Research Highlights: Bare-Metal Performance for Virtual Machines with Exitless Interrupts
Communications of the ACM
Direct device assignment enhances the performance of guest virtual machines by allowing them to communicate with I/O devices without host involvement. But even with device assignment, guests are still unable to approach bare-metal performance, because the host intercepts all interrupts, including those generated by assigned devices to signal to guests the completion of their I/O requests. The host involvement induces multiple unwarranted guest/host context switches, which significantly hamper…
Direct device assignment enhances the performance of guest virtual machines by allowing them to communicate with I/O devices without host involvement. But even with device assignment, guests are still unable to approach bare-metal performance, because the host intercepts all interrupts, including those generated by assigned devices to signal to guests the completion of their I/O requests. The host involvement induces multiple unwarranted guest/host context switches, which significantly hamper the performance of I/O intensive workloads. To solve this problem, we present ExitLess Interrupts (ELI), a software-only approach for handling interrupts within guest virtual machines directly and securely. By removing the host from the interrupt handling path, ELI improves the throughput and latency of unmodified, untrusted guests by 1.3×–1.6×, allowing them to reach 97–100% of bare-metal performance even for the most demanding I/O-intensive workloads.

Condition based detection of no progress state of an application
שהונפקו US 8,392,765
A system, and computer usable program product for condition based detection of a no progress state of an application are provided in the illustrative embodiments. A resource usage and an output of a set of applications including the application are monitored. The resource usage and the output are measured to determine a resource usage value and an output value at a first time. A present condition is detected under which the set of applications is executing. A determination is made whether the…
A system, and computer usable program product for condition based detection of a no progress state of an application are provided in the illustrative embodiments. A resource usage and an output of a set of applications including the application are monitored. The resource usage and the output are measured to determine a resource usage value and an output value at a first time. A present condition is detected under which the set of applications is executing. A determination is made whether the resource usage value is included in a sub-range of a resource usage scale and the output value is included in a sub-range of an output scale where the sub-range of the resource usage scale corresponds to the sub-range of the output scale for the present condition. The no progress state of the application is detected if the determination is negative.

ENHANCING INTERRUPT HANDLING IN A VIRTUAL ENVIRONMENT
שהונפקו US 20130174148
Systems and methods for enhancing the handling of interrupts in a virtual computing environment are disclosed. A CPU is configured such that the CPU, when in a virtual machine (VM) mode, directs an interrupt to a VM. When in the VM context, a guest in the VM is run with a hypervisor interrupt descriptor table (hypervisor IDT) to determine how the interrupt should be handled. The hypervisor IDT directs an interrupt that is to be handled by the VM to an interrupt handler in a guest IDT without…

When in the VM context, a guest in the VM is run with a hypervisor interrupt descriptor table (hypervisor IDT) to determine how the interrupt should be handled. The hypervisor IDT directs an interrupt that is to be handled by the VM to an interrupt handler in a guest IDT without causing a transition to the hypervisor. If an interrupt is to be handled by the hypervisor, the hypervisor IDT causes a transition to the hypervisor.
