摘要： 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.

摘要： 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.

摘要： A first hypervisor uses a first version of a virtual-memory file system (VMemFS) suspends virtual machines. A second hypervisor uses a instance of the VMemFS, the version of which may be the same or different from the first version. The VMemFS is designed so that an instance of the same or a later version of the VMemFS can read and ingest information in memory written to memory by another instance of the VMemFS. Accordingly, the second hypervisor resumes the virtual machines, effecting an update or other swap of hypervisors with minimal interruption. In other examples, the swapped hypervisors support process containers or simply support virtual memory.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
