    Abstract: A file descriptor data structure is configured as a hierarchy of tables. File descriptors are stored as entries in tables that are at the bottom of the hierarchy. When a request to add a file descriptor is received and there are no more entries remaining in the file descriptor tables, the file descriptor data structure is extended by obtaining a lock on a variable containing a maximum number of file descriptors, adding the file descriptor to a new file descriptor table, updating entries in existing upper level tables of the hierarchy so that they point to the new file descriptor table, updating the variable containing the maximum number of file descriptors, and releasing the lock.

    Abstract: A hypervisor exchange, e.g., an upgrade, can include consolidating resident virtual machines into a single host virtual machine, exchanging an old hypervisor with a new (upgraded) hypervisor, and disassociating the virtual resident virtual machines by migrating them to the new hypervisor. The consolidating can involve migrating the resident virtual machines from the old hypervisor to a guest hypervisor on the host virtual machine. The exchange can involve: 1) suspending the host virtual machine before the exchange; and 2) resuming the host virtual machine after the exchange; or migrating the host virtual machine from a partition including the old hypervisor to a partition hosting the new hypervisor. Either way, an exchange (upgrade) is achieve without requiring a bandwidth consuming migration over a network to a standby machine.

    Abstract: A computer system mechanism is provided that restricts execution of binaries, such as applications, kernel modules, shared libraries, on the computing system to only those that have been installed by an approved mechanism. The approved mechanism acts as a single entry point on the computing for installing new binaries. Any change in file content or metadata taints an executable file and prevents execution by the kernel. Files copied over and not installed via, the approved mechanism will not be executed.

    Abstract: A method of remediating system services relies on a first dependency graph with super nodes, to each of which a set of system services are assigned, and second dependency graphs, each of which represents dependencies among the system services that are in one of the sets. The method includes the steps of: comparing an actual configuration state of the system services to a desired configuration state of the system services to identify configurations that are in drift; identifying system services corresponding to the configurations that are in drift; determining an order of updating configurations of the identified system services using the first and second dependency graphs; and applying the desired configurations of the identified system services in the order determined, wherein after the configurations of an identified system service are updated, the system service executes with the updated configurations.

    Abstract: A method of managing configurations of a plurality of system services, including a first system service and a second system service, in each of a plurality of hosts, wherein each of the hosts is configured with a virtualization software for supporting execution of virtual machines therein includes steps of: upon receiving an application programming interface (API) call to apply configurations of the system services defined in a desired configuration file to the system services, parsing the desired configuration file to identify a first configuration for the first system service and a second configuration for the second system service, and storing the first and second configurations in accordance with a configuration schema defined for the first and second system services, wherein the first system service executes with the stored first configuration applied thereto and the second system service executes with the stored second configuration applied thereto.

    Abstract: An example method of managing a lifecycle of virtualization software in a host is described. The method includes: obtaining, by an initiator in a current version of the virtualization software, a software installation bundle (SIB) from an image repository for a target version of the virtualization software, the SIB including a patcher; verifying, by the initiator, authenticity of the SIB; mounting at least one payload of the SIB in a root filesystem of the virtualization software, and initiating, by the initiator, the patcher in the at least one payload as mounted to perform at least one check operation.

    Abstract: A virtualized computing system includes a plurality of hosts, each of which is configured with a virtualization software for supporting execution of virtual machines therein. A method of managing a configuration of a system service in the virtualized computing system includes: upon receiving an API call to operate on a configuration object for the system service that is backed by a configuration schema of the system service, updating a database in accordance with the configuration schema to update or store the configuration of the system service, so that the system service executes with the configuration stored in the database.

    Abstract: A method of updating a desired state of a virtualization software for a cluster of hosts includes: in response to a notification of a change associated with the cluster, determining versions of a base image of the virtualization software that are compatible with the cluster; for each compatible version of the base image, determining versions of an add-on image of the virtualization software that are compatible with the compatible version of the base image and the cluster; presenting as a recommended image a complete image of the virtualization software, the complete image containing a first version of the base image that is compatible with the cluster and a first version of the add-on image that is compatible with the first version of the base image and the cluster; and upon acceptance of the recommended image, updating a software specification to include the recommended image.
