Abstract: The disclosure provides an approach for dynamically reprogramming network and network infrastructure in response to VM mobility. The approach provides a hypervisor layer that can observe changes in VM-host relationships and reprogram the associated network and network infrastructure to maintain network communication. The hypervisor layer notifies a controller of a data center to migrate an ENI of the migrated VM to the same destination host as the migrated VM, in response to VM migration.

Abstract: Exemplary methods, apparatuses, and systems include a first input/output (I/O) filter receiving, from a first filter module within a virtualization stack of a host computer, an input/output (I/O) request originated by a virtual machine and directed to a first virtual disk. The first I/O filter determines to redirect the I/O request to a second virtual disk and, in response, forwards the I/O request to a second I/O filter associated with the second virtual disk. The first I/O filter is a part of a first instance of a filter framework within the host computer and the second I/O filter is part of a second, separate instance of the filter framework.

Abstract: Techniques are disclosed for filtering input/output (I/O) requests in a virtualized computing environment. In some embodiments, a system stores first data in a page of memory, where after the first data is stored in the page of memory, the page of memory is free for allocation to a first memory consumer (e.g., an I/O filter instantiated in a virtualization layer of the virtualized computing environment) and a second memory consumer. The first memory consumer retains a reference to the page of memory. The first memory consumer receives a data request from a virtual computing instance. Based on the data request, the first memory consumer retrieves the first data using the reference to the page of memory. After retrieving the first data, the system returns the first data to the virtual computing instance. While the first memory consumer has the reference to the page of memory, the page of memory can be allocated to the second memory consumer without notifying the first memory consumer.

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: The present disclosure provides techniques for managing a cache of a computer system using a cache management data structure. The cache management data structure includes a cold queue, a ghost queue, and a hot queue. The techniques herein improve the functioning of the computer because management of the cache management data structure can be performed in parallel with multiple cores or multiple processors, because a sequential scan will only pollute (i.e., add unimportant memory pages) cold queue, and to an extent, ghost queue, but not hot queue, and also because the cache management data structure has lower memory requirements and lower CPU overhead on cache hit than some prior art algorithms.

Abstract: The disclosure provides an approach for performing an operation by a first process on behalf of a second process, the method comprising: obtaining, by the first process, a memory handle from the second process, wherein the memory handle allows access, by the first process, to at least some of the address space of the second process; dividing the address space of the memory handle into a plurality of sections; receiving, by the first process, a request from the second process to perform an operation; determining, by the first process, a section of the plurality of sections that is to be mapped from the address space of the memory handle to the address space of the first process for the performance of the operation by the first process; mapping the section from the address space of the memory handle to the address space of the first process; and performing the operation by the first process on behalf of the second process.

Abstract: The disclosure provides an approach for dynamically reprogramming network and network infrastructure in response to VM mobility. The approach provides a hypervisor layer that can observe changes in VM-host relationships and reprogram the associated network and network infrastructure to maintain network communication. The hypervisor layer notifies an elastic network interface of a new IP address to include within its whitelist in response to VM migration to that elastic network interface.

Abstract: A dynamic content disk for a virtual computing instance is created as a thinly-provisioned virtual disk having a file system that is synthesized in accordance with a set of applications that are provisioned for a virtual machine (VM). To limit the allocated size of the dynamic content disk, a filter is attached to the dynamic content disk to intercept input-output operations (IOs) directed to the dynamic content disk and convert them to IOs directed to an application virtual disk that stores the actual files of the applications that are provisioned for the VM. The application virtual disk may be stored on different back-ends, such as storage area network (SAN), network file system, virtual SAN, cloud storage, or local storage.

Abstract: A method for processing a read request comprises intercepting a read request that includes a logical block address (LBA) of the storage device by an IO filter driver and retrieving a disk identifier (ID) associated with the LBA from a metadata file associated with the storage device. The method further comprises sending the LBA and the disk ID to a daemon configured to read and write to a cache. If the daemon returns cached data associated with the LBA and the disk ID, the method returns the cached data in response to the read request. If the daemon does not return cached data associated with the LBA and the disk ID, the method transmits the read request to the storage device.
Abstract translation: 一种用于处理读取请求的方法包括：通过IO过滤器驱动程序拦截包含存储设备的逻辑块地址（LBA）的读取请求，并从与存储器相关联的元数据文件中检索与LBA相关联的磁盘标识符（ID） 设备。 该方法还包括将LBA和盘ID发送到被配置为读取和写入高速缓存的守护程序。 如果守护程序返回与LBA和磁盘ID相关联的缓存数据，则该方法将响应读取请求返回缓存的数据。 如果守护程序不返回与LBA和磁盘ID相关联的缓存数据，则该方法将读请求发送到存储设备。

Abstract: A method for opening a virtual disk comprises reading information from a metadata file that identifies the current owner of the virtual disk. The method further includes sending a release request to the current owner of the virtual disk to release the virtual disk, writing information to the metadata file identifying the new owner, and then opening the virtual disk.
