  • Publication number: 20150055499
    Abstract: 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 processing of the packet handling interrupt is delayed.

  • Publication number: 20150058847
    Abstract: 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.

  • Publication number: 20130219389
    Abstract: Methods, apparatus, and articles of manufacture to virtualize performance counters are disclosed. An example method includes scheduling a virtual machine on a processor, incrementing a virtual performance counter in response to an occurrence of a speculative event during direct execution of guest instructions by the virtual machine on the processor, and incrementing the virtual performance counter in response to an occurrence of the speculative event during execution of emulated instructions by a hypervisor on behalf of the virtual machine on the processor.

  • Publication number: 20120317551
    Abstract: The invention is directed to instrumenting object code of an application and/or an operating system on a target machine so that execution trace data can be generated, collected, and subsequently analyzed for various purposes, such as debugging and performance. Automatic instrumentation may be performed on an application's object code before, during or after linking. A target machine's operating system's object code can be manually or automatically instrumented. By identifying address space switches and thread switches in the operating system's object code, instrumented code can be inserted at locations that enable the execution trace data to be generated. The instrumentation of the operating system and application can enable visibility of total system behavior by enabling generation of trace information sufficient to reconstruct address space switches and context switches.
