program instructions generate a second virtual keypad for entry of a second portion, wherein the second portion includes a third and a fourth value. The program instructions receive the second portion, wherein the second portion includes a second number of keys selected equal to the third value and the fourth value present in the second number of keys selected. The program instructions determine to grant a user access to an account associated with the account password.
