  • Patent number: 12014199
    Abstract: Systems and methods for processing virtual machine I/O requests by virtualization extension modules. An example method comprises receiving, by a virtual machine monitor (VMM) mining on a host computer system, a request initiated by a virtual machine managed by the VMM; processing the request by a VMM extension module identified by one or more parameters of the request; invoking, by the VMM extension module, an application programming interface (API) exported by the VMM to perform an action identified by the request; and resuming execution of the virtual machine.

  • Patent number: 11995441
    Abstract: Systems and methods for instruction decoding using hash tables. An example method of constructing a decoding tree comprises: generating an aggregated vector of differentiating bit scores representing at least a subset of a set of processor instructions; identifying, based on the aggregated vector of differentiating bit scores, one or more opcode bit positions; and constructing a hash table implementing a current level of a decoding tree representing the subset of the set of processor instructions, wherein the hash table is indexed by one or more opcode bits identified by the one or more opcode bit positions.

  • Patent number: 11934862
    Abstract: Virtual computer systems (virtual machines) have become increasingly common with the evolution of virtualization technology, cloud computing, etc. However, as a virtual machine and its associated guest operating system seek to execute and/or access a page of memory through synchronous processes execution of the virtual processor associated with the virtual processing is blocked until the page of memory is locked and available. Accordingly, time is wasted on calls waiting for physical page availability thereby reducing utilization of the host machine and virtual machine respectively. To address this an asynchronous virtual machine environment is established allowing the virtual machine or physical machine to handle additional operations whilst waiting for physical page availability.

  • Patent number: 11861390
    Abstract: A processing device in a host computer system receives an instruction to write data to a storage device coupled to the host computer system and store a copy of the data in a cache of the host computer system. The processing device initiates a write operation to write the data from the cache to the storage device and detects that the storage device is disconnected from the host computer system during execution of the write operation. In response to detecting that the storage device is disconnected, the processing device may suspend execution of at least one of a virtual machine or a process that issued the first instruction. After determining that the storage device is reconnected to the host computer system, the processing device can resume the write operation to continue writing the data from the cache to the storage device.

  • Patent number: 11816347
    Abstract: Systems and methods for creating virtual machine snapshots. An example method comprises: receiving a request to create a snapshot of a virtual machine running on a host computer system; protecting from modification a plurality of virtual memory pages of the virtual machine; responsive to detecting an attempt to modify a virtual memory page of the plurality of memory pages, copying the virtual memory page to a queue residing in a random access memory (RAM) of the host computer system; making the virtual memory page writable; retrieving the virtual memory page from the queue; writing the virtual memory page to a disk of the host computer system; and responsive to exhausting the queue, completing creation of the snapshot of the virtual machine.

  • Patent number: 11700313
    Abstract: Disclosed are systems and methods for seamlessly redirecting network data between a client and a remote server. In one exemplary aspect, the method comprises receiving, at a remote server, the network data via a first remote desktop protocol (RDP) channel, wherein the network data is encapsulated and transmitted by a client device configured to communicate with the remote server. The method further comprises replacing a MAC address listed in the network data with a MAC address of a logical network adapter on the remote server, and placing received network packets into a network driver of the logical network adapter, wherein the logical network adapter transfers received data in an operating system of the remote server such that a server-side application on the remote server receives network packets from the client device.

  • Patent number: 11256534
    Abstract: Disclosed are systems and methods for executing system calls in a virtualized environment. A method includes executing, on a host, a host process corresponding to a guest process executing within a virtual machine and having an associated guest-process virtual address space, the host process having an associated host-process virtual address space. The method also includes mapping the host-process virtual address space and the guest-process virtual address space to a host physical memory, trapping a system call invoked by the guest process, and performing the trapped system call using the host process, wherein state changes in the host-process virtual address space caused by the trapped system call are reflected in the guest-process virtual address space. The method further includes causing execution of the guest process to be resumed after performing the trapped system call.
