Patent number: 11888935Abstract: A cloud-based data protection service is disclosed. In an embodiment, the data protection service may support backup of data sets from one or more sites associated with one or more organizations. In an embodiment, deduplication of backup data across multiple sites of an organization and/or multiple sites associated with different organizations may be supported. In an embodiment, backup data may be post-processed in the cloud to insert fingerprints corresponding to data blocks that did not change since a previous backup was performed, to scan the backup for security threats such as viruses, other malware, personally identifiable information, etc. In an embodiment, restore may be supported from the cloud, where restore blocks may be larger than backup data blocks. In another embodiment, restore may be based on blocks that have changed since the most recent backup (or a user-selected backup).Type: GrantFiled: April 23, 2020Date of Patent: January 30, 2024Assignee: Clumio, Inc.Inventors: Lawrence Jaemyung Chang, Daniel Michael Hecht, Woon Ho Jung, Poojan Kumar, Amber Palekar, Hung Hing Anthony Pang, Kaustubh Sambhaji Patil, Rishabh Sharma

Networking stack of virtualization software configured to support latency sensitive virtual machines
Patent number: 10860356Abstract: A host computer has a plurality of containers including a first container executing therein, where the host also includes a physical network interface controller (NIC). A packet handling interrupt is detected upon receipt of a first data packet associated with the first container. If the first virtual machine is latency sensitive, then the packet handling interrupt is processed. If the first virtual machine is not latency sensitive, then the first data packet is queued and and processing of the packet handling interrupt is delayed.Type: GrantFiled: July 10, 2017Date of Patent: December 8, 2020Assignee: VMware, Inc.Inventors: Haoqiang Zheng, Lenin Singaravelu, Shilpi Agarwal, Daniel Michael Hecht, Garrett Smith -

Patent number: 10452417Abstract: Methods, apparatus, and articles of manufacture to virtualize performance counters are disclosed. An example method includes dividing performance events to be counted into a plurality of classes; assigning a first virtual performance counter of a virtual machine to a first performance event type in a first one of the classes; assigning a second virtual performance counter of the virtual machine to a second performance event type in a second one of the classes different from the first class; incrementing the first virtual performance counter in response to a first occurrence of the first performance event type during direct execution of guest instructions by the virtual machine; and not incrementing the first virtual performance counter in response to a second occurrence of the first performance event type during execution of emulated instructions by a hypervisor on behalf of the virtual machine.Type: GrantFiled: May 26, 2015Date of Patent: October 22, 2019Assignee: VMWARE, INC.Inventors: Benjamin Charles Serebrin, Daniel Michael Hecht

Patent number: 10073711Abstract: A host computer has a virtualization software that supports execution of a plurality of virtual machines, where the virtualization software includes a virtual machine monitor for each of the virtual machines, and where each virtual machine monitor emulates a virtual central processing unit (CPU) for a corresponding virtual machine. A virtual machine monitor halts execution of a virtual CPU of a virtual machine by receiving a first halt instruction from a corresponding virtual machine and determining whether the virtual machine is latency sensitive. If the virtual machine is latency sensitive, then a second halt instruction is issued from the virtual machine monitor to halt a physical CPU on which the virtual CPU executes. If the virtual machine is not latency sensitive, then a system call to a kernel executing on the host computer is executed to indicate to the kernel that the virtual CPU is in an idle state.Type: GrantFiled: April 12, 2016Date of Patent: September 11, 2018Assignee: WMware, Inc.Inventors: Haoqiang Zheng, Lenin Singaravelu, Shilpi Agarwal, Daniel Michael Hecht, Garrett Smith

Patent number: 10061610Abstract: A host computer has one or more physical central processing units (CPUs) that support the execution of a plurality of containers, where the containers each include one or more processes. Each process of a container is assigned to execute exclusively on a corresponding physical CPU when the corresponding container is determined to be latency sensitive. The assignment of a process to execute exclusively on a corresponding physical CPU includes the migration of tasks from the corresponding physical CPU to one or more other physical CPUs of the host system, and the directing of task and interrupt processing to the one or more other physical CPUs. Tasks of of the process corresponding to the container are then executed on the corresponding physical CPU.Type: GrantFiled: May 11, 2017Date of Patent: August 28, 2018Assignee: VMware, Inc.Inventors: Haoqiang Zheng, Lenin Singaravelu, Shilpi Agarwal, Daniel Michael Hecht, Garrett Smith

Publication number: 20170353534Abstract: The current document is directed to virtualized PMUs provided by virtualization layers. The currently disclosed virtualized PMUs are decoupled from the underlying PMU hardware features of processors on which the virtualization layer executes. The decoupling is achieved, in part, by time multiplexing the underlying hardware PMU registers to provide a greater number of virtualized PMU registers than the number of hardware-PMU registers provided by at least some of the underlying hardware PMUs. The decoupling is also achieved by providing for monitoring, by the virtualized PMU registers, of computed processor events and approximated processor events in addition to the processor events monitored by the underlying hardware PMUs.Type: ApplicationFiled: August 25, 2017Publication date: December 7, 2017Applicant: VMware, Inc.Inventors: Reza Taheri, Kalyan Saladi, Daniel Michael Hecht, Jin Heo, Jeffrey Buell

Patent number: 9552216Abstract: A host computer has a plurality of virtual machines executing therein under the control of a hypervisor, where the host also includes a physical network interface controller (NIC). An interrupt controller detects an interrupt generated by the physical NIC, where the interrupt corresponds to a virtual machine. If the virtual machine has exclusive affinity to one or more physical central processing units (CPUs), then the interrupt is forwarded to the virtual machine. If the virtual machine does not have exclusive affinity, then a process in the hypervisor is invoked to forward the interrupt to the virtual machine.Type: GrantFiled: August 25, 2014Date of Patent: January 24, 2017Assignee: VMware, Inc.Inventors: Haoqiang Zheng, Lenin Singaravelu, Shilpi Agarwal, Daniel Michael Hecht, Garrett Smith
